A Fault Section Detection Algorithm to use ZCT in Ungrounded Distribution Network

ZCT를 이용한 비접지계통에서의 사고유형별 사고구간 검출 알고리즘

In this paper, a fault section detection algorithm to be considered variety measurement devices is proposed in ungrounded diatribution network. Ungrounded network is different from grounded netork. It's that a fault current doesn't generate when a single grounded fault by characteristic of ungrounded network. So, a fault section detection is very difficult. Thus, in this paper, a fault section detection method is proposed by data from variety measurement devices. The method is proved by matlap simulink.
