摘要
提出了一种基于相模变换和频谱分析的电网行波故障定位算法,该方法将故障定位装置布点问题,利用相模变换转化为整数规划问题予以求解。仿真结果表明该算法不受故障电阻、故障初始角以及负荷变化因素影响,整体费用小、可靠性、准确性较高的优点。
Reliable and accurate fault location for distribution network is the basis and prerequisite for fault isolation and removal,and power restoration. This paper proposes the grid traveling wave fault location algorithm based on the phase mode transformation and spectral analysis. This method uses phase mode transformation and derives solution to integer programming problem. The simulation results show that the algorithm is not affected by fault resistance,fault initial angle and load change,with the advantages of small overall cost,high reliability and accuracy.
