摘　　要：行波法测距是近年来常用的一种测距方式。本文在介绍故障时波过程的基础上,对行波法测距进行了扼要的分析,并对由于行波法测距出现的问题而引入的基于小波变换技术的行波法测距进行了简要的描述,并对其在江西电力系统应用状况进行了初步分析。ranging with traveling wave is a kind of common method used in power system. Based on the knowledge of the process of the traveling wave during the fault, the analysis is given on the ranging with the traveling wave. With the problems that may happen, the paper also gives the introduction of the ranging for the traveling wave with the wavelet transform and the application in the JiangXi electric power system.
