摘　　要：针对现有配电网故障区域定位算法存在的问题,提出一种基于故障过流度的配电网故障区域定位新矩阵算法。该算法通过网络描述矩阵和故障信息矩阵计算比较故障时各区段的故障过流度,判定发生故障的区段,实现对配电网的故障定位。算例分析表明,该算法有效,适用于单电源、多电源和馈线末端故障等各种情况。This paper analyzes the problems of existing fault location algorithm for distribution network, and proposes a new matrix algorithm based on fault over-current level. The proposed algorithm calculates and compares fault over-cur- rent levels of each section through the network description matrix and fault information matrix, determines the fault sec- tion and realizes the fault location. The algorithm is suitable for both single-supply and multi-supply distribution network, and faults occurring at the feeder end can also be located. The example proves the effectiveness of the proposed algorithm.
