摘要
基于行波法和脉冲信号注入法提出了10kV配电线路单相接地故障的综合定位方法:首先通过行波法来实施定位,检查故障详细的区段以及对应的距离,接着通过脉冲信号注入法对故障位置进行准确的定位。文章在综合定位法的基础上讨论了故障定位装置的软、硬件设计方案,该方法误差小,适用于配网线路单相接地故障的精确定位。
Based on travelling wave method and pulse signal method, a synthetic method of locating the single phase grounding fault in 10 kV distribution line is proposed iri this paper. Firstly, using travelling wave method, the fault zone and corresponding distance can be achieved. Then, by pulse signal injection method, the accurate location can be obtained. On the basis of synthetic locating methods, software and hardware design schemes of the fault locating device are dis- cussed. The proposed method has small error and is suitable for accurate location of single phase grounding in distribution lines.
