MV1305 Mobile Motor / Generator Unit

MV1305-405 Mobile Motor / Generator Unit A standard laboratory for power transmission normally consists of one or two generators, which are connected to one or more transmission links which finally reach transformers, distribution units and loads. This configu-ration may look like the very left line in figure 1.However, a realistic network most likely looks like the complete network of figure 1. For example, here can be seen turbine/generators in parallel on the same busbar, a synchronous machine used as a synchronous com-pensator in the middle of a line, a single generator unit and a heavy group of generators.Energy transfer, load shedding, static and dynamic sta-bility at disturbances as well as sophisticated protection schemes can be studied under realistic forms. Not to forget compensation possibilities.Power- and current- paths in grid networks are compli-cated. The TERCO system will give understanding for this problem. The wide range flexibility will be given by the mobile generator station / synchronous alternator (compensa-tor) MV 1305.Two sets of MV 1305 can operate as described or work in parallel. In this case mechanical and electrical pa-rameters might be changed by using e.g. flywheel (MV 1010) and different electrical connections.

Modes of OperationA. Control of active power (frequency): AC-machine

and frequency converter drive (”turbine”) + synchro-nous machine (generator) in closed loop connection regarding frequency.

B. Control of active power (frequency) and reactive power (voltage): Two closed loops regarding fre-quency and voltage.

C. Synchronous compensating: AC-machine and fre-quency converter drive (”turbine”) idling, electrically disconnected or mechanically disconnected, syn-chronous machine in closed loop connection for volt-age (=reactive power) control.

Technical Specification Power Supply: Voltage 380-415 V AC 3-phFrequency 50 HzMax current 16 A

GeneralTERCO Power Factor Controller (PFC) is also a module within our Classical electrical Machine Program.

With the PFC you can minimise the currents caused by reactive losses of power and thereby optimising the transfer of energy between generation and loading.

This is becoming more and more important today when “Saving energy” is vital in a world with focus on pollution and shortage of energy.

Field of applicationInductive or mixed inductive and resistive networks in need of compensation, for example when starting and running induction motors.

Principles of operationDepending on the power factor of the loading network a microprocessor will connect groups of capacitors.By measuring phase voltages and current the micropro-cessor will calculate how many capacitive groups that has to be connected and also in which combinations.

Electrical detailsNumber of 3-ph groups 6 Power factor setting 0.7 inductive to 0.7 capacitiveNominal voltage 3 x 400 V 50 – 60 Hz Code no. MV 1439-405

Nominal power 0 – 2 kVAr cap.PF-Controller Automatic or manual Adjustable delay times, switching sequences and strategies.

Monitoring and Measurement on the controller: Voltage, Current and Power factorSwitching modes: Linear and circularIndication lamps: Indication lamps for the capacitor groups which are connected

Physical designThe Power Factor Control Unit is housed in a sturdy apparatus box with a clear mimic diagram explaining how to connect the supplying net from the left to the right side where the network in need for power factor compensation is connected.Readings, parameters and sub parameters are indicat-ed on the front of the controller. Other settings and pro-gramming than the defaults are simply performed from the keyboard and displayed on the controller front.

General data:Power supply 1-ph 220 - 240 V, 50 - 60 HzDimensions 510 x 570 x 280 mmWeight 24 kg

Typical Experiments with Terco PFC:• The concept of active power, apparent power and reactive power• The concept of power factor and “cos”• The concept of measuring methods• Start current settings (C/k)• Delay times • Efficiency and losses• Linear and circular switching modes• PF-Controller design and schematics • Programming the controller• PF-Controller and resistive/inductive loads• PF-Controller and induction motor loads• Control range limits

MV1939 Power Energy Meter is a practical solution for the study of 3-Phase AC power systems. A microprocessor-based energy meter provides the user with an instant overview of the relevant three or four-wire, 3-Phase network parameters in balanced or unbalanced networks.

The simplified connection process means your labora-tory experiments can be set up and taken down in just minutes, leaving more time to investigate and under-stand the characteristics and ambiguities of 3-Phase power networks.

Each line is fused with a 500V, 10A slow fuse and together with 10:1A current transformers provide a good level of protection against incorrect connection, mishan-dling and carelessness.

MV1939 Power Energy Meter

The TERCO MV1939 Power Energy Meter enables the measurement and visualisation of 46 power energy quantities and 25 harmonics for each phase of current and voltage. The analyser can display parameters of interest in the study of symmetrical as well as non-sym-metrical networks, such as: phase voltages, phase-to-phase voltages, line currents, phase active powers, phase reactive powers, phase apparent powers, phase active power factors, phase reactive/active power fac-tors, mean three-phase voltage, mean phase-to-phase voltage, mean three-phase current, three-phase active, reactive and apparent powers, mean three-phase power factors.

The visualization of parameters is distributed over programmable pages (max 20 pages) where each page simultaneously displays four parameters.

Developing and coming options

SCADA SystemThe Terco PTG SCADA module includes an advanced and stylish industrial standard HMI where measurement data from throughout the power system is collected, logged and presented.

Power system characteristics can be monitored and investigated in real-time on attractive virtual instru-ments. Time-lapse data tracked and presented clearly in trend charts and values stored in the data logger can be saved and exported for further investigation at a later date.

Clear indications of important system events help oper-ators to understand the complicated relationships and balance required between modern components, in order to maintain a robust power supply.

The Terco PTG SCADA module is designed to work with multiple MV1939 Power Energy Meters. These measurement instruments provide information of over 30 3-phase parameters each and are connected via a MODBUS network.

The HMI can even be accessed and controlled remotely from a PC via a standard web browser. This allows for further presentation via projector, large-screen t.v. or other device.
