摘　　要：利用配电网量测量相关性提出了配电网故障定位的新算法,即以配电网量测电流间的相关性得出缺失的故障信息,并用故障判定矩阵进行故障定位,对某些节点处没有配置FTU或因FTU故障而不能得到该节点信息的配电网络进行了故障定位研究,算例分析表明该方法是可行的。该方法有效地解决了由于FTU(现场终端设备)故障、FTU数量不足等原因所导致的故障信息不足的问题。By using the measurement correlation of power distribution network,a new algorithm is put forward for fault location in power distribution network.The fault information lack comes from the correlation of distribution network measurement current.The paper discusses the algorithm which distribution network nodes have no FTU or have no information as to FTU fault.Example analysis shows that the method is feasible.This method can effectively solve the problem of shortage of the fault information,such as the FTU(feeder terminal unit) fault,insufficient information about FTU.
