EUB Current and voltage transformers

EUB Current and voltage transformers

A wide spectrum of current and voltage transformers are used for various requirements in electrical powerengineering. The experiments include a practical hands-on investigation of transfer response, over-current factor,absolute and phase angle error, as, for example, under varying loads. In addition to this, standard operationrequirements, short-circuit and asymmetrical faults can also be explored.

The protection of system facilities and components is not only dependent on selective protection equipment butalso on the detection and measurement of the lowest fault currents and voltages. Various types of measurementcircuits have to be used for different star-point circuit configurations in order to correctly detect and localisepotential fault types.

Power generation

Power generation

Three-phase synchronous generatorsIn addition to the basic experiments on three-phase synchronous generators, the experiments in this area alsocover manually-operated and automatic synchronisation circuits as well as automatic power factor control (cos-phi control) and power control. For that reason, this module can be used to simulate both on-grid and off-gridpower plant operation. Furthermore, generators need effective protection against internal and external faults. Thedeployment of a variety of protective equipment is a prerequisite for this.


EUG Generator control and synchronising circuits


Electrical power is mainly produced by three-phase generators. This applies to power stations as well as tostandby power supplies and wind generators. In addition to the basic experiments dealing with three-phasesynchronous generators, the experiments involving the "EUG" module include manual and automaticsynchronising circuits as well as experiments on the automatic power factor control (cos-phi control) and powercontrol. Thus, the ”EUG“ module can be used to simulate power station operation in stand-alone (isolated) orinterconnected operation.

EGP Generator protection

EGP Generator protection

Effective protection of generators against internal and external faults requires that a wide variety of protectivedevices be deployed.

Generator differential protection covers the internal faults like short-circuit fault, interturn and interwinding faultsor phase-earth-phase faults and serves as the primary protection.

The time overcurrent protection constitutes the reserve protection for the generator and can also be used for thedetection of external faults, such as short circuits and overload, for example. Earth-fault occurrences aredetected with the stator-earth fault protection. The investigation of reverse power and unbalanced load protectionas well as overvoltage/undervoltage protection concludes the experiment series titled “EGP“ on generatorprotection.

Transformers

Transformers

In power engineering, transformers are used to connect the various voltage echelons of the power grid to eachother. In transformer stations, electricity from the regional distribution grid with a medium voltage level of 10 to36 kV is transformed to supply power to low-voltage end customers in the local grid. The heart of a transformerstation is the transformer itself which also requires protective equipment. By carrying out hands-onmeasurements and fault simulations with the training system, it is possible to gain an understanding of thesecomplex systems in the classroom.

ETP Transformer protection

ETP Transformer protection

Differential protection for transformers (starting from approx. 1 MVA), combined with time overcurrent protection,can be investigated using measurement techniques in normal operation, fault occurrences in various windingcircuit configurations (star, delta), in various vector groups and as a function of star-point treatment (floating,direct or earthed using earth coils). In the case of differential currents, the tripping criteria is determined basedon characteristic sensitivity.

The time overcurrent protection supplements the safety protection measures contained in transformer differentialprotection. It protects the transformers against short circuits outside the protection range and againstoverloading.

Power transmission

Power transmission

High-voltage networks are usually operated with voltages in the region of 110 kV to 380 kV, whereby urban areasand large-scale industrial facilities are supplied with 110 kV, and 380 kV is used for long-distance transmissionlines. The line simulation system is designed for operation at model voltages between 110 V and 380 V. Variousvoltage levels and line lengths can be selected via corresponding overlay masks. Examinations with the trainingsystem can be performed off-load, in normal operating mode, in the presence of a short-circuit or earth fault, withor without earth-fault compensation. The system also permits assembly of complex networks by connecting theline simulation models in parallel or series. The voltage can be supplied via a fixed grid or synchronousgenerator.


EUL High-voltage transmission lines


For your safety, this investigation of 380-kV and 110-kV transmission lines and how they are connected togetheris carried out using low voltage, but without losing the actual properties of genuine high-voltage lines. Theserealistic simulations of a 380-kV transmission line and a 110-kV cable link are automatically switched betweendifferent line lengths once the appropriate overlay mask is put in place. By using simulations of various linelengths, it is possible to assemble complex transmission networks.Earth-fault compensation in electric power supply networks is designed to offset earth leakages occurring inouter conductors.

Restricted to three-phase systems, earth-fault compensation makes use of a special Petersen coil named afterits inventor and which is also known as an earth-fault quenching coil. This coil compensates the electric currentat the earth-fault point, thereby preventing consequential malfunctions in the electrical system.The objective here is to measure characteristic power transmission parameters on simulated, three-phase,parallel-connected lines fed via a fixed network or a generator, and perform quantitative as well as qualitativeassessments of operational relationships.

EDC1 High-voltage direct current transmission (HVDC)


Sustainable energy transmission for efficient and reliable grids in the future

High-voltage DC transmission is a method for transmitting electrical energy by means of high DC voltage.This technique is intended for the long-distance bulk transmission of energy via DC, since above certaindistances HVDC exhibits a lower degree of loss overall than is the case for conventional transmission usingthree-phase AC power, in spite of the increased converter losses.High-voltage DC transmission is frequently used for energy transmission over comparatively short distances aswell if the electrical transmission line has been designed with a high degree of capacitance. This is the casewith maritime cabling but also buried terrestrial lines.One other application is for an intermediate coupling link between networks, which allows for direct exchange ofelectrical energy between three-phase power networks.

Training objectives:

Control of intermediate circuit voltageProvision of reactive power but with no effect on the flow of active power (STATCOM)Manual and automatic synchronisation with the electric power gridControl of HVDC reactive power with modification to the flow powerIndividual control of reactive power for both converter stationsObservation of losses for various lengths of HVDC linesProvision of a power network with passive consumers by means of HVDC (black start)Coupling of wind turbinesInvestigation of fault ride-through (FRT) behaviour in HVDC systems

Electric power distribution


Electrical power at large switching stations is distributed almost exclusively using double busbar systems.

These stations incorporate switching matrices for connecting the two busbars, the incoming and outgoing feedercubicles as well as the measurement fields. The incoming and outgoing feeder cubicles as well as the switchingmatrices are furnished with circuit breakers and one disconnector for each busbar terminal. For safety reasons,a particular switching logic must be strictly adhered to here. The double busbar model incorporates all functionsof practical relevance. Integrated instruments for measuring currents and voltages permit direct analyses ofswitching operations.

Energy management

Energy management

For economic and environmental reasons, a rational use of energy is becoming increasingly important.Exercises on manual and automatic compensation of reactive power as well as experiments on reducing peakloads through measurements with active-current and maximum-demand meters demonstrate how the load on anelectricity supply network can be reduced and evenly distributed over a 24-hour period. An analysis of the powersupply grid and connected consumers (loads) is necessary for effective use of the involved measurementtechniques. Accordingly, each experiment permits a detailed investigation of static, dynamic, symmetric andasymmetric loads. Protection of electrical consumers is another important training subject.


EUC Energy management

EUC Energy management

Experiments on reducing peak loads through measurements with active-current and maximum-demand metersdemonstrate how the load on an electricity supply network can be reduced and evenly distributed over a 24-hourperiod. An analysis of the power supply grid and connected consumers (loads) is necessary for effective use ofthe measurement techniques involved. Accordingly, each experiment permits a detailed investigation of static,dynamic, symmetric and asymmetric loads.

In this case, a three-phase asynchronous motor coupled with the servo machine test stand is used as adynamic load. The active and reactive power (cos-phi for the motor) depend on the motor load and are thereforenot constant. The servo machine test stand can be used to drive the asynchronous motor, thereby feeding activepower into the three-phase network.

Reactive power compensation in alternating voltage networks is designed to reduce undesirable reactive currentand resulting reactive power at the consumers. In this process, capacitive loads are connected to all inductiveloads via a central feed point. The opposing, capacitive reactive power arising here is ideally of the samemagnitude as the installed, inductive reactive power. This reduces undesirable reactive currents and none of thesystems needed to supply the reactive current has to be of excessive size.

For safety reasons,a particular switching logic must be strictly adhered to here. The double busbar model incorporates all functionsof practical relevance. Integrated instruments for measuring currents and voltages permit direct analyses ofswitching operations.

Transmission lines

For your safety, the 380kV transmission lines are investigated and connected at a low-voltage level withoutdetracting from the characteristics of a real high-voltage line. This realistic simulation of a 380-kV transmissionline switches over automatically between line lengths of 300 km and 150 km (93.2miles and 186.4miles) oncethe overlay mask has been put into place. Joint use of several line simulation models connected in parallel orseries permits complex networks to be assembled.

Line protection

In practice, medium-voltage and high-voltage networks are equipped with protective mechanisms connected viacurrent and voltage transformers.

The equipment set offers the following benefits

Use of compact, original relays incorporating cutting-edge digital technologyUse of industrial safety relays from prestigious international manufacturersMonitoring of protective features by means of SCADA (Supervisory Control and Data Acquisition)A relay test option permits the relays to be checked individually

Investigating complex loads

Experiments on reducing peak loads through measurements with active-current and maximum-demand metersdemonstrate how the load on an electricity supply network can be reduced and evenly distributed over a 24-hourperiod. An analysis of the power supply grid and connected consumers (loads) is necessary for effective use ofthe measurement techniques involved. Accordingly, each experiment permits a detailed investigation of static,dynamic, symmetric and asymmetric loads.

In this case, a three-phase asynchronous motor coupled with the servo machine test stand is used as adynamic load. The active and reactive powers (cos-phi for the motor) depend on the motor load and are thereforenot constant. The servo machine test stand can be used to drive the asynchronous motor, thereby feeding activepower into the three-phase network. Reactive power compensation in alternating voltage networks is designed toreduce undesirable reactive current and resultant reactive power of consumers. In this process, capacitive loadsare connected to all inductive loads via a central feed point. The opposing, capacitive reactive power arising hereis ideally of the same magnitude as the installed, inductive reactive power. This reduces undesirable reactivecurrents, and none of the systems needed to supply the reactive current has to be over-dimensioned.

Electrical power is mainly produced by three-phase generators. This applies to power stations as well as tostandby power supplies and wind generators. In addition to the basic experiments dealing with three-phasesynchronous generators, the experiments involving the "EUG" module include manual and automaticsynchronising circuits as well as experiments on the automatic power factor control (cos-phi control) and powercontrol. Thus, the ”EUG“ module can be used to simulate power station operation in stand-alone (isolated) orinterconnected operation.

Sustainable energy transmission for efficient and reliable grids in the future

High-voltage DC transmission is a method for transmitting electrical energy by means of high DC voltage.This technique is intended for the long-distance bulk transmission of energy via DC, since above certaindistances HVDC exhibits a lower degree of loss overall than is the case for conventional transmission usingthree-phase AC power, in spite of the increased converter losses.High-voltage DC transmission is frequently used for energy transmission over comparatively short distances aswell if the electrical transmission line has been designed with a high degree of capacitance. This is the casewith maritime cabling but also buried terrestrial lines.One other application is for an intermediate coupling link between networks, which allows for direct exchange ofelectrical energy between three-phase power networks.

Training objectives:

Control of intermediate circuit voltageProvision of reactive power but with no effect on the flow of active power (STATCOM)Manual and automatic synchronisation with the mainsControl of HVDC reactive power with modification to the flow powerIndividual control of reactive power for both converter stationsObservation of losses for various lengths of HVDC linesProvision of a power network with passive consumers by means of HVDC

In this experiment the response of a three-phase variable transformer connected up as an autotransformer isinvestigated operating in conjunction with a power transmission line model including connected load. Due to theenormous increase in photovoltaically generated electricity being fed to the low-voltage power grid, in someareas there is a lot of fluctuation under changing conditions of sunlight and loading. Such fluctuations can becompensated for with the help of a controllable local grid.Training content:

"Micro Grid Trainer" - Control of stand-alone networks

"Micro Grid Trainer" - Control of stand-alone networks

A stand-alone power network is a type of power supply network which is closed and has no active lines couplingit to other parts of the electrical power supply grid. A stand-alone network is markedly smaller than a combinedelectricity grid and does not usually incorporate high-voltage power lines. For this type of network there are twodistinct modes of operation, stand-alone mode and isolated parallel or generator-to-generator operation. Thistype of supply network is frequently used for the industrial power supplies of large businesses. When this stand-alone network is connected to a smart grid, it is referred to as a microgrid. This type of grid has three differentoperating modes: on-grid, off-grid and dual mode. Microgrids will be playing a huge role in the smart grids oftomorrow. A microgrid features the following benefits:

Transmission and transformer losses are reducedMore independence from major power suppliersSmart grid act as a back-up systemIntelligently controlled power supply and consumption thanks to SCADAPower generation using renewable energy sourcesOptimizing the quality, reliability and sustainability of electricity
