摘要

随着分布式电源接入配电网，电流变为双向流动，导致传统的故障区段定位方法不再适用。为解决含分布式电源的配电网故障区段定位问题，提出了一种基于可达矩阵和贝叶斯定理的故障区段定位方法。不同于传统矩阵算法中使用邻接矩阵描述网络拓扑的思路，使用蕴含信息量更大、全局可观性更强的可达矩阵进行拓扑描述和矩阵运算。为应对信息畸变，利用贝叶斯定理进行容错处理，从而找出故障区段。算例结果表明：该方法具有良好的通用性，对于电机型和逆变型分布式电源，可以统一处理。对于含分布式电源的配电网中的单个故障和多重故障，该方法能够准确定位故障区段并且具有一定的容错性。

Abstract

With the distributed generation connected to the power distribution network

the current becomes a bidirectional flow

which results in the traditional fault location method no longer applicable. In order to solve the problem of fault section location in power distribution network with distributed generation

a fault location method based on reachability matrix and Bayes' theorem is put forward. Different from the idea of using adjacency matrix to describe the network topology in traditional matrix algorithm

the reachable matrix which contained more information and had stronger global observability is used for topology description and matrix operation in this paper. To deal with information distortion

the Bayes' theorem is utilized in fault tolerance processing to find out the fault section(s). Simulation results of test cases show that the proposed method has good generality as it can handle both generator-based and inverter-based distributed generation in a uniform way. For single fault and multiple faults in the distribution network with distributed generation

the proposed method can locate fault section(s) accurately and has certain fault tolerance.
