配电网故障选线与定位发展现状

Development status of Fault Line selection and location in Distribution Network

本文主要从配电网故障选线与定位发展现状出发。首先分别简单重点介绍了三种接地线路故障的相特征改变分量,利用三种接地线路故障的相特征暂态分量特征,以及利用三种接地线路故障的相特征暂态分量的三种定位选线技术方法,分别为智能识别特征分析法、行波定位测距法和智能化行波测距选线技术。针对各种分析方法的优劣势等并做出了详细分析和总结。

This article mainly starts from the current development status of fault line selection and location in the distribution network.Firstly,it briefly introduces three phase-phase characteristic change components that are the same as the use of three types of grounding line faults,the use of the phase characteristics of the three grounding line faults,the transient component characteristics of the change components,and the phase characteristics that are different from the use of three types of grounding line faults.Three kinds of transient component location and route selection technology methods,and then focus on three kinds of ground fault intelligent identification feature analysis methods,traveling wave positioning and distance measurement method and intelligent traveling wave distance measurement and route selection technology.A detailed analysis and summary are made for the advantages and disadvantages of various analysis methods.
