설비의 고장을 데이터를 이용한 변전소 신뢰도 분석 연구

The most crucial requirement of a power system is to supply quality electric energy to customers without interrution, this problem is directly related to reliability of power system. Reliability assessment of power system has been an important topic for the past several decades. This paper deals with reliability assessment of a 154㎸ power substation in KEPCO. In this paper, exponential distribution is used to calculate reliablity index. The failure rate data that are utilited for reliablity index based on the realistic system. Also, FTA(Fault Tree Analysis) is used to compute substation reliablity
