摘要/Abstract

摘要： 低压配电网具有线路区段短、分支众多且拓扑结构复杂多变的特点，分布式电源的并网进一步增加了其故障定位的难度。结合图论分析方法和人工智能算法，提出了基于拓扑邻接矩阵的低压配电网故障区段定位方法。首先生成与配电网故障监测单元配置相对应的邻接矩阵，其次建立故障电流在故障监测单元拓扑中的连通性等效模型，根据故障电流从电源到估计故障区段的最短路径计算故障监测信息。以此为基础建立了考虑多重故障的低压配电网故障定位模型并利用粒子群优化算法进行模型求解。仿真算例验证了所提方法能够有效提高故障定位的效率和准确度。

关键词: 低压配电网, 故障区段定位, 邻接矩阵, 最短路径, 粒子群算法

Abstract: The low-voltage distribution network is characterized by short feeder line sections, a large number of line branches, and a complex and changeable topology, and the integration of distributed generation further complicates the faulted line segment location problem. This paper investigates a novel faulted line segment location algorithm by combining the graph theory and artificial intelligence algorithm. Firstly, the adjacency matrix corresponding to the configuration of the fault monitoring units in distribution network is built, then the connectivity equivalent model of fault current in the topology of fault monitoring units is established. The monitoring information of the fault monitoring unit is calculated according to the shortest path from the power source to the estimated fault line section. Based on these works, the fault line segment location model of low-voltage distribution network considering multiple faults is developed, and the particle swarm optimization algorithm is used to solve the model. The results of simulation examples show that the proposed method can effectively improve the efficiency and accuracy of fault location.

Key words: low-voltage distribution network, fault section location, adjacency matrix, the shortest path, particle swarm optimization algorithm
