为实现非健全故障信息下配电网的快速容错故障定位，提出在终端开辟空间储存采集的三相电流信息，并上传主站。故障后，主站利用配电网故障后各馈线开关上报的遥信量各相故障报警信号之间，遥测量三相故障电流之间以及三相故障电流与各相故障报警信号之间的相关性，对终端设备上报的存在漏报、误报的故障报警信号进行修正。然后，提出通过分析配电网的拓扑结构，将配电网划分为独立的最小配电区域，并提出了综合最小配电区域端点上报的校正后的故障报警信号，快速实现故障区段定位的方法。结合具体实例对所提算法进行了详细的说明，分析表明该算法能有效校正漏报、误报的故障报警信号，快速实现配电网故障区段的容错定位。

In order to realize robust fault location and isolation of distribution systems under the condition of incomplete information, this paper proposes using the relevance among each phase of fault information, three-phase fault currents and both reported by each feeder switch after fault to amend the omitted and false fault information reported by terminal equipment. And then, a method is proposed to achieve rapid fault location of distribution system’s fault section by analyzing the topology, dividing the system into independent minimum distribution area and combining the corrected fault information reported by the above minimum distribution area. The simulation results show that the algorithm can effectively correct the missing and false fault information in order to achieve rapid fault-tolerant location of distribution system’s fault section.
