배전계통 신뢰도 향상을 위한 자동화 개폐기 투자우선순위 결정에 관한 연구

The change of manual switches to automatic switches to a distribution feeder does, in general, increase reliability by decreasing the duration of the outage of many to the customers on the feeder. But, the distribution system has complex load patterns. Therefore, we should decide to changing of switch, which is the first. In this paper, we evaluate the effectiveness of a switch installation and decide the replacement sequence for reducing outage cost.
