摘要电力电缆承担着电能输送的重任,电力电缆故障的发生严重影响着电力能源的正常供应。如何快速准确地发现故障、确定故障位置是电力电缆维护的重点问题。近年来,电力电缆的行波故障定位法得到快速发展,其中基于小波变换的电缆故障定位法优势最为明显。本文根据电缆故障特点,利用Matlab软件建立了电力电缆故障行波定位模型,实现了故障在线定位,具有一定的应用价值。

Abstract：The power cable bears the responsibility of power transmission. The failure of power cable seriously affects the normal supply of electric energy. How to find fault and locate the fault quickly and accurately is the key issue of power cable maintenance. In recent years, the method of traveling wave fault location for power cable has been developed rapidly, and the advantages of the cable fault location method based on wavelet transform are most obvious. According to the characteristics of cable faults, a location model of power cable fault traveling wave is established by using Matlab software, which realizes the on-line location of faults and has certain application value.

Key words： power cable fault location wavelet transform
