基于故障方向测度的配电网故障区段定位方法
A Method of Fault Section Location in Distribution Networks Based on Fault Direction Measures
摘要
Abstract
A method of fault section location in distribution networks based on fault direction measures was proposed to solve the problem of the single phase-to-earth fault location in distribution networks.Referencing the load current,the fault direction measures of the fundamental zero-sequence current was established.Applying the phase space reconstruction,the fault direction measures of the transient phase current peak value were constructed to indicate the fault direction of a single measuring point and quantitatively to evaluate the significance level of the fault features.Based on 0-1 integer programming,the multi-criteria decision-making and the optimization model of the fault direction measures were developed.The multi-target decision-making problem was transformed into a single-criteria optimization by introducing the credibility evaluation theory.Then the fault locating depending on multiple measuring points was achieved.The simulation and experiment results demonstrate the high fault locating accuracy.The method needs less information,and can accurately locate the fault section in the case of distorted information,and has excellent fault-tolerant performances.关键词
