铁路电力系统的正常运行影响铁路运行安全,快速准确定位故障点对于增强铁路供电可靠性,减少经济损失具有重要意义。此文介绍了10 kV铁路自闭/贯通线路的特点及其故障测距技术的研究现状,分析了自闭/贯通线路的结构,阐述了在铁路中应用行波法进行故障测距的特殊性,基于D型双端原理,提出了利用故障时产生的电压行波信号线模分量进行故障测距的方法,并介绍了在线路末端使用TV来获取电压线模行波信号,实现了铁路自闭/贯通线路中故障的快速有效定位。
Abstract：The normal operation of railway power system affects the safety of railway operation,it is of great significance to quickly and accurately locate the point of failure for improving the reliability of railway power supply and reduce economic losses.This paper introduces the characteristics of the line and the research status of the fault ranging technology of 10 kV railway automatic blocking and continuous transmission lines,analyzes the line structure of the automatic blocking and continuous transmission lines,and expounds the particularity of the fault ranging technology by using the traveling wave method in railway.This paper introduces the method of fault ranging method based on D-type double-end principle and by using the aerial mode component of the voltage traveling wave signal when the fault is generated,and introduces the method of using PT to obtain the voltage mode traveling wave signal at the end of line and to achieve fast and effective positioning in the railway automatic blocking and continuous transmission lines.
