摘　　要：提出了一种基于区段两端零模电流值乘积积分的高速铁路电力贯通线故障定位方法.该方法借助现有铁路远动系统,仅需要每个区段终端FTU上的零序电流值,即可快速准确定位故障区段.数字仿真试验结果表明:该方法不受故障距离、配变负载及过渡电阻的影响,且对FTU数据采集的采样率和同步性有良好的适应性.This paper puts forward a new method used in high speed railway power supply line based on the integral of zero-mode current on both ends of the section. This method relies on railway remote control system,which only needs the zero sequence current on each terminal FTU section and could pinpoint the fault section quickly. Digital simulation results show that the proposed method is not affected by the fault distance,distribution of load and the transition resistance,and have a good adaptation for the sampling rate of the data acquisition and synchronization.
