大規模電力系統故障時における電源制限のための過渡安定度シミュレーション

Abstract

In recent years, complication of power system is progressing. Under such a situation, measures for high-speed stabilization are needed in order to prevent beforehand that the influence of the fault spreads for the whole system. If the fault occurs in power system, improvement in transient stability is expected by carrying out of generator shedding, i.e. some generators are separated temporarily. In this paper, the estimation system of transient stability is built by artificial neural network applicable at the fault occurrence of N-swing step out and is confirmed its effectiveness.
