小电流接地故障仿真分析及选线方法研究

Research on Line Selection Method and Analysis of Small Grounding Fault Simulation

基于小电流接地故障种类繁多、定位困难的现状,提出一种新的单相接地故障定位方法。通过MATLAB仿真分析故障特点,探讨现有选线方法的优劣以及适用范围,通过信息融合技术将多种选线方法结合,用综合选线的方式提高选线精度。

Based on the current situation that there are many types of low-current grounding faults and the location is difficult,a novel single-phase grounding fault location method is proposed.The fault characteristics are analyzed through MATLAB simulation,and the advantages,disadvantages and application scope of the existing line selection methods are analyzed.Through information fusion technology,a variety of line selection methods are combined to improve the accuracy of line selection by means of comprehensive line selection.
