Alstom Grid agile digital substations – key advantagesBased on the IEC 61850 unifying communication standard for complete information, future modernisation and the integration of new systems.Digital Control Systems may connect with the primary bays via a process bus built on redundant Ethernet architectures. Merging and control units collect and translate measurements, indications and commands (I/O) from the primary equipment into sampled values and GOOSE messages and vice-versaDigital instrument transformers and HMI (Human Machine Interface)-integrated condition monitoring systems for the primary equipment can be added, providing superior substation situational awareness locally and remotely.

Optimise your operational costsAsset managers now have a critical tool that, with less wiring and fewer commissioning tests, optimises preventive maintenance and can extend the lifetime of the entire substation, including third party plant items.Alstom Grid’s digital solutions:

■■ Maximise the reliability of your substation■■ Operate assets more efficiently and safely close to the limits of the system■■ Optimise maintenance, repair and retrofit of equipment with minimal outages

Complete and adaptable solutionsAlstom Grid’s digital solutions solutions are available for:

■■ Retrofit and extension schemes, as they reinforce conventional tools and systems■■ New substations■■ The particular solution and architecture can be adjusted to meet your operational needs according to how critical your asset and substation is to the network.

■■ Extensions and modifications are easier, as the substation functions via software, not hardware.

11

Alstom Grid’s digital substation – the benefitsIncreased reliability and availabilityThe extensive self-diagnostic capabilities of digital devices ensure the maximum availability of the substation, as well as its full suite of functionalities: any degradation in the performance of an asset is pinpointed in real-time.The inherent redundancy built into the system can be employed to self-heal and permits troubleshooting without the need for primary system outage.

Optimised operation of assetsThe intelligence within digital substation schemes allows close monitoring of the load capacity of plant equipment, based on their design ratings. This dynamic load analysis means that lines, cables, transformers and other grid equipment can operate closer to their limits.

Improved safety■■ Removal of wired cross-site CT (Current Transformer) circuits reduces the risk of fatal injury due to inadvertent opening of the circuit by personnel

■■ Absence of oil in transformers reduces explosion risks■■ Advanced self-monitoring of substation assets ensures that they are operating within safe limits

Reduced maintenance costsThe digital substation closely monitors all substation assets in terms of operational conditions, effective load capacity and asset health indicators. Intelligent systems analyse the data and provide recommendations on maintenance and repair actions. This allows a shift to predictive maintenance, avoiding unplanned outages and emergency repair costs.


12

Investment optimisationThe capital cost of investment projects is reduced on many fronts:

■■ savings on the time needed to engineer and install substations■■ reduced real-estate needs■■ copper cabling is cut by up to 80% through the use of optical fibre■■ asset optimisation tools allow faster targeting of weak areas which need to be reinforced, allowing for reduced operational costs

Easier renovation and extension of existing substationsInteroperable solutions and the use of fibre optics instead of copper wires reduce the duration and costs of unavailability of substations during the refurbishment phase of secondary equipment. This also applies to extension works.

Standardisation and interoperabilityBeing IEC 61850 compliant, Alstom Grid digital solutions and substations are designed to be interoperable with other vendors’ equipment, with a strong degree of standardisation at the interface level of secondary equipment systems.

Improved communication capabilitiesData exchange between intelligent devices, intra and inter- substation, is optimised through Ethernet communications. Smart local and wide area control units allow data exchanges between voltage levels within substations and between substations.Direct inter-substation communication without the need to transit via a control centre reduces the response times, enabling fast, real-time applications.

13

IEC 61850: the key technology enablerModern sensors and other Intelligent Electronic Devices (IEDs) must be connected to communicate within the substation and over the greater grid system. In the past, there were many different protocols requiring much effort to make them communicate with each other. Insufficient standardization, fear of degraded reliability and lack of return on investment slowed down the emergence of the fully digital substation. But today, the IEC 61850 standard makes it possible to facilitate interoperability between different equipment and suppliers.Introduced in 2004, the IEC 61850 standard is increasingly accepted across the world, as its main objective is to ensure interoperability between equipment coming from various suppliers. IEC 61850 continues to evolve and encompass the needs identified by the industry’s user group (UCA UG),


14

ensuring that it caters to all substation needs. IEC 61850 is rapidly being enriched as new application areas are continually added, most notably IEC 61850-8-1 and IEC 61850-9-2.This permits the full digitising of signals in a substation so that large amounts of data can be managed and communicated for the real-time management of a modern power grid – a smarter grid.

IEC 61850IEC 61850 is the international standard for Ethernet-based communication in substations. It is more than just a protocol, it is a comprehensive standard designed for utilities, to deliver functionalities that are not supported in legacy communication protocols.IEC 61850 defines a domain specific data model (data and services) supporting all functions required in substations. These unique characteristics can significantly reduce costs associated with designing, installing, commissioning and operating power systems.IEC 61850 is designed for interoperability and longevity, removing the dependence on one supplier and one generation of IEDs.

IEC 61850-8-1IEC 61850-8-1 is the relevant standard for the station bus. It defines the means to generate and present reports which may be subscribed to by other devices and HMIs (Human Machine Interfaces) as well as the way to communicate peer-to-peer. The latter is achieved by the exchange of GOOSE messages between devices on the LAN (Local Area Network).

IEC 61850-9-2IEC 61850-9-2 is the part of the standard that brings non- conventional instrument transformer technology into play, breaking the constraints of conventional CTs and VTs. It is particularly important for the process bus, as it describes how analogue signals such as phase currents and voltages can be exchanged as sampled values.

The architecture of Alstom Grid digital substationsAlstom Grid’s digital substations incorporate the newest DS Agile digital control system that provides the complete architecture, connecting all the components, together and with the operator interface, through an IEC 61850 Ethernet network.DS Agile digital substation solutions are highly scalable in terms of equipment, functions, architecture and services.

A typical Alstom Grid digital substation solution incorporates many components, all designed for optimal inter-operability, data retrieval, protection and control capability and remote settings. Its architecture is organised on three levels:

1. The process levelA digital substation is based on a communicating architecture, where real-time operational measurements and other data are polled from the primary system by sensors embedded within the primary system. This data is communicated to devices that must act on those measurements (pressure or temperatures in GIS switchgear, current and voltage measurements) via a “process bus”.Most important is that smart devices and systems within the substation, (protection relays, recorders, phasor measurement units, bay controllers, wide area controllers) can immediately process this data. By subscribing as clients to this data flow over an Ethernet process bus, the information from the ‘eyes and ears’ of the power system is distributed and communicated much more efficiently to the bay level than in conventional hardwired schemes.The process bus is also the link by which the primary equipment information from out in the yard travels back to the substation control room.

In a fully digital architecture, control commands are also routed to the primary devices via the process bus. The process bus, therefore, enables time-critical services.

2. The protection and control levelBetween the process bus and the station bus are devices identified as ‘secondary equipment’.In the digital substation, these devices are IEDs (intelligent electronic devices), interacting with: the field via the process bus; with other peer devices in the bay; with other bays, and with the digital control system via the station bus. They are designed to provide the Smart Grid applications demanded by utilities via real-time and secure equipment. They provide interoperable solutions, stability applications, wide area protection & control plans, and more globally, substation situation awareness.

19

Key components are: the protection relays, bay controllers, switches and Ethernet network, measurement and recording devices, substation proxy, the operator user interface within the substation control room, time synchronization units, security applications and the panels where all this equipment is commissioned and energised. IEC 61850 communications enable complete integration between devices. It ensures optimal use of the information for the continuity and reliability of electrical grid operations in secured access situations.

3. The station control areaThe digital substation station bus is much more than a traditional SCADA bus, as it permits multiple clients to exchange data, supports peer-to-peer device communication and links to gateways for inter-substation wide-area communication.The IEDs perform their time critical functions such as protection, point-on-wave switching supervision and other tasks via direct interaction with the process bus.Additionally, other clients in the substation may require information-sharing of some or all of this data. For example,

protection and control schemes may be distributed amongst multiple IEDs.There is also the need to distribute the information to local or remotely-stationed control operators so they can visualise the operational status of the substation in real-time. This requires substation HMIs, proxy server links to remote HMIs and control servers. One or more workstations can apply the instructions assigned by regional dispatchers, or can be used as an engineering workstation for IED configuration, or for local concentration and archiving of power system data. Online condition monitoring may have specific workstations for alerts and to manage the database history of each primary device.Using industry norms and enabling technologies to their fullest, Alstom Grid’s global experts now bring the digital substation to the market. Whether for incremental refurbishment, or complete green-field installations, Alstom has the equipment, the system delivery capability and project management expertise to be operational first time and on-time. The component parts of this offer are detailed in further sections.

Digital instrument transformersDecades of extensive research by Alstom Grid has delivered proven non-conventional instrument transformers, designed to be accurate, intelligent, safe, cost-effective – and very importantly – core-less.The root of many of the limitations of conventional instrument transformers is their reliance on an iron core. The core is a source of inaccuracy, due to the need to magnetise it, but not to overflux it. In the case of conventional CTs, achieving the low- level accuracy and dynamic range to satisfy both measurement and protection duties is a challenge. Conventional VTs may experience ferroresonance phenomena resulting in thermal overstressing.Instead of an iron core, the translation from primary to secondary measurement uses optical, Rogowski or capacitive technology, with the optimal choice for AIS (air-insulated substation) and GIS (Gas-Insulated Substation) equipment driven by the size of the respective digital device, which allows size optimisation for the switchgear.A wide array of sensors monitor conditions in real-time thanks to multiple applications: diagnostic analysis, asset management and condition-based maintenance.

■■ Long-term accuracy■■ Outstanding seismic resilience

■■ Unparalleled reliability and availability with full self-diagnostics

■■ Lightweight, compact and flexible

■■ Minimal inventory, near-zero maintenance

The facts■■ Optical sensors use the Faraday effect. A fibre optic loop sensor carrying a polarised light beam encircles the power conductor. This light will experience an angular deflection due to the magnetic field, generated by the primary current flow. The sensor’s intelligence is to accurately determine the primary current based on the real-time optical measurement.

■■ Rogowski sensors dispense with the conventional CT core and instead implement windings as tracks on a multi-layer printed circuit board. Four quadrants of the board are clamped together to form a toroid around the primary conductor. The sensor output becomes a low-level voltage measurement, which can be accurately correlated to the primary current.

■■ Capacitive dividers dispense with the conventional VT core. Capacitors are built from slimline film stacks for AIS sensors or printed circuit board electrodes laid on the interior of the enclosure for GIS sensors.


23

Primary convertersConverters Alstom Grid digital substations optimise the amount of electronics residing in potentially harsh outdoor environments.The primary converters convert analog signals from the primary equipment into digital signals. Primary converters can be installed either directly in primary plant hardware or in cubicles.Digital controllers (switch control units) are the fast, real-time interface to switchgear, mounted close to the plant that they command. They replace the hardwiring of inputs and outputs with an Ethernet interface to the yard.

Merging units Merging units perform all the digital data processing necessary to produce a precise, time-aligned output data stream of sampled values according to the IEC 61850-9-2 standard. This processing includes tasks such as sampling, analog to digital conversion, scaling, precise real-time referencing and message formatting.The design may vary with the applied technology of the instrument transformers (eg: optical, Rogowski, voltage dividers, or conventional wound instrument transformers), the switchgear type, mounting space available and also with the preferred substation communication architecture.

Control and MonitoringAlstom Grid’s DS Agile range is the latest generation of substation Digital Control Systems (DCS). It relies on fast Ethernet networks with IEC 61850 communication standards and offers topology-orientated automation combined with electrical security to minimise outages.DS Agile can be tailored either to single substations or to a harmonised system across multiple substations.

Devices Applications

DS Agile bay controllers (C-series)

Alstom’s IEC 61850-compliant bay controllers, like the C264, provide embedded or programmable fast automation (automatic voltage regulation, synchro-check, auto-recloser, busbar transfer, etc.), backup feeder protection, data concentrator, events and waveform recorder, hot standby redundancy etc.

DS Agile OI Real-time, user-friendly Operator Interface (OI) for complete substation automation

Also available, the MiCOM P847 phasor measurement unit offers industry-leading accuracy and dynamic response to frequency excursions.The MiCOM P594 provides the precision clock source reference for merging units and phasor measurement units in the substation.MiCOM Alstom IEDs extend their supervision facilities to address and check the plausibility of the incoming sampled values from the process bus. This addresses the fact that the traditional task of current and voltage sampling is now external to the device, and is connected via Ethernet. The supervision compensates for any latency or mismatch in the network, provides ride-through intelligent compensation in the event of several missing samples or jitter, and blocks/alarms if the quality of incoming data compromises the secure and reliable operation of the IED.

27


Redundant architecturesDS Agile architectures can be set up as a self-healing ring (HSR protocol) or dual-homing star (PRP protocol); both of which are fully redundant, eliminating outages.Fibre optical networks link all the system’s components together and with the operator interface (HMI), via a full range of Ethernet switches that provide full reliability and interoperability.

Substation/grid control room communicationsThe digital substation benefits from a wide-area network interface, receiving and responding to the data from its extensive array of sensors and IEDs. It can be integrated as part of the grid operator’s wide area control systems and defence plans, as the data from Phasor Measurement Units (PMUs) is concentrated and relayed from the substation to the control centre and analysed by online stability solutions to track current oscillations and anticipate incidents.Alstom’s digital substation sensors and control systems work seamlessly with its software platforms for grid operator control rooms, allowing a real-time data exchange both at the substation operational data level and at the asset management data level. This substation / control room communication introduces Smart Grid capabilities to the network, bringing complete synergy between field equipment operations and network management systems.The networks can be local to the substation or they

Customer benefits■■ Reduced unscheduled outages and repair times

■■ Reduced routine maintenance costs

■■ Increased equipment life expectancy

■■ Frees-up skilled personnel for remote diagnostics and operation centres

28

Cyber securityThe digital substation brings increased cyber security capabilities, as intrusion protection and protection against virus attacks are integrated in switches and IEDs. Cyber security provides protection against unauthorised access to equipment and unauthorised transfer, modification or destruction of data – whether deliberate or accidental.Particularly when wide area networks extend beyond the traditional substation fence, cyber-security measures are essential. Security procedures, controls, firewalls and role-based access are all examples of such measures. A number of standards apply in this area, typically: NERC CIP, IEEE 1686, IEC 62351, ISO/IEC 27002, ETSI and CEN CENELEC.

Online condition monitoring and asset managementOnline condition monitoring functions are essential for power transformers, circuit-breakers, disconnectors and gas-insulated switchgear.Physical parameters are continuously monitored and real- time measurements are combined and compared to models in order to generate specific recommendations for operations and maintenance, as well as alarms when necessary.Expert software providing additional advance warnings, automatic diagnostics and maintenance suggestions will boost the efficiency of asset management. An interface with an asset management system yields additional features such as remaining lifetime or dynamic rating capabilities.This architecture gives operational and maintenance teams an overview of the condition of all substations in real-time, so they can make appropriate strategic asset management decisions.

Agile Digital Substations | Q&A

Digital substation solutions – Q&A

33

34

“I am not sure about the reliability and accuracy of process bus solutions”

“These systems transfer too much unnecessary/ unimportant information”

“The information which is delivered is too complicated to analyse”

Regarding reliability and system architecture: Sometimes users express concern about the architecture of the digital solutions because it is different. With analogue solutions the information chain was: sensor then cable then relay. Now the route is different with sensors, fibre optics, station bus and process bus. Even though the architecture may seem more complex to non-specialists, the solution is extremely reliable, because it has auto-test and health-check capabilities that analogue solutions do not have.

Regarding accuracy: The information is digitised from the source, so the information conveyed is very accurate. Indeed, accuracy is much improved, especially with digital instrument transformers, as there is no CT/VT iron core to magnetise or introduce measurement error.

Digital solutions are able to capture and transfer a lot of information, not only simple 0/1 values. Of course, more information means users have to interpret it and to define for each parameter the alarm thresholds. Alstom offers many functions to make the best out of digital systems.a. Expert support is available at all stages to design and parameter,

analyse etc.

b. Alstom solutions offer user-friendly interfaces with simple colour coded indicators: green = ok, orange = warning, red = not ok.

c. Alstom solutions enable users to select the information displayed according to the user’s profile, as operation staff, maintenance staff or asset managers do not need to monitor the same things.

Alstom makes it possible to give the right information to the right person. For example, the systems can generate data sets for managers once a day, while they can display the information in real time for operation people.

Let’s share some of the questions we have heard asked about digital substations so far, and the answers we provided..

35


“What about the life time of electronic components?”

“What will happen if we need to replace components?”

“Only experts can use the information received from these systems”

Electronic components obsolescence is a point of interest for network operators although such technologies are now used in many industrial applications, and well-proven in Digital Control Sytems and numerical protection relays.

Solutions are designed incorporating the necessary ‘functional sustainability’ which implies that all new developments will replace/be compatible with older generations. Changing a component in 20 years, while keeping the same functionality, is made easier with Alstom.

As regards the life time of digital components, the MTBF of many components is actually several decades.

Temperature is the most impactful parameter when talking about the life time of digital components and the industry improves continuously. Alstom choses electronic components that have been selected to withstand higher temperatures and therefore feature longer service life.

Furthermore Alstom solutions withstand extensive thermal testing during their design and development.

Last but not least: with analogue solutions, if a component does not work, you might not know it unless you perform visual tests. Digital solutions incorporate automatic health check and if a component is out of order, it will give a signal, ensuring the reliability of the whole solution.

And what may happen in 15 or 20 years if a component might need to be replaced?

Alstom ranges are managed so as to replace the components and solutions gradually as they become obsolete, maintaining the same functionality. Service specialists are dedicated to supporting customers after the warranty period and to supply with the right component or solution.

d. Alstom solutions can concentrate and filter information before it is sent to upper levels of the system hierarchy. This avoids placing unnecessary bandwidth constraints on the communications network.

36

“Implementing digital solutions will be difficult”

“We do not have the skills in-house to implement such systems”

Implementing a substation with digital control and monitoring will actually be easier than implementing a substation with analogue systems. The main reason is that the whole cabling adventure is a thing of the past! Cabling in a HV substation is reduced by approx. 80%.For the design and implementation of the digital systems themselves, Alstom experts provide support and all the solutions are scalable, meaning that they can be implemented one stage at a time.

For example, conventional current and voltage sensors can be linked via fibre optics to digital merging units and protection relays, so as to reduce the cabling, while keeping the conventional substation equipment.

Note that much of the digital system engineering is in software, which means that the maximum can be engineered and proven before the FAT (factory acceptance test). The site works are drastically reduced, meaning that the more senior specialists need not travel to each project site.

Alstom delivers training to all involved staff:

■■ Architecture and design of solution ■■ Maintenance ■■ Operation■■ Asset management

The younger generation of network engineers are educated and very familiar with these technologies. As the future is digital, the training and knowledge gained is career enhancing, so utilities can remain attractive to talented young engineers!

“The information given by the system requires highly skilled people to interpret it”

Alstom solutions range from the most basic information delivery to expert systems. We are able to discriminate the right information for the right person according to his/her position and profile. Expert systems also include some analysis and clever data display, so as to make the reading and interpretation easier. Training is available for all positions from operational staff to asset management executives.

“Is it right that the safety of my staff can be enhanced?”

Digital devices run on Safety Extra Low Voltage (SELV), meaning that staff are at no risk while working with them.

The elimination of oil in instrument transformers (removal of explosion risk), and the removal of cross-site current transformer circuits (risk of lethal injury if open-circuited whilst live) are the two principal examples of staff safety being improved.

“What are the references?” or “which utilities have already implemented such systems?”

In 2013, Alstom has installed a base of:

■■ Protection : over 400 000 digital relays ■■ Control : more than 3000 control systems ■■ Monitoring : more than 1300 GIS bays

There are specific case studies in the ‘Reference Projects’ section of this handbook.

RECT: High-tech sensorSensors are the basic elements of current measurement. In order to get the best results for final measurement or protection applications, the sensor must be highly accurate and should be protected against the electromagneticperturbations (EMC) found in GIS substations.

Sensors are designed based on an Alstom patent, using a double-sided PCB (printed circuit board) as sensor material. This provides an excellentstability in the measurements, even when temperature and currents have slight variations.

Compatible with all GIS typesSeveral sensor designs have been introduced to cover all types of high voltage equipment. RECT sensors are available for all GIS equipment. Theirsmall size allows for smaller enclosures and consequently smaller GIS substations.

Less maintenanceThanks to the coating on the PCBs and the highly accurate processing, the sensors are designed to work whether conditions are optimal or not.

An external memory (EEPROM) is associated to the sensor allowing all calibration values to be stored as soon as the sensors are mounted.

Thus, when a sensor is connected to the PC12 primary converter, the electronics automatically adjust the compensation gains related tocalibration values found in the EEPROM.

Maximum protection against EMCBased on an Alstom patent, sensors are on a double-sided PCB with interlaced copper tracks, providing high immunity against EMC and external magnetic fields.

The PCB is shielded to have a perfect immunity against nearby magnetic fields.

RogoFlex® : Flexible current sensorSensors are the basic elements of current measurement. In order to obtain the highest accuracy for protection applications, the sensorshould measure the current with the best linearity and repeatability.

It should also be protected against the electromagnetic perturbations (EMC) found in GIS substations.

Sensors are designed based on an Alstom patent, using flexible polymer pipes as wiring supports with a shielded double winding.

Compatible with all GIS typesThanks to their design, RogoFlex® sensors are flexible and the length of the ‘ring’ can be calculated for each application, depending on conductor diameter.

These sensors are available for the entire GIS range from 72.5 kV to 1200 kV or higher. Thanks to their flexibility, RogoFlex® sensors can be installed in retrofit in existing substations without designing specific enclosures and with no need to remove HV parts.

The sensors can be opened if needed (e.g. inspection). The open/close mechanism is rugged and locks the external tube.

Less maintenanceAn external memory (EEPROM) is associated to the sensor, allowing all calibration values to be stored when the sensors are mounted.

PC12: A high-tech converterThe digitising of signal outputs from DITs is crucial and requires state of the art electronics using high-speed and high-accuracy components.

The PC12 is a smart converter providing high performance and reliability. It is based on a digitalconversion unit and a digital core (FPGA: programmable gate array) for signal treatment, management and communication.

An analog condition circuit, digital filters and integrator provide low noise, high linearity and high bandwith to the converter.

Compliant with all GIS layouts and with a rugged and compact design, the PC12 can be easily integrated with all HV products in voltage ranges up to 1,100 kV. The 3-phase design means only one converter is required for a 3-phase measurement point.

The design is particularly adapted to harsh environments where Electromagnetic Compatibility

(EMC) can be a problem, as is the case withGIS substations in most layouts.

Easy to maintainThanks to its modular concept, the replacement of a PC12 module is as simple as an off-the-shelf replacement.

Calibration values for sensors are included in the sensors themselves and pre-stored in an EEPROM memory unit before leaving the factory.

If a PC12 needs to be replaced, as soon as the new sensor is plugged in, the calibration values are automatically swapped to PC12 internal memory.

Several communications ratesHigh-speed electronics allow the simultaneous transmission of protection, metering and qualimetry sample value outputs according to the IEC 61850-9.2 / 61869-9 standards.

The design meets Smart Grid requirements up to harmonic 100 on the qualimetry channel.

System composition1. A set of UHF modules, which are dedicated to

signals acquisition and pre-treatment.

2. A central unit dedicated to recording the signals, generating alarms and displaying data to users.

Predict potential faultsThe system is permanently fitted into the substation and can be queried remotely. Thanks to this system,developing dielectric faults can be detected and eliminated before complete breakdown occurs. Used with suitable couplers, this system can detect all critical defects such as particles, coronas, free potentials and insulator voids at the sensitivityspecified by CIGRE TF 15/33.05.03.

The link between the UHF modules is ensured by a 100 Mbit/s ethernet network with self-healing features, providing greater reliability.

External noise discriminationIn order to avoid spurious alarms, signals generated by real partial discharges must be distinguishablefrom external noises: the detection of UHF signals is based on calculations of spectrum key features, such as average and variance.

The key features are calculated by placing specific masks on the spectrum to exclude the known externally disturbed frequency bands. Thispossibility is not currently offered by broadband systems using thresholds on analog signals.

A clever algorithm validates an event generated by a threshold on the mean and variance of the spectrum by making an analysis of signals oninternal and external noise sensors.

Short and long term analysisA trend curve shows the evolution of the UHF signals level inside the GIS over the short and long term. It is very useful for riskassessment because the UHF signals level is not fully linked to the partial discharge level (due to factors such as the kind of defect orthe distance to coupler, ). This evolution of UHF activity is crucial to the determination of the defect’s severity.

A single HMI with monitoringThe HMI shows the Single Line Diagram with gas compartments and PD couplers. It is thus common to both PD monitoring and SF6 density monitoring, avoiding the need for multiple HMIs. This tool also brings important time savings thanks to automatic test report generation.

Auto-test functionThe status of the complete system is continuously checked, including the couplers: the HMI displays an indication if a UHF module is out of order, if a UHF coupler is disconnected or if a synchronisation signal is absent.

RPH3Point on Wave switching Optimising the closing and opening of a circuit-breaker is of the utmost importance because random switching can result in high transient overvoltages and/or high inrush currents. These transients generate stresses on all substation and network equipment, leading to accelerated aging - or the worst case scenario - flashover of the HV apparatus.

Controlled switching of high voltage circuit-breakersThe RPH3 is an advanced microprocessor-based synchronising relay suitable for Independent pole operated circuit-breakers. More commonly referred to as a Point-on-Wave controller, it protects high voltage network components from transients generated during switching operations.

Thanks to the RPH3’s sophisticated algorithms, the operation of the circuit-breaker is configured to reduce stress in all conditions and network configurations.

Random switching operations on high voltage networks cause electrical transients that stress equipment and degrade power quality.

The way to deal with switching transient phenomena is to act efficiently on their root-causes.

Eliminate random switching and replace these practices with a controlled switching strategy - or “point-on-wave” switching.

Point-on-wave controlled switching consists of

issuing switching commands to the circuit-breaker at the optimal point on the reference voltage waveform. Thanks to its electronics and software, the RPH3 point-on-wave controller effectively sends a switching command to the circuit-breaker to operate at the correct instant, thus eliminating or substantially reducing transients.

Perfect matching with the circuit-breaker under controlSuccess of controlled switching operations depends on the ability of the RPH3 controller relay to assess beforehand the reference synchronising voltage, as well as the characteristics and the consistency of circuit-breaker operations under all operating and ambient conditions.

To optimise the performance of the RPH3 in its controlled switching operations, the relay can be programmed according to network and circuit-breaker operational characteristics.

Thanks to the permanent monitoring of the circuit-breaker’s parameters and the sophisticated adaptive

Synchronousswitching relay

control routines, the RPH3 enables a reliable and accurate control over the behaviour of the device, thus permitting optimal switching sequences.

Advanced communications features and user friendly interfacesWith its integrated memory and communications ports, the RPH3 records switching parameters and communicates the results of controlled switching operations.

An embedded web server for the machine interface allows:■■ Real-time information on the RPH3 device & application status■■ Configuration of parameters needed for controlled switching applications

■■ Retrieval of switching archives and data from RPH3 devices

The web server program operates by accepting HTTP requests from the client via a standard web browser.

The ‘RPH3 Manager’ dedicated software allows the analysis of archive records stored in the RPH3 relay in service and can perform data evaluations of controlled switching operations.

The reduced size and weight are attractive benefits compared to conventional oil-filled equipment, allowing placement in compact substations or in retrofit applications where space may be limited.

A lightweight dry-type insulator and window head design allow pedestal mounting or suspension from a rigid bus.

Its broad dynamic range makes this CT particularly suited for both high-precision metering and protection applications at the same time.

The accurate measurement of DC and AC to the 100th harmonic and the measurment of phase angle is a must for new Smart Grid applications.

The standard digital interface will ensure smooth integration of COSI-CT in the digital substation application.

Basic Faraday effectIn Faraday Effect current sensors; the current flowing through a conductor induces a magnetic field that affects the propagation of light traveling through an optical fibre encircling the conductor.

A linear state of polarization rotates in the presence of a magnetic field because the field produces a circular birefringence in the glass. Birefringence refers to an optical material with two indices of refraction.

Metering and protection accuracyThe COSI-CT design permits measurements to be made with the highest possible accuracy and stability. To address stringent revenue metering applications, its performance exceeds IEC Class 0.02S and IEEE Class 0.3 accuracy (optional 0.15%) with a dynamic range that extends from 1 A to 5000 A.

The COSI-CT has ultra-accurate and stable phase measurement, which is critical for intertie metering. For protection applications, the COSI-CT exceeds IEC Class 5P accuracy ratings and IEEE 10% accuracy ratings.

Wide dynamic rangeAccuracy specification is maintained over a broad dynamic range - from 0.2% to 150% of rated current (extended metering range sensor) and up to 171 kA (protection range sensor). Broad dynamic range allows elimination of separate high and low range CTs.

Wide bandwidthAccurate waveform reproduction up to 6 kHz allows full power quality analysis of harmonics and transients with no sensor-imposed limitations.

Dry type insulator seismic stableField-proven lightweight composite insulator reduces transportation costs, substation support structure requirements, and installation equipment demands. The lightweight design also allows location in seismically active areas.

Choice of connection optionNew window head design allows a variety of connection options including standard NEMA pads, up to 300 mm rigid bus, or flexible cable pass through, allowing optimal selection for ease of installation and reliability.

Green designThe COSI-CT insulator contains no oil, SF6 or other gas. There is no internal mechanism for violent failure to endanger personnel or adjacent equipment. There are no environmental concerns or gas to recycle. With an optical design there are also no open secondary concerns.

Low maintenanceThe COSI-CT has no active components at line potential, eliminating the need for costly outages to maintain the electronics. Since there is no insulating oil or paper there are no complex maintenance procedures. The polymeric insulating column employs silicone rubber sheds that do not require liveline washing.

Smart Grid ready with digital interfaceThe standard digital interface will ensure smooth integration of COSI-CT into digital substation applications the accurate measurement of harmonics and phase angle is a must for new Smart Grid applications.

Three product types are available, Type A, Type B, and Closed Loop, each optimised for different applications and specifications.

Each F3 has a wrap-around sensing head around high-voltage bushings, generator buses, and other conductors in ways not possible with conventional Current Transformers.

The sensing loop is an all-dielectric cable, which connects to the standard electronics, giving the user the same highperformance capability and output options as the high-voltage optical CT. It is an ideal solution for retrofit applications and installations in difficult spaces, on a temporary or permanent basis.

Type A F3 Current TransformerThe type A F3 CT is a fibre optic current sensor consisting of an electronics module, a fibreglass sensor box, and a flexible PVC conduit wrap-around sensing cable.

The sensing fibre resides in the PVC conduit, which attaches directly to the sensor box.

Standard telecommunications optical fibre cabling and wire cabling connect the electronics module to the sensor box. Because the sensor box has a wire connection to the electronics, it should not be installed in a high-voltage environment.

However, it may be installed in a low-voltage environment, allowing the sensing cable to be wrapped around a high-voltage bushing.

107

The type A F3 CT has metering grade accuracy to 0.15%, and it can measure both AC and DC currents with this accuracy from 1 A to 160 kA, depending on the number of sensing cable wraps used to measure the current.

The cable length between the electronics module and the sensor box can be up to one kilometer. The sensing cable has a standard length of 20 m, but other lengths may be specified at the time of order.

The output of type A F3 CT can be analog with 1 A or 5 A for metering application or digital for metering and protection applications.

■■ Applications include metering and protection, wrap-around bushing for metering or protection, DC valve hall measurements for metering and protection, and very large aperture applications.

Type B F3 Current TransformerThe type B F3 CT is a fibre optic current sensor consisting of an electronics module, a fibreglass sensor box, and a flexible PVC conduit wrap-around sensing cable.

The sensing fibre resides in the PVC conduit, which attaches directly to the sensor box. Standard telecommunications optical fibre cabling connects the electronics module to the sensor box.

In the type B sensor, no wire connection is required at the sensor box, allowing it to be installed in a high-voltage environment.

The type B F3 CT is a protection grade sensor with accuracy to 1%. It measures AC currents over a bandwidth of 10 Hz to 3 kHz and cancover a range from 1 A to 160 kA, depending on the number of sensing cablewraps used to measure the current.

Flexible Form Factor

108

The cable length between the electronics module and the sensor box can be up to 10 km. The sensing cable has a standard length of 20 m, but other lengths may be specified at the time of order.The output of the type B F3 CT can be an analog voltage (11.3 V full scale), a current (1 A or 5 A formats), or digital (IEC61850).

■■ Applications include protection, wrap-around bushing for protection, temporary field service measurements, and underground cable monitoring.

The underground cable monitoring application uses sensors at both ends of the underground line to measure the differential current. When the underground cable is in good condition, there is little to no difference between the two measured currents. But, when the cable between the two sensors has faulted, there is a substantial differential current.

Because the type B F3 CT sensor box can be placed up to 10 km away from its associated electronics, this line differential currentprotection scheme can be implemented at remote sites where there isno substation or power available (such as an overhead to underground line transition).

Closed Loop F3 CTThe Closed Loop F3 CT is a fibre optic current sensor consisting of an electronics module, a fibreglass sensor box, and a flexible PVC conduit wrap-around sensing cable.

The sensing fibre resides in the PVC conduit which attaches directly to the sensor box. Standard telecommunications optical fibre cabling and wire cabling connect the electronics module to the sensor box. However, it may be installed in a low-voltage environment allowing the sensing cable to be wrapped around a high-voltage bushing.

The Closed Loop F3 CT uses a current feedback to null the impact of the sensed current on the sensing cable. As a result, the Closed Loop F3 CT achieves accuracies Cl 0.1. Both AC and DC currents are measured from 1 A up to >500 kA.

The distance between the electronics module and the sensor box is limited to 100 m. The sensing cable has a standard length of 20 m, but other lengths may be specified at the time of order. The output of the Closed Loop F3 CT can be an analog voltage (11.3 V full scale), a 1 A current, or digital (IEC 61850-9.2).

Compliant with all AIS layouts and with a rugged and compact design, the PC13 can be easily integrated with all HV products in voltage ranges up to 1,100 kV. The 3-phase design means only one converter is required for a 3-phase measurement point.

The design is particularly adapted to harsh environments where Electromagnetic Compatibility

(EMC) can be a problem, as is the case withAIS substations in most layouts.

Easy to maintainThanks to its modular concept, the replacement of a PC13 module is as simple as an off-the-shelf replacement.

Calibration values for sensors are included in the sensors themselves and pre-stored in an EEPROM memory unit before leaving the factory.

If a PC13 needs to be replaced, as soon as the new sensor is plugged in, the calibration values are automatically swapped to PC13 internal memory.

Several communications ratesHigh-speed electronics allow the simultaneous transmission of protection, metering and qualimetry sample value outputs according to the IEC 61850-9.2 / 61869-9 standards.

The design meets Smart Grid requirements up to harmonic 100 on the qualimetry channel.

XMU820: Smart, powerful deviceAs soon as the analogue signals have been digitalised via the PC13, the data is sent digitally to the XMU820 merging unit. (Several PC13s can sendtheir measurements to one or more merging units).

The XMU820 merges all those digital signals and is also able to include analog signals coming from conventional VT & CTs and synchronises them using the 1 PPS (Pulse Per Second) input or IEEE1588 protocol. Then, the data is packed into one or several 61850.9-2 frames and sent to protection relays, data loggers, Smart terminals, etc. The device is powered by a powerful FPGA, creating a real time matrix for interconnections between HV Sensors (conventional and/or DIT) to secondary IEDs.

Compliant with AIS architecturesThe XMU820 design is compact, with all the communications ports at the back of the XMU box.

A mechanical form factor was chosen for simple integration into a 19-inch bay.

The large number of I/O ports allows the XMU820 to fulfill most AIS substation architectures (one busbar, two busbars, one and half circuit-breakers) thanks to the 13 Ethernet ports and 14 analog input terminals which can be used as PC13 and/or CT,VT inputs. All communication ports are designed with standard LC- type optical connectors or RJ45 plugs.

Highly communicative deviceThanks to its powerful core, the device is able to communicate via 61850.9-2 (& 9-2 LE) sending Sample Values (SV) to a 9-2 network simultaneously over several ports.

The CBWatch-2 monitoring system offers you the possibilities to manage a proactive, more cost effective maintenance programme by constantly monitoring your circuit-breakers’ condition and the trends in your operational parameters. These advance warning notifications are the best insurance to avoiding network failure and guarantee a longer life to your equipment.

The CBWatch-2 installs directly on the circuit-breaker and maintains a constant, monitored link with your local or remote database via the CBWatchTool software package. The monitoring system records information coming from the sensors installed on the breaker and analyses this information, comparing it with standard operational parameters programmed into the system.

SF6 or gas mixtureThe installation of the CBWatch-2 monitoring system makes it possible to constantly watch the gas pressure and temperature, calculating the SF6 or gas mixture density using the Beattie-Bridgeman algorithm. It detects and inhibits false alarms in the event of liquefaction. The system measures SF6 leakage rates giving you advance warning before sending alarms or reaching lockout threshold levels. The system also maintains historical records.

Mechanical operationCBWatch-2 monitors close and open operating times, allows the use of conventional auxilary switches or primary contact travel sensors, monitors primary contacts separation speed, buffering and over travel, detects mechanical performance deterioration (friction, corrosion, breakage, spring fatigue and buffer defects) and it monitors auxilary switch timing.

121

SwichingDuring switching, the CBWatch-2 monitors the current during breaking, arc duration, and estimates primary contact wear.

Auxiliary and control circuitsThe CBWatch-2 system monitors operating coil continuity, your auxiliary supply voltage and heater integrity.

Available versionsCBWatch-2 exists for circuit-breakers with one operating mechanism for all three pole or for one operating mechanism for each of the three poles.

CBWatch-2 also exists for generator circuit-breakers (please consult us for the available functions).

RPH3Point on Wave switching Optimising the closing and opening of a circuit-breaker is of the utmost importance because random switching can result in high transient overvoltages and/or high inrush currents. These transients generate stresses on all substation and network equipment, leading to accelerated aging - or the worst case scenario - flashover of the HV apparatus.

Controlled switching of high voltage circuit-breakersThe RPH3 is an advanced microprocessor-based synchronising relay suitable for Independent pole operated circuit-breakers. More commonly referred to as a Point-on-Wave controller, it protects high voltage network components from transients generated during switching operations.

Thanks to the RPH3’s sophisticated algorithms, the operation of the circuit-breaker is configured to reduce stress in all conditions and network configurations.

Random switching operations on high voltage networks cause electrical transients that stress equipment and degrade power quality.

The way to deal with switching transient phenomena is to act efficiently on their root-causes.

Eliminate random switching and replace these practices with a controlled switching strategy - or “point-on-wave” switching.

Point-on-wave controlled switching consists of

issuing switching commands to the circuit-breaker at the optimal point on the reference voltage waveform. Thanks to its electronics and software, the RPH3 point-on-wave controller effectively sends a switching command to the circuit-breaker to operate at the correct instant, thus eliminating or substantially reducing transients.

Perfect matching with the circuit-breaker under controlSuccess of controlled switching operations depends on the ability of the RPH3 controller relay to assess beforehand the reference synchronising voltage, as well as the characteristics and the consistency of circuit-breaker operations under all operating and ambient conditions.

To optimise the performance of the RPH3 in its controlled switching operations, the relay can be programmed according to network and circuit-breaker operational characteristics.

Thanks to the permanent monitoring of the circuit-breaker’s parameters and the sophisticated adaptive

control routines, the RPH3 enables a reliable and accurate control over the behaviour of the device, thus permitting optimal switching sequences.

Advanced communications features and user friendly interfacesWith its integrated memory and communications ports, the RPH3 records switching parameters and communicates the results of controlled switching operations.

An embedded web server for the machine interface allows:■■ Real-time information on the RPH3 device & application status■■ Configuration of parameters needed for controlled switching applications

■■ Retrieval of switching archives and data from RPH3 devices

The web server program operates by accepting HTTP requests from the client via a standard web browser.

The ‘RPH3 Manager’ dedicated software allows the analysis of archive records stored in the RPH3 relay in service and can perform data evaluations of controlled switching operations.

DS Agile key benefitsDS Agile is a complete substation automation solution whose typical architecture consists of a local IEC 61850 Ethernet network (LAN) that links all components, together and with the operator interface (HMI). The network can be local to the substation or can interconnect several dispersed substations. Redundant architectures can be set up as self-healing ring or dual-homing star; eliminating outages. All LAN configurations are linked to the grid control room.

Industry standardisationAlstom DS Agile offers topology-orientated automation protecting, controlling and monitoring installations to ensure continuity and reliability of electrical networks.Based on IEC 61850 communication standards, DS Agile enables complete integration between devices and therefore ensures optimum use of information.

Reliability and securityDS Agile provides ultimate reliability through the application of fully redundant architectures. This is reinforced by unmatched cyber security, at all levels throughout the digital substation.

Wide-area automationDS Agile is much more than a control and protection system for substations. Rapid data exchange and communications between all control and protection IEDs is enabled, not only across the substation and substation gateway, but also through Wide-Area Control Units (WACU) that can process real-time automation, taking into account the topology of multiple substations.The new WACU solution developed by Alstom makes inter-substation automation and protection possible, helping protect assets and optimise power flows.

Project delivery and supportAlstom has experienced teams located worldwide, with a proven track record in project management, engineering, application support, maintenance and training. Our experts can provide assistance in any or all of these areas, allowing users to make the best use of DS Agile.

DS Agile functionsData concentration and processing One of the main functions of the DS Agile is to concentrate and process data: the information can come from a variety of sources, both analog and digital. For example, when re-using legacy equipment, analog data can be acquired directly from current and voltage transformers and digital data can be acquired over serial communications links or via hardwired links.DS Agile manages many types of data from the substation’s primary and secondary equipment such as: tapchanger and switchgear positions, control signals, measurement values, disturbance records, settings, etc. Each item of qualified data is uniquely referenced in the system configuration tool in order to ensure full consistency of the information, as well as allowing it to be re-used in other parts of the system.

Extremely compact monitoring can be achieved via the embedded LCD in the C26x bay controller, displaying single line diagrams, alarms, measurement values and sequence of event lists.Alternatively, more sophisticated monitoring is possible via one or more flat screens, providing additional benefits such as busbar colouring for easier maintenance, advanced alarm screens and accurate fault localisation within the system. Other features include advanced reporting, dual language display and disturbance record analysis.

Control Controls can be initiated by the operator (locally or remotely) and multiple checks are performed before the issue of a control signal in order to make it fully secure. For instance, interlocking is achieved by logical equations or as the result of a dynamic topological analysis coupled with expert rules. Interlocks are managed as close to the process as possible in order to provide the best security of operation. Interlocking conditions are graphically displayed on the operator’s screen in order to immediately identify the locking conditions (if any), allowing the operator to make the appropriate changes before issuing the order.

Automation An operator can configure specific control sequences or automation schemes, across one or more sites (e.g. automatic reclosing, System Integrity Protection Schemes (SIPS), load shredding). Such applications can be based on local or remote data. Similarly, the outputs can perform local or remote actions. Programmable logic can be implemented using either Programmable-Scheme Logic (PSL) or the Programmable-Logic Controller (PLC). PSL is for fast automation applications and it is available in the C26x bay controller. It is event-driven, so there is no cycle time. The optional PLC tool is fully compliant with IEC 61131-3 and it can be used for complex or sequential automation applications, not only at bay level (in the C26x) but also at inter-substation (or inter-system) level, by means of the programmable Wide-Area Control Units (WACU).

DS Agile architectureHomogenous DS Agile offers a unified architectural framework for building multiple solutions tailored to the real needs of almost any application. It allows for progressive upgrading of the system design according to the evolving requirements in terms of functions, size, performance etc.

Extendable A DS Agile solution can be contained within a standard panel or be geographically distributed, depending on the application. The DS Agile architecture is structured in a series of hierarchical levels. Each level maintains a given performance in terms of transmission time, dependability and automation independently of the other levels. It therefore ensures that the system can be extended consistently and securely.

Standardised The combination of modern, multi-functional and highly programmable IEDs together with fast communications greatly improves the capabilities for producing a “standard bay”. A standard bay is a product made of standard hardware, software and engineering libraries (automation, graphical representations, wiring interface and IED composition). It can then be customised to the exact requirements of the project through changes to the database.

Reliable System availability is a function of the reliability of each individual component and the architecture in which they are combined. DS Agile accommodates a variety of redundancy options, ranging from the switch redundant power supply to the complete redundancy of each component, including configuration database redundancy.A DS Agile solution can be engineered from a few integrated components or have its functions split into several components, thus offering a balance between functional availability, cost and compactness.In addition to the self-checks carried out by each component, DS Agile offers a variety of system test modes such as ‘device maintenance management’ and ‘data forcing’ to further increase the overall availability.

152

Communications protocols Physical communications between components are based on both Ethernet and serial RS links in order to cope with different applications such as the re-use of existing devices and the integration of third-party equipment. State-of-the-art communications technology based on client-server and peer-to-peer links such as IEC 61850 is DS Agile’s standard. It relies on fast Ethernet networks and offers new perspectives in terms of distributed functions, performance and flexibility, enabling innovative automation schemes and the flexible addition of new application clients.In addition to Ethernet’s IEC 61850, DS Agile supports the most typical serial protocols (T103, DNP3 and MODBUS), in order to interface with existing devices, and it can be fully integrated within a remote control scheme. When using MiCOM Alstom devices, the same link can be used to retrieve settings or disturbance records.Communications with remote control centres is achieved using IEC 60870-5-101, IEC 60870-5-104 or DNP3 protocols. DS Agile also supports a series of older protocol generations.State-of-the-art communications technology based on client-server and peer-to-peer links such as IEC 61850 is DS Agile’s standard. It relies on fast ethernet networks and offers new perspectives in terms of distributed functions, performance and flexibility, enabling innovative automation schemes and the flexible addition of new application clients.

Simple architecture The DS Agile base architecture interconnects a Remote Terminal Unit (RTU) or a PC with a series of Intelligent Electronic Devices (IEDs) such as protection relays or measurement IEDs.This architecture is typically used within a simple distribution substation, a wind farm or a transmission substation bay (a feeder, for example).

Complete architectures A DS Agile complete architecture is made up of an ethernet network linking components from the base architecture with an operator interface (HMI), gateway and IEDs.The ethernet network might be local to a substation, typically for a transmission application, or it may interconnect dispersal sites commonly found in industrial or infrastructure applications through wide-area control units.The client-server communications exchange avoids any central point between local and remote control (as found in the simple architecture) and allows for tailored redundancy of the client and/or server.

153

The full architecture is also typically implemented as a way to make an existing installation evolve progressively via new technologies. The older system thus becomes a slave to an IEC 61850 converter and new devices can successively be plugged into this network.


DS Agile componentsA typical DS Agile Digital Control System (DCS) will incorporate different Intelligent Electronic Devices (IED, such as protection relays, measurement devices and monitoring equipment), bay controllers, Ethernet switches and gateways. All key components are designed for optimal interoperability, data retrieval, control capability and remote settings.

DS Agile substation server with DCS OI operator interface (HMI)The DS Agile system database is hosted in at least one Human-Machine Interface (HMI) server, but it may support two servers with hot-standby redundancy. The HMI itself can be hosted either in the main server workstation or in a dedicated one and supports up to 10 HMI Clients.The DCS OI software platform provides real-time access to all substation automation data and enables secure and intuitive control operation functions.

DS Agile bay controllersIEC 61850-compliant substation bay controllers that provide fast automation, embedded or programmable (automatic voltage regulation, synchrocheck, autorecloser, busbar transfer), IED interface for legacy protocol conversion, data concentrator, events and waveform recorder, hot standby redundancy and are adaptable for individual requirements. Alstom’s bay controllers, like the MiCOM C264, are proven solutions with more than 30,000units installed worldwide.

MU Agile merging units and DS Agile switchgear control unitsAlstom provides a full range of flexible merging units, allowing measurement conversion and switchgear control. Both AMU and SCU are based on proven architectures, such as those of MiCOM P40 Agile relays and MiCOM C264 bay controllers, respectively.

154


DS Agile switchesThe DS Agile H-series Ethernet switches combine interoperable redundancy protocols (such as PRP) and fibre-optic connections for ultimate reliability of the substation communication networks. They maintain the flexibility to connect to standard Ethernet networks for substation upgrades or refurbishments.

DS Agile communication devicesAlstom’s A-series provide powerful and ruggedised gateway and wide-area automation solutions for interfacing bay level devices, station level devices or upper level systems. They combine full IEC 61850 compliance with hot standby redundancy and simple commissioning.

MiCOM Protection rangeThe MiCOM Alstom and agile protection ranges provide a complete family of technologically advanced protection relays for the modern digital substation. Typical protection applications include busbar, transformer and line differential, distance, feeder, generator, motor and phasor measurement.

Condition monitoring IEDsA complete range of state-of-the-art systems for online condition monitoring of the primary substation equipment can be fully integrated within the DS Agile system, throughIEC 61850, to provide valuable online condition data, plus expert tools for safer operation, preventive maintenance and lifetime management of your assets.

Measuring and recording IEDsAlstom supplies advanced IEDs for highly accurate, real-time fault recording and analysis, power quality measurements and trend recording. They are the ideal IED for analysing network faults, protection IED reactions, dynamic network stability and long term trends.

155

DCS OIOperator interface (HMI) platform for substation automation While substations are usually unmanned during normal conditions, efficient information access is a key requirement in emergency situations. Design, installation, life extension and maintenance instances of an electrical substation’s digital control system (DCS) demand a straightforward, user-friendly interface. Intuitive access to the most relevant information and fully secure operations are necessary to ease operator tasks. To help you meet these challenges, we offer the Alstom DCS OI operator interface platform dedicated to our substation automation systems, DS Agile v5.0 and upwards, and PACiS (up to v4.6).

Native integration of substation requirementsAlstom DCS OI relies on a standard graphical user interface, enabling local or web visualisation of single line displays. The HMI’s true added value consists of a series of fully tested modules that match electrical application needs such as: real-time communication protocol interface, select before operate sequences, automation capabilities and no data loss guarantee.

Intuitive and fully secure interfaceAlstom’s DCS OI scans of two dimensional substation representations or remote visualisations of real time video significantly improve the operator’s understanding of the situation. Embedded buttons enable functions such as synchro-check or interlocking condition displays to greatly increase the safety of operation and maintenance actions. Multiple language management allows dynamic switching between task-oriented dialects (operation vs. maintenance), or between national languages.

Scalable platform tailored to your projectThe configuration of Alstom’s DCS OI is tailored according to the needs of each project. This includes the number and type of screens and engineering facilities. From a performance perspective, the HMI can be expanded seamlessly from a single box to a series of interconnected PCs - with partial or complete redundancy.

The interface is open to the integration of any additional software and may display any type of HMI, including real-time images issued from video cameras, providing a remote and secure view of the application.

Open and efficient interfacesThe DCS OI provides an open interface to multiple intelligent electrical devices (IEDs) and Master SCADA through the latest Ethernet protocol IEC 61850. Disturbance files (COMTRADE 97/2001) and setting data are retrieved on the same link without disturbing real-time performance, using pass-through technology.

Additional supported standards for data access include web access, SQLTM interface, COMTRADE archives or Crystal ReportTM.

157

Consistent suite of operator toolsHMI software tools cover the complete lifecycle of the electrical application including: system engineering, IED engineering, substation automation, network analysis, system maintenance and IED maintenance - all integrated with a consistent look and feel.The DCS OI can provide access to (as a complement to local HMIs) any remote connection to present real-time information and any archived data for maintenance and supervision. Remote access is available through PSTN, DSL, satellite link as a dedicated application or Web server.

OI hot redundancyThe DCS OI server redundancy is managed through a set of 2 HMI servers (named cluster). The OI client can be connected to one of the 2 servers.

Reconfiguration is automatically managed when the preferred server is reconnected. Each datapoint change is consolidated between the 2 servers (real-time data & historical data are the same on both servers).

Alstom’s C264 Bay Control Unit (BCU) is a sophisticated solution supporting many applications and functions for substation control, communication, monitoring, protection and automation.

Flexibility, reliability and ease of use are among the top features required in a substation computer; the MiCOM C264 has these features. A combination of dual redundant fibre optic Ethernet, modular I/O, an expandable design and an extensive library of functions make the C264 the ideal solution for a wide array of applications in substation digital control systems.In addition to the traditional data management (inputs and outputs) the DS Agile BCU can be used as a:

■■ Remote Terminal Unit (RTU)■■ Bay computer■■ Feeder manager (protection & control)■■ Substation automation processor■■ Sequence of Events Recorder (SER)■■ Automatic Voltage Regulator (AVR)■■ Measurement centre■■ Load shedding controller■■ Protocol converter■■ Substation gateway

Seamless modernisation of existing installations The C264 provides seamless integration with existing substation assets, thanks to its flexible interfaces and native expandability. Its powerful processing, communication and configuration facilities make it the ideal tool for upgrading substation supervision, automation andmaintenance.

Innovative real-time automation schemes MiCOM C264 enables innovative automation schemes thanks to extremely fast (event driven) Programmable Scheme Logic (PSL) and robust Programmable Logic Control (PLC).

Optimised engineering The multifunctional capabilities of the C264 optimise system engineering as fewer devices result in less wiring, training and maintenance.

Sample logical equations

167

ApplicationsBay/substation interlocking Alstom’s C264 provides two methods of interlocking:

■■ A logical equation based method■■ A topology based method, using predefined rules and substation topology

Interlocks are managed as close to the process as possible in order to provide the best security of operation. Interlocking conditions are graphically displayed in orderto immediately identify the interlocking conditions (if any) and make the appropriate changes before issuing the command.

Trip circuit supervision The purpose of this function is to supervise the continuity of the trip circuit of a circuit-breaker. Two options are available: two wires or four wires. The two-wire option verifies the trip circuit continuity when the circuit-breaker is closed.

The four-wire option permits verification of the continuity whether the CB is open or closed. In the case of single phase circuit-breakers the C264 can supervise the continuity of the trip circuit separately for each phase.

Automatic Voltage Regulation (AVR) The Automatic Voltage Regulation (AVR) function is used to automatically maintain the correct secondary side voltage of a tap changing transformer.

AVR in the MiCOM C264 is a compact voltage regulation solution for IEC61850 systems in electrical substations. It is able to manage one transformer or up to four transformers in parallel.

C264 AVR provides:■■ Active and reactive compounding in order to maintain the voltage at a remote location

■■ Homing in order to adjust a transformer to the voltage of the busbar to which it will be connected

■■ For transformers in parallel: Minimising circulating current method, master/follower mode

■■ Optimised transformer ratio

Auto-recloser The MiCOM C264 can manage one autorecloser per bay (up to 12 bays per unit). The integrated auto-reclosers can operate in 1 phase and/or 3 phase mode. Up to four autoreclosing cycles are available and the time delay for each is independently configurable. Auto reclosers can be initiated either internally in the bay unit or via external protection devices using digital inputs.

Synchro-check The synchro-check function can be used in conjunction with automatic or manual reclosure. The function (limited to one bay) determines the difference between the amplitude, phase angles and frequencies of two voltage vectors and uses this information to determine whether or not to

close the breaker. Locking and coupling modes are available and a deadline and dead bus logic are also included.

IED gateway and data concentrator One of the main features of the C264 is to concentrate and process data. This information can come from a variety of sources, both analogue and digital. For example, when re-using existing equipment, analogue data can be acquired directly from current and voltage transformers and digital data can be acquired over serial communication links or via hardwired links.

The DS Agile BCU manages many types of data: tap positions, controls, measurements, disturbance records, settings, etc. Each item of qualified data is uniquely referenced in order to ensure full consistency of the information, as well as allowing it to be reused in other parts of the system.


MiCOM C264 front view (40TE variant)

168

FeaturesCommunication protocols Alstom’s MiCOM C264 is fully compatible with many communication standards such as UCA2/IEC 61850, IEC 60870-5-104, DNP3, IEC 60870-5-101/103, and MODBUS.

Redundancy At substation level and / or bay level an optional redundant C264 can be used to avoid the loss of critical functions.

Digital inputs The MiCOM C264 offers five types of digital inputs:

■■ Single point■■ Double point■■ Multiple point■■ System input for internal C264 information

■■ Logical combination of digital inputs

All inputs are acquired and time-stamped with an accuracy of 1 ms.

Digital input processing In addition to de-bouncing many customisable filtering functions can be used to process digital inputs, including:

■■ Toggle filtering■■ Persistence filtering■■ Motion filtering■■ Undefined state filtering

Additionally a digital input can be manually suppressed, substituted, forced invalid and detected as faulty. Digital inputs can then be transmitted on the substation LAN using the desired protocol.

Binary counters Two types of binary counter are available; single counters for single data points and double counters for double data points. Counters can be transmitted periodically or on request. In the event of a supply interruption the counters can resume from their previously stored values.

Digital outputs Digital outputs can be used to apply a switching voltage to an external device. These outputs can be controlled in one of three ways:

■■ Select Before Operate once (SBO once)

■■ Select Before Operate many (SBO many)

■■ Direct executionThe SBO once mode is used for controls via set points or ancillary devices, as well as synchronised or non-synchronised circuit-breakers, transformers, disconnectors and earthing switches. The SBO many (selection, execution, and de-selection) control sequence is used for the control of transformers.

Encoded digital data The C264 BCU can interpret a group of digital inputs as an encoded digital value. Binary, Binary Coded Decimal (BCD), gray code, decimal and 1 among N types of encoding can all be processed. These values can represent data such as process measurements and tap positions.

Analogue inputs Analogue measurements can be acquired from either an analogue input board, a transducerless measurement board (for current and voltage transformers) or via a communication network.

Analogue outputs Analogue outputs can be used to interface with auxiliary devices (measurement viewers, generators, motors, etc). The Analogue outputs are powered from an external supply (48VDC) and can maintain their value even if the C264 is powered down.

MiCOM C264 rear view (40TE variant)

Measured and derived values Directly measured values of voltage and current can be measured using the transducerless measurement board. Many different values can be calculated from the measured values including:

■■ RMS currents and voltages■■ Network frequency and phase angle■■ Active, reactive and apparent powers - total and per phase

■■ Power factor■■ Sequence components■■ Derivatives: df/dt, dV/dt, etc

Waveform recording The MiCOM C264 provides two types of waveform recording, Fast Waveform Record (FWR), which stores samples at the maximum sampling frequency and Slow Waveform Record (SWR), which stores RMS measurements over a longer period. Both modes can run simultaneously. Recording can be triggered by, the change of state of binary digital inputs/outputs, measurement threshold violations and a request from an operator. Waveform records are stored using COMTRADE 2001 binary format.

Power quality Alstom’s C264 can measure the percentage Total Harmonic Distortion (THD) (up to and including 15th harmonic) and the Total Demand Distortion (TDD) on voltage and currents.

Self monitoring Comprehensive self-monitoring procedures, including power-on and continuous testing, ensure that internal hardware or software errors are detected and do not cause malfunctions. If a fault is detected an alarm will be issued and/or the watchdog contacts will change state depending on the fault severity.

Maintenance web server The maintenance web server can be used to visualise maintenance data (Hardware/Software, Communication, I/O values) and to download the up-to-date event log. It is directly accessible with a standard Internet Browser.

Programmable logic An operator can configure specific control sequences or automation schemes (e.g. automatic switching, System Integrity Protection Schemes (SIPS), load shedding). Such applications can be based on local or remote data. Similarly the outputs can perform local or remote actions. Programmable logic can be implemented in the C264 using either Programmable Scheme Logic (PSL) or the Programmable Logic Controller (PLC). PSL is for fast automation applications (<5ms). It is event driven and so there is no cycle time. The optional PLC tool is fully compliant with IEC 61131-3. It can be used for complex or sequential automation applications.

170


Local interface for control, operation and display The control of switching devices is possible using a keypad and a graphical backlit LCD. Operations can be performed in a simple and intuitive way via up to 12 switchable displays for bay control. Additionally there are dedicated panels for monitoring (i.e. measurements, events list, alarms, etc.), display and maintenance. If required the operator panel can be mounted separately from the C264 (up to five meters away). Access barriers can be used to guard against inadvertent or unauthorised operations.

Event logging Up to 2,000 events can be stored in nonvolatile memory. The events are time stamped and stored in chronological order.

Digital technologies have brought many benefits in the strategic field of transmission networks and specifically substations. Digital technology at station bus level is today widely spread and has also extended to process buses at the primary equipment level.

The Alstom MU Agile Analogue Merging Unit goes one step further towards a complete digital substation; facilitating the connection of conventional current and voltage transformers to modern substation automation solutions through IEC 61850-9-2LE.

With a space-saving case accommodating four current and four voltage transformers taken from the proven MiCOM P40 product range, the MU Agile AMU affords a low-risk transition from conventionally connected substation automation to a fully digital substation.

175

Configuration and status monitoringThe MU Agile AMU can be quickly and easily configured using the intuitive MiCOM S1 Agile PC tool suite via the front USB port.

A visual indication of the IEDs status via 4 tri-colour LEDs is available on the front panel. These are used to indicate the health of the IED, the time synchronisation status, whether it is out of service, and whether it has raised an alarm.

HardwareThe MU Agile AMU hardware offers:

■■ Support for 4 x CTs and 4 x VTs■■ Space-saving 4U height and 30TE (6”) case size■■ A front USB port and a rear fibre optic Ethernet port■■ Power-up diagnostics and continuous self-monitoring

■■ Time synchronization via fibre optic 1-PPS■■ N/O (form A) and N/C (form B) watchdog contacts

■■ Withdrawability

All CT connections have integral shorting, when the IED is withdrawn from the case. This affords additional safety to personnel who may be working near live apparatus.

Sequence of event recordingAll events are time tagged to a resolution of 1 ms. Up to 2048 time-tagged event records are stored in the flash memory, and can be extracted using the USB port.

CommunicationsTwo communication ports are standard: a rear port providing for process bus communications and a front port for substation staff. The front USB port facilitates the programming of settings, and the extraction and viewing of events. The rear fibre optic LC Ethernet connection offers the ability to transmit IEC 61850-9-2 sampled values and to receive SNTP time synchronisation messages.

Time synchronisationThe high-precision referencing of sampled values to GPS real time uses the one pulse per second (1 pps) fibre input, typically provided by the MiCOM Alstom P594.

Cyber-SecurityThe sophistication of protection schemes, coupled with the advancement of technology, increasingly leads to devices and substations being interconnected with open networks, such as the internet or corporate-wide networks. This introduces a potential security risk making the grid vulnerable to cyber-attack, which could in turn lead to electrical outages. To secure communication within such environments, the MU Agile AMU offers NERC-compliant cyber security.

Alstom Grid agile digital substationsAlstom Grid agile digital substations are based on IEC 61850, the unifying communication standard for complete information sharing and interoperability. They allow for future modernisation and the integration of new systems. Digital Control Systems are connected with the primary bays through a process bus built on redundant Ethernet. Merging and control units collate and convert measurements, indications and commands (I/O) into sampled values and GOOSE messages, and vice-versa.

At an advanced level, digital instrument transformers and condition monitoring systems integrated with the substation HMI (Human Machine Interface) can be added, providing superior substation situation awareness, locally and remotely.

IEC 61850-9-2LE process busIEC 61850-9-2LE facilitates the integration of non conventional instrument transformers into modern substation automation equipment. It also allows conventional current and voltage transformers to be interfaced to the same equipment via merging units. It describes how analogue signals such as phase currents and voltages can be exchanged as sampled values.

Benefits of IEC 61850-9-2LE

■■ Asset optimisation■■ Reduced maintenance cost■■ Optimisation of new investments

■■ Reliability and availability■■ Standardisation and Interoperability

■■ Ease of refurbishment■■ Safety■■ Environmental responsibility


Environmental ResponsibilityThe MU Agile AMU allows for the substitution of many copper cables with just a few optical fibres. In a full digital substation wiring can be reduced by up to 80%.

The IEDs are manufactured in a lead-free soldering process using lead-free components. This eco-responsibility is demonstrated in the Product Environment Profile (PEP). The PEP shows claims for raw material depletion, energy depletion, water depletion, global warming potential, ozone depletion, photochemical ozone creation, air acidification, and hazardous waste production. The IED does not require any resident battery.

Quality Built-InQuality Built-In methodology is applied throughout the development and manufacturing of the IEDs. Part stress analysis in R&D, rigorous component supplier selection, and a shipping carton compliant with ISTA protection requirements all are examples of best-practice to maximise long-life reliability. All circuit boards have harsh environmental coating, to resist moisture, salt, corrosive atmosphere and industrial ambient pollution – as standard. Circuit board production uses in-circuit tests, boundary scanning, built-in self-test, automated optical inspection, and X-ray scanning to achieve maximum test coverage.

Introducing Protection Relays

No matter how well designed, faults will always occur on a power system, and these faults may represent a risk to life and/or property. The destructive power of a fault arc carrying a high current is very large; it can burn through copper conductors or weld together core laminations in a transformer or machine in a very short time – some tens or hundreds of milliseconds. Even away from the fault arc itself, heavy fault currents can cause damage to plant if they continue for more than a few seconds.Uncleared faults would also pose a risk to system stability, resulting in unwanted disconnection of generation or interruption of supplies to consumers.The provision of adequate protection to detect and disconnect elements of the power system in the event of faults is therefore an integral part of power system design. Only by doing this can the objectives of the power system be met and the investment protected.

Figure 1 Programmable logic for P40

Protection and control featuresProtection elements All algorithm and hardware know-how is the culmination of decades of advances in Alstom’s centres of excellence. The platform has vast experience in test and in-service operational environments, proving the technical integrity.

The comprehensive and advanced library of protection and control functions in each device allow it to meet the exact application requirements. Multiple protection functions, logic and control functions may be enabled, without deterioration in performance – the platform is fully deterministic.

Independent protection settings groupsThe 40 series can offer up to four independent settings groups. These can be activated locally, remotely or via a dedicated input and are used to allow for different system operating conditions and where adaptive relaying is applied.

Programmable scheme logicPowerful logic available in the 40 series relays allows the user to customise the protection and control functions of the relay. It is also used to program the functionality of the opto-isolated inputs, relay outputs, LED and user alarms.

The programmable scheme logic can be used to implement additional supervision features, such as trip circuit supervision or implement complex logic such as frequency restoration schemes. Schemes have been developed capable of supervising the trip coil and circuit with the circuit-breaker open or closed.

The Px40 gate logic includes OR, AND, NOT and MAJORITY gate functions, with the ability to invert the inputs and outputs, and provide feedback. A number of general purpose logic timers are also available as well as those timers used to condition the relay contacts.

The system is optimised (event driven) to ensure that the protection outputs are not delayed by the PSL operation. The programmable scheme logic is configured using the graphical S1 Agile PC software, as shown in Figure 1.

Measurements, recording and post fault analysisMeasurement & post fault analysis The relays are capable of measuring and storing a wide range of system quantities such as current, voltage, frequency, power, distance to fault etc. depending on the relay functionality. These measured values can be displayed on the front LCD display or transferred locally or remotely per user requirements.

All event, fault and disturbance records are time tagged to a resolution of 1ms using the internal real time clock and are stored in non-volatile memory. Where relays are communicating with a SCADA system, the protocol’s telegrams can be used for external time synchronisation or alternatively an optional IRIG-B port is available for accurate time synchronisation on all P40 relays. Relays can also use an opto input to synchronise the internal clock.

Event records These are generated for status changes to logic inputs and outputs, modifications to one or more setting parameters and alarm signals.All events are time-tagged and stored in chronological order in cyclic memory. These are readily

available for viewing on the LCD, or by extraction via the communication ports.

Fault records Up to 15 records are supported for every fault (5 on some models), with the following information captured:

■■ A fault number■■ The date and time■■ The active setting group■■ The function that issued the trip■■ The magnitude of the current/voltage that gave rise to the trip command

Distance to fault calculation is provided on most feeder and line protection models.

Disturbance records The internal disturbance recorder will record the sampled values of all analogue input variables such as phase currents and voltages where applicable during a fault. Oscillographic analysis can be performed using the S1 Agile PC tool which will provide the means to quickly analyse analogue and digital signals on the same time scale for convenience. (Figure 2 on next page) Disturbance records can be extracted from the relay via the communication ports and saved in the COMTRADE format.

Relay communications As standard, a front communication port is available for local access to the relay. An auxiliary rear communication port is available

as an option on relays providing easy access to settings, records and measurements for protection engineers. A main rear communications port is also available for interface to a SCADA system. A number of protocols are available as an option for this purpose, with different media such as wired serial, fibre serial, RJ45 Ethernet, and fibre Ethernet.

Local communication The front EIA(RS)232 communication port has been designed for use with the S1 Agile software and is primarily for configuring the relay settings and programmable scheme logic. It is also used to locally extract event, fault and disturbance record information and can be used as a commissioning tool by viewing all relay measurements simultaneously.

Communication The rear communication port is based on EIA(RS)485 voltage levels and is designed for permanent multidrop connection to network control and data acquisition systems. Optional fibre optic and ethernet communications ports are also supported on the 40 platform, the latter available with redundancy.

186

The following protocols are available:

■■ Courier/K-Bus■■ Modbus■■ IEC 60870-5-103■■ DNP 3.0■■ IEC 61850

This flexibility allows the MiCOM Alstom P40 range of relays to be integrated into a SCADA system as well as to provide engineering data for remote access by utility engineers.

Redundant Ethernet communication MiCOM Alstom P40 series includes several redundant Ethernet options for IEC 61850 or DNP3/IP:

■■ Parallel Redundancy Protocol (PRP) according to IEC 62439-3

■■ Rapid Spanning Tree Protocol (RSTP)

■■ Alstom Self Healing Ring■■ Alstom Dual Homing

PRP has the advantage of taking zero time to recover from a failure, as parallel alternative paths are continually operative. All settings are configurable with the use of MiCOM S1 Agile.

User interfaces The ability to customise the menu text and alarm descriptions are supported on P*40. The front panel user interfaces, as per the example shown in Figure 3 comprise:(1) A back-lit liquid crystal display(2) Four fixed function LEDs

(3) Up to 18 user programmable LEDs(4) Menu navigation and data entry keys(5) “READ” and “CLEAR” keys for viewing and reset of alarms(6) An upper cover identifying the product name, which may be raised to view full product model number, serial number and rating information

(7) A lower cover concealing the front EIA(RS)232 port and download/monitor port(8) Facility for fitting a security seal(9) Up to ten programmable function keys with tricolour LEDs – for control and test applications and easy annunciation (not visible in the 40TE example shown)

187

Self monitoring Comprehensive self-monitoring procedures within the device ensure that internal hardware and software errors are detected, thus ensuring a high degree of reliability. Automatic tests are performed during start-up and cyclic self-monitoring tests are performed during operation. Any deviations are stored in non-volatile memory and the result of the fault diagnosis determines whether a blocking of the device will occur or whether only an alarm is issued.

Trip circuit supervision Supervision of the trip circuit, whether the breaker is closed or open (preclosing supervision), can be implemented using opto-coupled inputs and the programmable scheme logic.

Mechanical descriptionCases The Px40 series relays are housed in a specially designed case providing a high density of

functionality within the product. Communication ports and model/serial number information are concealed by upper and lower covers.

Physical protection of the front panel user interface and prevention of casual access is provided by an optional transparent front cover, which can be fitted or omitted according to choice, since the front panel was designed for IP52 protection against dust and water.

The cases are suitable for either rack or panel mounting as shown in Figure 4.

Taking into account the differing case widths, relays can be combined with or without the use of standard blanking plates to form a complete 19” mounting. This saves space and allows for a neat installation, especially in conjunction with MiCOM ALSTOM P*90 series interfaces, P991 and MMLG test blocks, and MIDOS auxiliary relays – all of which share the same 4U mounting dimensions.

The 40TE case width is often narrow enough to allow a retrofit of legacy vertically-mounted relays.

Wiring External connections are made via ring type terminals, for the peace of mind of secure ring lug and screw-through fastening. Ring terminals accommodate one or two lugs per terminal.

Technical dataMeasuring inputs – analogue All CT inputs are dual-rated at 1A and 5A to simplify ordering and strategic spares inventories.

The heavy duty terminal block features integral current transformer shorting to prevent dangerous voltages being present should the block be removed; a maintenance error could otherwise lead to a potentially unsafe/lethal scenario.

Measuring inputs – process bus IEC 61850-9.2 Many models in the range are available with an IEC 61850-9.2 process bus interface to replace traditional analogue inputs. This facilitates interoperability with non-conventional instrument transformers and merging units, with the measuring signals marshalled via Ethernet.

IEC 61850-9-2 process bus interface An optional process bus interface is available in MiCOM P40. It allows the relay to received current and voltage sampled data from non-conventional instrument transformers such as optical devices and Rogowski devices. In other digital substation architectures, the -9-2 data is generated by merging units in the yard, which digitize conventional 1A/5A and 100/120V secondaries, for safer and more economical cross-site communication to IEDs by fibre optic. Alstom’s -9-2

implementation has been designed to be especially resilient and reliable in the presence of “noise”, such as latency, jitter or missing/suspect data.

Power supplies Three ranges of power supply options are available at the

ordering stage to balance ease of deployment with energy efficiency.

Digital inputs (Optos) The digital status input pickup thresholds are programmable, so specifying the inputs is just a question of counting how many are needed.

Stability and thermal limits, voltage collapse and loop flows are constraints that electrical power system planners and operators continually have to deal with. With today’s stretched systems, often having minimal reserve, cascading events, such as the loss of generator units or transmission lines, can easily lead to severe power swings, voltage collapses, possible loss of synchronism and underfrequency load shedding. Real-time knowledge of system conditions and changes is at the heart of the battle to maintain security of supply.

The MiCOM Alstom P847 is a product that can help in this battle by providing highly accurate, time-synchronised phasor measurements (synchrophasors) from anywhere in the system.

Use the Phasor Measurement Unit (PMU) as part of a wide area monitoring and control system to assess key metrics in, or between, critical areas in the power system. High-speed transfer of key system parameters, complemented by cutting-edge visualisation tools at the control centre, enhances the system management capability.

■■ Anticipate impending system failures such as angular instability by monitoring bus angles between key generating areas

■■ Predict impending voltage instability problems by monitoring high VAR flows in the network associated with fast declines in regional voltage magnitudes

■■ Invoke system wide defence plans to ensure system stability is maintained.

■■ Improve control to prevent the risks of unnecessary islanding, damage to costly transmission equipment, unnecessary load shedding, and blackouts.

Physical communicationsGalvanic or fibre optic Ethernet communication ports are provided for streaming synchrophasor data. Redundant Ethernet is available, optionally managed by the market’s fastest recovery time protocols: ‘self-healing’ ring and ‘dual homing’ star, allowing bumpless redundancy. IEC 62439 PRP and RSTP are also available, offering multi-vendor interoperability.

IEEE C37.118 synchrophasor communicationsThe MiCOM P847 supports synchrophasor data transmission according to IEEE C37.118 via UDP/IP and TCP/IP. Synchrophasors to be transmitted via IEEE C37.118 can be selected from the available set, by simply enabling or disabling them in the PMU configuration column of the menu.

199

Software toolsSoftware tools are available for the configuration, monitoring and analysis of multiple P847 PMUs. All PMU settings can be configured using MiCOM S1 Agile locally or remotely.

Dynamic performanceUnder dynamic system conditions the PMU needs to track system parameters very accurately and this is ensured with an advanced frequency tracking algorithm able to perform accurately even under off-nominal frequency and abnormal voltage and current conditions.

Programmable Scheme Logic (PSL)Powerful graphical logic allows the user to create customised logic schemes using logic gates, latches and timers. Inputs to the PSL can include digital inputs and programmable function keys; outputs can include programmable LEDs, user alarms and IEEE C37.118 digital data.

User InterfaceThe front panel user interface consists of an LCD display, navigation keypad, 10 programmable function keys, fixed function LEDs and 10 programmable function LEDs.

Password protectionPassword protection may be independently applied to the front user interface, front communications port and rear communications port. Two levels of password protection are available providing access to the controls and settings respectively.

Event recordsUp to 512 time-tagged event records are stored in battery backed memory.

Disturbance recordsThe oscillography can record up to 12 analogue channels and 32 digital channels at a resolution of 48 samples per cycle. Disturbance records can be extracted from the relay via the remote communications and saved in the COMTRADE format.

Language supportThe user interface and menu text are available in English, French, German and Spanish as standard. The ability to customise the menu text and alarm descriptions is also supported.

Quality Built-in (QBi)Alstom Grid’s QBi initiative has deployed a number of improvements to maximise field quality. Harsh environmental coating is applied to all circuit boards to shield them from moisture and atmospheric contamination. Transit packaging has been redesigned to ISTA standard, and the third generation of CPU processing boosts not only performance, but also reliability.

Related productsPhasor TerminalPhasor Measurement Units (PMUs), such as the MiCOM P847, output synchronised phasor data over an Ethernet network at rates of up to 60 frames per second. This results in large amounts of data being produced that can be challenging to handle in real time when commissioning or troubleshooting an individual PMU or even a small Wide Area Monitoring System (WAMS).

Phasor Terminal solves this problem; it is a software tool that provides clear visualisation and archiving of real time IEEE C37.118-2005 data. Multiple PMUs can be quickly and easily configured, connected and graphically compared using an intuitive drag-and-drop interface.

Substation Phasor Data Concentrator (sPDC)In support of the MiCOM P847 PMU, a Substation Phasor Data Concentrator is available to aggregate and time-align high speed synchronised data from multiple P847s into a single data stream.

The PhasorPoint sPDC offers the following functionality:

■■ Receives multiple PMU streams■■ Phasor stream rate conversion■■ Phasor stream time alignment■■ Multi-rate stream outputs■■ User defined content for stream outputs (managing data provided to third-parties)

■■ Local rolling buffer storage■■ Data recovery for upstream archive (PhasorPoint Central PDC based systems only)

■■ Cyber-security

ApplicationsSynchronised phasor measurements can be transmitted by the MiCOM Alstom P847 to a PhasorPoint Phasor Data Concentrator (PDC) or other upstream application using a high speed communications link. The applications that can be deployed to utilise synchrophasor data include wide area monitoring, visualisation and alarming, post-event analysis, islanding detection and oscillatory stability management.

Islanding, Resynchronisation and Blackstart (IRB)The MiCOM Alstom P847 can be applied to make synchronised measurements of key variables such as voltages, currents and phase angles at strategic busses and corridors in the transmission system.

These measurements can be used by the PhasorPoint Islanding, Resynchronisation and Blackstart (IRB) application to aid the operator before, during and after an islanding event.

Oscillatory Stability Management (OSM)Synchrophasor data from the MiCOM Alstom P847 can be used by the PhasorPoint Oscillatory Stability Management (OSM) application to allow power system operators to visualise and analyse real time power system dynamics. By studying the oscillatory modes of a power system this application can be used to detect and manage power system oscillations which can be a sign of system instability.

Main featuresProduct variantsThree models of the MiCOM P847 Phasor Measurement Unit are available: A, B, and C. Model A features a three-phase VT input and a three-phase CT input and provides phasor measurements of the three-phase voltages, the three-phase currents and the derived sequence components. Basic protection functions including under and over, frequency, voltage and current, and circuit-breaker monitoring are included in the P847 A.

As well as the three VT inputs, Models B and C feature twelve CT inputs. The CT inputs can be configured as 4 sets of three-phase measurements or 12 independent phasor measurements. No protection functions are available in Models B & C. The functions available in each model are outlined in full in the table overleaf:

Agility, versatilityMiCOM P40 Agile IEDs provide an integrated solution for the complete protection, control and monitoring of electrical power systems. Application for overhead lines, underground cables, busbars, breakers, transformers, reactors, distributed generation and motors is supported, right from distribution (as primary protection) to transmission voltage levels (as back-up). The IEDs are suitable for application in solidly-earthed, resistance earthed and Petersen coil systems alike.

The perfect balance: standardised and adaptableWith a wide range of protection functions as standard, MiCOM P14N, P14D and P94V IEDs also offer additional pre-configured applications for smaller generators and a choice of functionality applicable to overhead lines. This allows the user to conveniently scale the application, which is then readily adapted via simple enable/disable feature selection in the configuration menu.

The IEDs offer a universal wide-range power supply, universal 1A/5A CT inputs (software selectable), and universal binary inputs - the latter with programmable pickup thresholds. Harmonisation at just one ordering option is often possible, easing the task of creating standard cubicle designs and strategic spares holding.

Environmental responsibilityThe IEDs are manufactured in a lead-free soldering process using lead-free components. Power dissipation is the lowest among comparable products, easing concern on station batteries. Even the product weight (including packaging) has been optimised to lessen the transit carbon footprint. All such actions boost the eco-responsibility demonstrated in the Product Environment Profile (PEP). The product does not require any resident battery.

The PEP shows claims for raw material depletion, energy depletion, water depletion, global warming potential, ozone depletion, photochemical ozone creation, air acidification, and hazardous waste pollution.

Quality Buit-InQuality Built-In methodology is applied throughout the development and manufacturing of the IEDs. Parts stress analysis in R&D, rigorous component supplier selection, and a shipping carton compliant with ISTA protection requirements are all examples of best-practice to maximise long-life reliability. All circuit boards have harsh environmental coating, to resist moisture, salt, corrosive atmosphere and industrial ambient pollution - as standard. Circuit board production uses in-circuit tests, boundary scanning, built-in self test, automated optical inspection, and X-ray scanning to achieve maximum test coverage.

Figure 2 depicts the software scalability of models, within the overall superset of the range functionality. The strong P40 family identity offers high customer familiarity, with minimal training requirements.

Cyber-securityThe sophistication of protection schemes, coupled with the advancements of technology, increasingly leads to devices and substations being interconnected with open networks, such as the internet or corporate-wide networks. This introduces a potential security risk making the grid vulnerable to cyber-attack, which could in turn lead to electrical outage. To secure communication within such environments, MiCOM P14N, P14D and P94V offer NERC-compliant cyber security.

Asset life extensionIn addition to new-build, P40 Agile IEDs can be used to refurbish legacy protection schemes. As MiCOM P14N and P14D are pin-to-pin compatible with KCGG14x and KCEG14x respectively, they can simply be plugged-in to the K relay cases for an easy upgrade. This draw-out and substitute strategy dramatically reduces the refurbishment time and cost.

Compact | Multifunction | Versatile P60 Agile One Box solutionsThe P60 range is suitable as main or backup protection for a wide range of typical applications and covers all common power system earthing arrangements such as solid, resistive, or resonant earthing and isolated networks. The colour touch-screen HMI with provision for bay mimic display and integrated control / interlocking functions maximises the application range of the P60 family. The fully programmable nature of P60 Agile makes it an extremely versatile and cost effective solution for all switchgear applications with varied protection requirements.

Alstom’s one box solution brings touch-screen technology into the substation. Switchgear control and single-line diagram presentation is achieved thanks to the full colour, graphical HMI.

The P16x series comprises the P161, P162 and P163 feeder management IEDs. Each requires a shallow depth of only 90 mm behind the panel, for ease of mounting within any switchgear cabinet. High performance features include 1.5 ms GOOSE, graphical logic, colour bargraph displays, and optional motor protection. IEC 61850, Modbus, Profibus DP, CANBUS and IEC 60870-5-103 protocols are available for full system integration.

Human machine interfaceThe P60 Agile has a state-of-the-art HMI with intuitive and easy navigation across the full range of its features and functionality. The membrane keypad hosts up to 6 configurable function keys and eight programmable LEDs, in addition to a USB port for communication with the PC-based configuration software.

The default HMI may be configured to display user preferences such as the single line diagram or load flow parameters such as voltages or currents instead of the Main Menu shown. The IED’s touchscreen along with hotkeys facilitate quick and convenient access to the whole menu system.

Up to four user-defined pages are available in the home menu, with easy touch-screen navigation from one to the next.

Switchgear controlThe P60 Agile offers comprehensive switchgear control, aided by the dynamic single-line-diagram display, ON/OFF switching via the function keys and programmable bay and inter-bay interlocks. Up to five (5) switchgear elements may be switched by the P60 Agile bay control models. The single line diagram for the bay or a subset of the substation, along with relevant data such as measurements or alarms, may be generated by the user via the P60 configuration tool, aided by integrated graphical icons. Remote controls are facilitated by the relay’s SCADA communication interfaces.

The provision of such powerful control capacity within the relay (the “one box” concept) negates the need for external control, switches and annunciation on the panel. Equipment cost and panel engineering time is reduced. For ease of operability and security of the command, dedicated open and close push buttons are provided on the P60 Agile front panel.

Protection + Control + Measurement + Recording = One-box solution

Example single line diagram (SLD) display

ApplicationsFeeder protectionAll models of P60 Agile provide full-featured overcurrent and earth fault protection, with six stages and a choice of definite-time or IDMT characteristics, including reset curves. Applications involving directional earth fault are covered by the P162, and the P163 provides full directional control of phase and earth fault elements in four independent stages. Harmonic stabilisation for inrush, voltage control and customisable directional characteristic boundaries all add to the versatility of the feeder protection

functions. Sensitive earth fault (SEF) applications are also covered by the P60 Agile with a choice of CTs for the neutral input.

Core balance CTs may be connected for maximum sensitivity, also the neutral displacement voltage may be fed from a broken-delta VT where available. The integral multi-shot autoreclosing function supplements the application of feeder protection where transient faults on overhead lines are expected.

Distributed generation protectionThe P163 relay features two-stage voltage vector

surge protection for islanding applications, with the enhanced security of supervision by load current change. Three stages of df/dt (rate of change of frequency) are also available in the P163, with the flexibility of configurable hysteresis and supervision by frequency thresholds and/or direction.

The P163 also features under/over voltage and under/over frequency protection with twelve (12) stages each and the possibility of assigning the measurement to any of the three-phase VTs signals in the relay hardware on a per-stage basis, thereby securing the applications against the loss of a single VT input.

214

Dynamic grid supportThe P60 is designed with the need for availability of modern high voltage and medium voltage networks in mind. In the event of single or multiple short circuits in medium or high voltage networks, immediate mains decoupling of distributed generation may be allowed only under specific conditions defined by the operators. The P60 Agile includes custom functions for fault ride-through with up to ten (10) permissible voltage dips and for reactive power direction protection, and has been KEMA certified in accordance with the requirements of the BDEW utilities’ standard, Germany.

Functional OverviewProgrammable Logic Control (PLC)The P60 Agile relays feature comprehensive programmable logic, with logic gates, flip-flops, counters, timers and timed switches. Users can customise the logic associated with protection functions via the PLC, combining outputs from the function block, binary input signals and and inter-device signals (IEC 61850 GOOSE) in the PLC. Up to 500 logic gates can be programmed.

Configuration of breaker or switchgear element control utilises similar logic capability,

with customisable triggering logic, interlocking and bypass features for each control action (eg: opening, closing, earthing) associated with the switchgear element.

User-programmable alarm conditions can trigger on-screen customised text alarms. Each text field can be up to 40 characters, enabling alarms to be simple and explicit for maintenance/operational personnel.

Each alarm, and each entry in the event record can be colour-highlighted to correspond with the urgency, or customer classification desired.

Four alternative settings groups are provided, such that P60 Agile may adapt to switched or emergency feeding scenarios.

Platform OverviewThe P60 Agile is designed for reliability with four powerful microprocessors and an integral cross-monitoring feature. The slim profile hardware (< 90 mm depth) makes it easy to fit into any switchgear compartment. The compact design together with the robust stainless steel housing provides rigidity, a wide operating temperature range, and maximum shock and bump capability for even the most demanding applications. The design pedigree draws from utility, industry, marine and genset installed base experience.

■■ The innovative design of the P60 allows functions to be distributed between hardware and software implementation. For example, the eight freely-programmable physical LEDs can be supplemented with virtual LEDs on the LCD screen.

■■ Terminal blocks on the rear of the device are typically pin-type and encapsulated, for safety of personnel even when a cabinet door is even open.

Measurements, recording, and post fault analysisMeasurementsAnalogue measurement values are clearly displayed on the HMI screen. A subset of principle values may be placed alongside the single line diagram, with the full suite of measurements accessible within the menu. Real-time measurements are shown as accurate digital quantities, with a corresponding bar graph alongside. Each bar changes from green to orange and then red, annunciating normal loading, overloading and excessive loading in a way that is clearly visible by substation staff. Alternatively, voltage and current vector (polar) diagram displays may be consulted.

In addition to directly measured analogues, power, (including power factor) and energy measurements are provided for the P163. Energy measurement is accumulated in all four quadrants: kWh, kVArh, import and export. Frequency statistics track the present, maximum and minimum frequencies, in order to trend the stability of the network frequency.

Operation logs count the number of operations of each switchgear device. For 3-position devices, the number of open and earthing operations are accumulated independently.

High accuracy meteringThe P60 Agile platform offers measurement CT inputs optionally, for applications where high accuracy metering is called for. The measurement CT inputs are accurate to 0.2% for currents up to 3 in, and are intended for use in combination with an external metering class CT.

RecordsThe P60 Agile relay records up to 3000 sequence of events records in a FIFO buffer. Time-tagging is to a resolution of 1 ms. Disturbance recording stores the analogue waveforms and binary signal data to allow in-depth post-fault analysis. Typically ten disturbance records are stored.

Alarm managementThe P60 features include extensive alarm management capability, keeping in view its role as the protection, control and measurement device for a bay. The HMI display has a configurable Alarms page, which is opened on occurance of any alarm. Alarm names may be configured by the user, along with a software LED which helps the user to recognise the alarm status - whether it is active, active and acknowledged or inactive and not acknowledged. The configuration tool allows the user to derive alarms as a combination of events available in the relay data model; up to 449 alarms may be defined, and allocated to alarm groups for efficiency.

KEY FEATURESPower transmission and distribution networks worldwide depend on reliable and highly available protection and control systems. These systems in turn depend on reliable and highly available communications networks for control, data collection, automation, monitoring and much more.

Alstom Grid’s H series Ethernet switches use a combination of advanced redundancy protocols and fibre-optic connections to ensure the reliability, availability and dependability of substation communications networks. All this while maintaining the flexibility of being able to be connected to standard ethernet networks - ideal for substation refurbishments or upgrades.

The H series switches use either the PRP, Dual Homing Star or Self Healing Ring protocols and are available in standalone, embedded and PCI card (for integration into a PC) variants. As part of Alstom Grid’s Digital Control Systems (DCS), the H series switches are fully compatible with our protection relays, bay computers and gateways.

ArchitectureDS Agile’s H series is a complete portfolio of ethernet switches for all substation automation applications covering: standalone DIN-rail switches, embedded switches in protection relays and bay computers and PCI internal switches for gateways and substation PC’s.

Alstom Grid’s Ethernet network architectures reduce the cost of ownership, as embedded switches in Intelligent Electronic Devices (IEDs) reduce the number of external switches required. This has the advantage of reducing the overall power burden, reducing the maintenance requirements, reducing the required number of connections, improving communications availability and reducing unwanted downtime.

Reference Projects

DENMARKEnerginet, Denmark – Digital Current Measurement and ProtectionOne current application is on Energinet’s transmission system, in a differential protection application. The protected circuits are hybrid lines, consisting of 400kV lines, and cabled portions laid sub-sea.

REFERENCE PROJECT

The cables are over 20km in length, and the operational demands are such that autoreclosing is required for faults on the overhead lines, but not for faults within the underground cable sections. The differential protection is thus used for fast and precise detection of faults within the cables. The undersea cables run from stations on the Jutland mainland, on to Funen island and then onwards to Zealand.

The equipment supply includes 72 optical CT units, 24 merging units and 24 line differential relays which subscribe to the sampled values in a process bus protection scheme. The principal reason for selecting to use non-conventional

instrument transformers was due to their low mass and slimline construction. In the Energinet substations, the optical CTs are mounted on the same support structures as the cable bushings themselves. A single structure and foundation per phase carries the larger mass of the cable, plus the optical CT support on a cantilever frame.
