Advanced power system analogue simulator

The authors describe the development technology and performance test results of an analog simulator designed to analyze continuous phenomena ranging from transient to steady state in a large-scale power system. The simulator is a large-scale system with a total of approximately 500 units, including 30 generators, 304 transmission lines, and 20 loads, HVDC transmission facilities and static VAR compensators. It uses unique models. The generator model can simulate a synchronous machine, an induction machine, and an adjustable speed pumped-storage machine. The load model can simulate voltage characteristics with load dynamics. It uses a high-performance man-machine interface. This lets the operator input network configuration data through a system diagram image from the workstation, and control system data through a block diagram. It uses an automatic network configuration system. Performance testing performed by the Kansai Electric Power Company is discussed
