瞬時電圧低下におけるガスエンジン発電機保護装置の開発

Abstract

In recent years, th e electric power system becomes more and more complicated. Therefore, the supply of electric power with stability and high reliability is required. Transmission line fault gives the distributed influence by instantaneous Voltage Drop and the over-current. Therefore, this paper is describes on the instantaneous voltage drop phenomenon in the power system that distributed generator was introduced. Equipment such as DVR and FCL is developed in order to cope with this problem. The examination was carried out by computer simulation in respect of the instantaneous voltage drop phenomenon.
