摘　　要：利用电流的连续性提出了故障定位的新判据 ,即以故障电流是否连续为故障定位的判据 ,故障电流非连续的区域就是故障区域 ,并用故障判定矩阵进行故障定位。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 ,完全可以满足在线应用的需要。According to the continuity of the current, a new criterion for fault location in distribution system is formed. The criterion is whether the current is continuous. That is: The zone within which the current is not continuous is the fault zone, and then the fault zone is identified with the fault judgement matrix. The algorithm effectively resolves the fault location in the case of lack of the fault information, and the algorithm is designed for on line application.
