摘要
综合阻抗法和行波法两种测距方法的优缺点,提出了一种将阻抗法与行波法相结合的综合测距方法。结合变电站或电厂内故障录波装置和行波测距装置使用情况,依托主站联网系统,构成了一套完整的故障定位运行分析支撑体系。该系统的建立实现了数据资源共享、故障精确定位,为电力系统故障分析提供了高效的平台支撑。
Impedance method and traveling wave method are common methods for line fault location.Combining the advantages and disadvantages of two ranging methods,this paper proposes a comprehensive ranging method.It combines the use of fault recorder and traveling wave distance measuring device in substation or power plant,and relies on the network system of main station to form a set of complete fault location operation analysis support system.This system realizes data resource sharing and fault location,provides efficient platform support for power system fault analysis.
