An Object Based Graphical Simulator for Power System Protection

객체지향 송전계통보호계전 그래픽 동작 시뮬레이터

When the faults occur in power systems, the protective relay plays a roles of protecting power systems. It is important that the protective relay have high selectiveity and sencitivity performance in power system by correct setting the relays. This paper proposed a testing methods if the reliability of digital relay as simulating the response of relay at faults in the real power system operation environment.
