Development of Circuit Breaker Model and Induction Machine Model for Power System Simulator

Abstract

Real time analogue simulator is useful for analysis of power system phenomena and for performance test of controller and protection equipment in power system. Large scale simulator and high precision simulator have been developed in recent years. Authors have developed two models which are required to realize a high precision simulator. One is a new circuit breaker model with loss compensation circuit that contributes loss suppresion in the simulator circuit. The other is an induction machine model which makes load characteristics closer to one in actual power systems. The induction machine model is a newly designed voltage output type and operates in stable that is composed by analogue circuit.
