一种基于图论剪枝算法的多分支配电网行波故障定位算法
A traveling wave fault location method for distribution network based on pruning algorithm and graph theory
摘要
Abstract
The structure of distribution network likes multi-branch radial tree , which causes difficulties in fault loca-tion.There will be much error if the traditional fault location method IS used directly .Therefore, a novel traveling wave fault location method for distribution network based on graph theory and pruning algorithm is proposed in this pa -per .In this method , the initial traveling wave information is used to determine the arriving time of wave front .And distribution network topology model is equivalent to graph theory model which is built by distance matrix and correla -tion matrix.The pruning algorithm is used to cut invalid information .Accurate fault location of distribution network can be realized through the whole process .Finally , PSCAD and MATLAB software are used to test the location meth-od.And simulation results show that the method has improved the accuracy and reliability of distribution network fault location .关键词
