Abstract
In order to solve the problem that the traditional single fault signal is difficult to accurately locate the fault section due to the change of network topology caused by the access of distributed generation to the distribution network,a fault section location method based on multi-objective decision-making is proposed.Based on the characteristics of fault grounding circuit of distributed generator(DG)distribution network,a multi-objective evaluation index system of one-way grounding fault is established,and the fault section is determined by the expected minimum target value to reduce the fault location error.The simulation results show that the multi-objective decision fault section location method can better realize the fault location of distributed distribution network.The distribution network fault location based on the multi-objective decision tree realizes the fusion of multiple indexes,has higher location accuracy,and can accurately locate multiple fault points at the same time especially under the condition of multiple faults in the distribution network.关键词
