1. Description

PML630 is a power management IED thatprovides comprehensive load-sheddingsolution for the power network in anindustrial plant. It protects the plant againstblackouts and power source outages due tosystem disturbances. This IED is a member of

ABB’s Relion® product family and a part ofits 630 series characterized by their functionalscalability and flexible configurability.

PML630 supports the IEC 61850 standard andoffers seamless connectivity with other Relionseries IEDs and COM600 Station Automationdevice to realise the load-sheddingfunctionality. The IED uses GOOSE and MMScommunication profiles for I/O dataexchange with other Relion series IEDs andCOM600 Station Automation device.

2. Power managementsystems

Power Management Systems (PMS) areessential for safe, efficient and reliableoperation of a power system within anindustrial complex. PMS functionality suiteincludes load-shedding, power sharing,network synchronization and powerrestoration.

PMS solutions protect and optimize thestability of industrial systems againstdisturbances by ensuring power sharingbetween generators when the industrialpower system is islanded from the grid.These solutions also ensure that thegenerators meet the required power demandwhen the network is grid connected. Load-shedding functionality ensures poweravailability to critical process loads bytripping less process critical loads.

PMS solutions are suitable for medium orlarge industrial power networks during thefollowing conditions.

• When the industrial power networks with in-plant power generation work in parallel orisolation with grid

• When the industrial power networks havesubstantial electrical load and critical loads

• When the industrial plants are located inremote locations without power gridconnectivity

• When the industrial power networks havegrid connectivity characterised by poorstability and/or availability

3. Application

PML630 provides system level protection tosmall or medium industrial systems fromsystem disturbances. The IED supports threetypes of load-shedding functions.

• Fast load-shedding• Slow load-shedding• Manual load-shedding

The fast load-shedding function protects thepower network during a power deficit. Anetwork power deficit happens when agenerator, a grid transformer, a bus coupler,or a bus tie feeder circuit breaker trips. In afrequency based load-shedding scheme thefrequency drop, caused by power deficit,triggers the shedding of loads in feeder IEDs.This information is pre-set in thecorresponding IED. This sometimes can leadto over shedding.

The fast load-shedding function takescorrective action before the system frequencydrop and provides faster and accurate load-shedding action based on power balancecalculations and defined priorities. Thus thefunction also contributes towards fasterimprovement of the frequency profile of thesystem.

The slow load-shedding function prevents thetripping of a grid transformer when themeasured current exceeds the preset currentlimit for a defined time duration. The slow


Revision: A

ABB 3

load-shedding function triggers the fast load-shedding function to initiate the load shedaction.

The manual load-shedding function shedsmultiple load feeders based on the definedload-shedding priorities.

PMS functionality suite is applicable invarious industrial segments. Some of theindustrial segments are Oil and Gas, Marine,Pulp and Paper, Metals, Minerals, andBuilding automation.

4. Communication

PML630 supports the IEC 61850 substationautomation standard including horizontal

GOOSE [1] and vertical MMS communicationprofiles.

PML630 is optimized to interoperate withRET615, REM615, REF615, RET630, REM630,REF630, REG670 and COM600 StationAutomation device. All operationalinformation and controls are availablethrough the IEC 61850 communicationprofiles.

Disturbance files, available in a COMTRADEfile format, can also be accessed using theIEC 61850 standard's MMS file transferservices or any standard protocol like FTP.The IED can send and receive binary andanalog signals to other IEDs (horizontalcommunication) using the IEC 61850-8-1GOOSE profile. PML630 meets the GOOSEperformance requirements for trippingapplications like load-shedding in distributionsubstations, as defined by the IEC 61850standard. The IED can interoperate withother IEC 61850 compliant IEDs, tools andsystems and simultaneously report events tofive different clients on the IEC 61850 stationbus. The IED is connected to Ethernet-basedcommunication systems via the RJ-45

connector (10/100BASE-TX) or the fibre-opticmultimode LC connector (100BASE-FX).

IEC 61850 GOOSE communication profile forload-shedding offers several advantages.

• Data transfer based on reliable and provenEthernet technology

• Substation LAN infrastructure for binaryand analog data exchange between the IEDs

• Eliminated hard-wired I/Os• Faster performance than hard-wired I/Os

and hence a distinct advantage for load-shedding application

• Easy implementation of change(s) insubstation configuration

• Supervised data transfer using IEC 61850quality definitions

5. Network architecture

The load-shedding network architectureconsists of IEDs, their functional organizationand their inter-communication.

PML630 performs load-shedding actionsbased on the binary and measurement data itreceives from the IEDs associated withgenerator feeders, grid transformer feeders,motor or load feeders, bus coupler feedersand bus tie feeders. After making a decisionto take load shedding action, the PML630sends shed commands to motor or loadfeeders through their respective IEDs. Dataflow between the IEDs and PML630 isrealized over IEC 61850 GOOSE.

COM600 Station Automation device monitorsand controls the load-shedding operation andsubstation processes. This is realized overIEC 61850 MMS communication betweenCOM600 and PML630 or feeder IEDs.

The integrated system of PML630, feederIEDs and COM600 Station Automation deviceto realize load-shedding power managementsolution is known as cPMS [1]. cPMS is an

8. Communicationarchitecture supportin cPMS

In a cPMS configuration that contains amaximum number of feeders, PML630communicates with 83 feeder IEDs, assumingone IED per feeder, over IEC 61850 GOOSEcommunication protocol and with COM600IEC 61850 client over IEC 61850 MMScommunication protocol.

The feeder IEDs can further be classified intoeight power source IEDs, 15 network circuitbreaker IEDs and 60 load feeder IEDsarranged as independent loads or arranged inload shed groups.

In a redundant configuration, two PML630scan execute the load-shedding functionalityindependently. All feeder IEDs are configuredto communicate simultaneously with bothPML630s over IEC 61850 GOOSE. EachPML630 is connected to its own COM600Station Automation device.

9. System protectionand control functions

Fast load-shedding

The fast load shedding function protects thenetwork during a power deficit. A networkpower deficit occurs when a generator, a gridtransformer, a bus coupler, or a bus tiefeeder circuit breaker trips. The fast load-shedding function can monitor a maximum offour independent power networks. During apower deficit in one of the networks, the IEDperforms power balance calculations andarrives at a sheddable load priority. The IEDissues shed commands to loads with priorityless than or equal to the calculated priority.

The fast load-shedding functionality isexplained here using an example.

GUID-12AE2678-1156-44CD-8158-B3DD33A98CF4 V1 EN

Figure 6. cPMS supported subnetworks

In this substation configuration example,when AB, AC, BD and CD connections areopen, four subnetworks or power networksare formed. The fast load-shedding functionmonitors available power from power sourcesbased on their capability against the powerconsumption and performs power balancecalculation for each subnetwork using theequation:

(ΣPgenerator + ΣPspinning reserve) +

(ΣPgridtransformer + ΣPgrid additional drawal capacity)

≥ (ΣPLoad + ΣPload inhibit (system or manually

inhibited))

Available power from generator = ΣPgenerator

+ ΣPspinning reserve

Available power from grid transformer =

ΣPgridtransformer + ΣPgrid additional drawal capacity

• ΣPgenerator is the total power generated by

the generator(s) in the subnetwork.• ΣPspinning reserve is the total reserve capacity

of all generator(s) in the subnetwork. Thisdepends on the ambient temperature,capability of a generator and its workingmode.

• ΣPgridtransformer is the total power flow from

grid transformer(s) in the subnetwork.• ΣPgrid additional drawal capacity is the total

additional power that can be taken fromthe grid.

• ΣPLoad is the total power consumption of all

load feeders in the subnetwork.• ΣPload inhibit is the total power consumption

from load feeders that do not participate inload-shedding and/or the resultant powerdue to power balance mismatch caused bymeasurement inaccuracies.

The fast load-shedding function performs thefollowing actions in a power network.

• Initiates power balance calculation in apower network on activation of a criticalsignal

• Calculates the sheddable load according tothe priorities using the actual measuredpower value from all feeders and user


ABB 9

defined priority value from PCM600engineering station or from the IED frontpanel user interface (Local HMI or LHMI)I

• Issues load shed commands to load(s) withpriority less than or equal to the calculatedshed priority and discards loads that areinhibited for load shedding (manually or bysystem because of measurementinaccuracies)

• Uses PML630's IEC 61850 communicationinterface module to issue load shedcommand information over GOOSE to loadfeeder IEDs

• Builds subnetwork-wise dynamic loadtables and power network information fordisplay in COM600 Station Automationdevice

PML630 identifies certain events as criticalsignals for initiating the power balancecalculation.

• Opening of generator feeder or gridtransformer feeder circuit breaker

• Opening of bus coupler feeder or a tie line(network) circuit breaker

• Protection-lockout function operation offeeder protection functions

• Lockout function operation of a generatorturbine

Slow load-shedding

The slow load-shedding function reduces theoverload on grid transformers and/or reducesmaximum demand to an acceptable levelbased on the parameters settings. Thesesettings can be defined from PCM600.

This function is activated when a gridtransformer experiences an over loadcondition. The overload detection isperformed based on the IDMT principle,similar to the one implemented fortransformer overload protection.

PML630 requires adequate coordination withgrid transformer feeder IEDs for early overload detection and effective activation of theload-shedding functionality.

Another form of overload detectionimplemented is based on maximum demand

exceeding beyond a certain time limit. Boththe power threshold and time durationparameters are specified using PCM600.

Both the above overload detection methodsgenerate a trigger that is passed onto the fastload-shedding module. It then generates shedcommands to loads, by considering theacceptable reserve value parameter for powerbalance after trigger is generated.

Manual load-shedding

The manual load-shedding function in theIED is activated based on the subnetworklevel. The IED LHMI is used for entering thepriority. This function issues shed commandsto feeder IEDs with priorities less than orequal to the user defined priority.

Load-shedding blocking

The load-shedding blocking feature can beused to block load-shedding functionality.This prevents the fast and slow load-sheddingfunctions from initiating actions whenprovided with incorrect data. Load-sheddingblocking can be achieved automatically ormanually.

Automatic blocking

The load-shedding functions are blockedautomatically during certain subnetworkconditions.

• During a communication failure betweenPML630 grid transformer IED

• When the data from grid transformer IEDhas bad IEC 61850 quality

• When grid transformer IED is in test mode• When the generator or grid transformer

circuit breaker is in intermediate positionfor a time duration longer than 200 ms orin an undefined state

The load shedding functionality is blocked inall subnetworks when the communicationbetween the bus coupler or bus tie feederIED and PML630 fails or when the buscoupler or the bus tie feeder is in anundefined state.


10 ABB

Manual load shedding will not be active in asubnetwork, if the fast or slow load-sheddingin that subnetwork is blocked.

User initiated blocking

User can block fast and slow load-sheddingfunctions in a subnetwork from PCM600 orfrom the LHMI of the IED.

Load feeder inhibition

Load feeder inhibition feature is used toprevent load-shedding functions frominitiating open commands to the inhibitedload feeder. Load feeder inhibition can beachieved automatically or manually.

Automatic load feeder inhibition

Automatic load feeder inhibition is performedduring the following subnetwork conditions.

• When the load feeder IED’s communicationwith PML630 fails

• When the data from the load feeder hasbad IEC 61850 quality

• When the load feeder IED is in test mode,which in turn is reflected also in the IEC61850 quality

• When the load feeder circuit breaker is notin close condition

User initiated load feeder inhibition

The user initiated load feeder inhibition canbe performed from PCM600 or from theLHMI of the IED.

10. Inputs and outputs

GOOSE communication

The fast and slow load-shedding functions inthe IED require a fixed set of data from thefeeder IEDs. This data is sent via IEC 61850GOOSE.

• Generator feeder IED provides real power,circuit breaker status, circuit breaker

service position and protection lock outoperation data.

• Grid transformer feeder IED provides realpower, current, circuit breaker status,circuit breaker service position andprotection lock out operation data.

• Network circuit breaker feeder IEDprovides real power, circuit breaker status,circuit breaker service position andprotection lock out operation data.

• Load feeder IED provides real power andcircuit breaker status data.

Load-shedding functions generate load shedcommand data, which is sent by IEC 61850GOOSE messaging. This information, afterreaching a load feeder IED, initiates theopening of the corresponding circuit breaker.Power source, bus coupler, inter bus tiefeeders and load feeder IEDs send data toPML630 over IEC 61850 GOOSE. Whileanalog values are sent with a slower GOOSEtime cycle of 1000 ms, binary values are sentas spontaneous GOOSE messages withminimum time of 4 ms.

MMS communication

The IED uses IEC 61850 MMS communicationprofile to send load-shedding operationaldata to COM600. This data is displayed in load-shedding displays, alarm or event lists andsubstation single-line diagrams. Using theMMS profile, the IED also receives load-shedding control actions, manual load shedcommand and load-shedding reset commandsfrom COM600.

The IED sends the following load-sheddingoperational data to COM600.

• Fast load-shedding function sends loadshed operation status (after the initiation ofpower balance and load shed prioritycalculations)

• Slow load-shedding function sends gridtransformers (1 or 2) overload, maximumdemand violation, operation status andIDMT or maximum demand based overloaddata

• Manual load-shedding function sendssubnetwork-wise status


ABB 11

• Overall load-shedding function sends also acombined load-shed operation status

• Power network load-shedding data - powerbalance calculation data, load-sheddingblock status, sources, busbar and loadnetwork assignment data, active status ofsubnetwork 1/2/3/4

• Sources data - generator circuit breakerstatus and power, grid transformer circuitbreaker status and power load data

• Network circuit breakers (bus couplers andinterbus tie feeders) data - circuit breakerstatus, power data

• Load data - accumulated load per priorityper busbar, load feeder circuit breakerstatus and power, load feeder priority andload shed inhibit status

COM600 provides the following load-shedding control actions to PML630.

• Fast load-shedding - overall and individualsubnetwork load shed reset command

• Slow load-shedding - IDMT based resetcommand

• Manual load-shedding - subnetwork-wisecommand

Hardwired I/Os

The IED hardwire I/O consists of an analogboard of four current transformer channelsand five voltage transformer channels. Thereare 14 binary inputs and nine binary outputsas part of the communication board andpower supply module respectively. Since theIED receives and sends all data over IEC61850 GOOSE, the load-shedding applicationdoes not use the hardwire analog or binary I/Os. While the analog board is essential forthe functioning of the IED, the binary I/Osare idle by default. However, they can beconfigured and used as required.

11. Disturbancerecording

The disturbance recording function includescollecting information when a load shedtrigger occurs. The numerical disturbancereport can be accessed via the local HMI. Amore comprehensive disturbance report withwaveforms is available using PCM600. TheIED is equipped with a disturbance recorderwith 10 analog signal channels. Out of the 10analog channels, eight channels can be set torecord the waveform of the load-sheddingdata.

• Subnetwork 1 Available Power• Subnetwork 1 Load• Subnetwork 2 Available Power• Subnetwork 2 Load• Subnetwork 3 Available Power• Subnetwork 3 Load• Subnetwork 4 Available Power• Subnetwork 4 Load

A power source outage or opening of anetwork circuit breaker generates aninternally generated binary event that ismapped in the IEC 61850 model of the IEDas load-shed start signal. The recording fromthe analog signal channels of disturbancerecorder is triggered by the load-shed startsignal. This indicates the initiation of powerbalance calculations.

Initiation of power balance calculations donot imply the operation of the fast or slowload-shedding function, since it depends onthe available power in the subnetwork. Anegative power deficit due to a power source


12 ABB

outage in the power network or opening of anetwork circuit breaker activates PML630 toissue load-shedding commands.

The disturbance recorder function providesthe value of available power and load in eachsubnetwork before and after the load shedcalculation initiation. This is helpful inascertaining the power situation in thesubnetworks before and after a load shedstart event.

The disturbance recorder can store up to 100recordings in the non-volatile memory. Theserecordings can be uploaded for subsequentfault analysis. The number of recordingsdepend on the length of the recording andthe number of incorporated signals.

The disturbance recorder and the Start LEDon the front-panel IED user interface are bothactivated by the load-shed start signal. Theload-shedding function start signal at state 1is configured to activate the Start LED.

12. Event log

The IED features an event log which enableslogging of event information. The event logcan be configured to log informationaccording to user pre-defined criteriaincluding IED signals. To collect sequence-of-events (SoE) information, the IEDincorporates a non-volatile memory with acapacity of storing 1000 events withassociated time stamps and user definableevent texts. The non-volatile memory retainsits data also in case the IED temporarily losesits auxiliary supply. The event log facilitatesdetailed pre- and post-fault analyses of faultsand disturbances.

The SoE information can be accessed locallyvia the user interface on the IED front panelor remotely via the communication interfaceof the IED. The information can further be

accessed, either locally or remotely, using theweb-browser based user interface.

13. Self-supervision

The IED’s built-in self-supervision systemcontinuously monitors the state of the IEDhardware and the operation of the IEDsoftware. Any fault or malfunction detected isused for alerting the operator.

Self-supervision events are saved into aninternal event list which can be accessedlocally via the user interface on the IED frontpanel. The event list can also be accessedusing the web-browser based user interfaceor PCM600.

14. Access control

To protect the IED from unauthorized accessand to maintain information integrity, the IEDis provided with an authentication systemincluding user management. Using the IEDUser Management tool in the Protection andControl IED Manager PCM600, an individualpassword is assigned to each user by theadministrator. Further, the user name isassociated to one or more of the fouravailable user groups: System Operator,Protection Engineer, Design Engineer andUser Administrator. The user groupassociation for each individual user enablesthe use of the IED according to the profile ofthe user group.

21. Tools

PML630 is delivered without factory made pre-configuration. The default parameter settingvalues can be changed from the front-paneluser interface, the web-browser based userinterface (WebHMI) or the PCM600 tool incombination with the IED specificconnectivity package.

PCM600 offers extensive IED configurationfunctions such as IED applicationconfiguration, signal configuration, DNP3communication configuration and IEC 61850communication configuration includinghorizontal communication, GOOSE.

When the web-browser based user interfaceis used, the IED can be accessed eitherlocally or remotely using a web browser (IE7.0 or later). For security reasons, the web-browser based user interface is disabled bydefault. The interface can be enabled withthe PCM600 tool or from the front panel userinterface. The functionality of the interface isby default limited to read-only, but can be

configured to enable read and write access bymeans of PCM600 or the local HMI.

The IED connectivity package is a collectionof software and specific IED information,which enable system products and tools toconnect and interact with the IED. Theconnectivity packages reduce the risk oferrors in system integration, minimizingdevice configuration and set-up times.

The configurability of the IED ensures easyadaptation of load-shedding functionality toyour industrial power network, thus fulfillingthe specific requirements of the presentapplication. PCM600, which is used toconfigure the feeder IEDs is also used toengineer PML630. An efficient and effortlessengineering procedure eliminates the re-entering of power network data and ensuresthat the following engineering steps arecompleted automatically.

• Instantiation of function blocks and theirinterconnections

• Generation of the load shedding single-linediagram for local HMI

• IEC 61850 engineering and GOOSE signalmapping, specific to the IED

• Load-shedding display configuration forCOM600 HMI

PML630 Connectivity Package offers severaladditional features for engineering a cPMSsolution conveniently. These features includeload feeder templates for load shed commandhandling, standard parameter set and asample reference project.

22. Supported ABBsolutions

The cPMS solution seamlessly integrates thePower Management and SubstationAutomation functionality using the load-shedding network architecture.

To facilitate and streamline the systemengineering, the IEDs are supplied withconnectivity packages containing acompilation of software and IED-specificinformation including single-line diagramtemplates, a full IED data model includingevent and parameter lists. By utilising theconnectivity packages the IEDs can be readilyconfigured via the PCM600 Protection andControl IED Manager and integrated with theCOM600 Station Automation device.

Compared with traditional hard-wired inter-device signaling, peer-to-peer communicationover a switched Ethernet LAN offers anadvanced and versatile platform for powersystem protection. Fast software-basedcommunication, continuous supervision ofthe protection and communication system,and inherent flexibility for reconfigurationand upgradation are among the distinctivefeatures of the protection and automationsystem approach.
