高压输电线故障定位方法研究

高压输电线路故障定位是保障电网安全运行必要的手段。通过故障定位技术发展历史的介绍，详细地描述了各种故障定位方法的原理、优缺点和应用情况。对两大类故障测距方法，工频量法和行波法进行比较，提出了线路故障定位今后研发的建议：开发的重点放在双端或多端测距新算法上，解决算法的适应性、抗干扰能力和剔除计算伪根等诸多问题。

Study on Fault Location of HV Power Transmission Line

HV power transmission line fault location is a necessary measure to maintain safe operation of power network. Through the introduction of the development history of this technique, the principles, applications, advantages and shortages of several kinds fault location methods are described in detail. Comparing the location basing on power frequency quantities and that of traveling wave, opinions on future development of fault location is proposed： It should emphasize the study on two-terminal and/or multi-terminal algorithm, their ability of adaptation, anti-interference and false root rejection.
