Simulation of Operating Condition of the Equipment of the Short-Circuit Generator Package

For testing of high-capacity power electrical equipment, it is necessary to use short-circuit turbine generators operating in combination with auxiliary equipment: excitation system, variable frequency drive with induction motor, oil supply system for generator-motor unit, in-process monitoring and control system. As the operating conditions are considered to be very heavy in dynamic and temperature influence, in response time, the equipment comprising short-circuit generator package shall be designed and manufactured different to conventional ones. The simulation is performed to make analysis of capability and sizing of short-circuit generator package equipment especially excitation system. The article describes results of simulation and requirements to the equipment to fulfill necessary testing and provide reliable operation.
