Current State and Prospects on the Traveling Wave Fault Location of Transmission Line

针对阻抗定位法所存在的问题,回顾了高压输电线路行波测距装置的发展历史,介绍了目前国内研究进展。讨论了目前的故障测距装置中的传感器、高速数据采集、GPS同步单元等几个关键部分的研究情况,同时也对它们今后的发展与改进提出了自己的看法。根据现场调研的情况对装置在实际运行中遇到的一些问题进行了总结,并给出了解决办法。同时也对输电线路行波故障定位装置的发展提出了建议与展望。

To the weakness of resistance fault location method, the history of traveling wave fault location on high voltage transmission line is reviewed. The development of modem traveling wave fault location, the key parts of fault location system, such as sensor, high speed data collection and GPS unit etc., are presented. The problems encountered in real operation are summarised according to field investigation and the solution ways are supplied. The paper also give suggestions and perspects of traveling wave fault location in transmission line.
