在配电系统发生故障后，如何快速进行故障定位是研究热点，而利用线路终端(FTU)或故障指示器(FPI)是实现故障定位的主流方法。文章提出的算法基于具有通信功能故障指示器，凭借指示器自动上报的故障信号，采用多步骤单相遍历，对故障线路的电源点和开断点进行追溯，同步比对实时数据，能够较为快速准确地找到故障点和疑似故障点。该算法已在国网浙江省电力公司得到了较好的应用。

When there is a fault in power distribution system, how to quick locate the fault is the research hotspot. And the method of feeder terminal unit (FTU) and fault passage indicator (FPI) has been the main methods. A optimization algorithm based on automatic fault signal by FPI with communication function, which applies multi-step single-phase traversal algorithm, traces back to the power resource and break point of fault line, and compares the real-time data synchronously, was designed to located the fault point accurately. The algorithm was applied in State Grid Zhejiang Province Electricity Power Corporation.
