配电网故障区间判断的改进型矩阵算法（Improved Matrix Algorithm for Fault Section Detection in Distribution System）
配电网络 馈线自动化 故障定位 故障小区 故障判断矩阵
2010/8/17
在馈线终端单元（FTU）装置中设置三种工作模式，在此基础上提出一种分区判断故障的改进型矩阵算法。首先采用分区的思想以常开型联络开关为界将配电网络分成许多小区，根据故障信息粗略判断出发生故障的小区。针对发生故障的小区形成网络描述矩阵，根据不同工作模式下的故障信息对网络描述矩阵进行修正形成故障判断矩阵，根据故障判断矩阵中的元素特征就可判断故障发生区间。仿真结果表明此算法判断正确，没有产生漏判现象。
