行波法故障测距在不同类型接触网中适应性研究

牵引供电系统作为列车的动力来源,其稳定性至关重要。随着接触网结构越来越复杂,牵引供电系统故障测距难度也越来越高。本文从传统故障测距原理出发,引入行波法故障测距,对比行波法与传统阻抗法,行波法故障测距具有良好的适应性与稳定的测距精度,是未来接触网故障测距主要发展方向。

For the traction power supply system,a power source of the trains,its stability is most important.Along with the increasing complexity of OCS structure,fault location of traction power supply system become more and more difficult.Starting from the principle of traditional fault location,the paper introduces the traveling wave method for fault location,and after comparison of traveling wave method with the traditional impedance method,the traveling wave method for fault location has good adaptability and stable location accuracy,it is the main development direction for fault location of OCS.
