配电网故障定位的一种改进通用矩阵算法
An improved general matrix algorithm for fault locating in distribution system
摘要
Abstract
An improved general matrix algorithm is presented to locate faults in complex distribution networks with multiple source and multiple faults. Firstly, the paper supposes the only power source and the positive direction according to the system's structural characteristics, and establishes the description matrix D which is based on the positive direction and the relevancy between different feeders. Secondly, we install three working modes in the feeder terminal units (FTU), including positive over-current, reverse over-flow and normal model, transform the diagonal elements of the matrix D based on the direction sent from the feeder terminal units(FTU) to set up the fault judgment matrix P. Finally, we locate the fault section using the criterion. This method needs not matrix multiply or standardization. It's easy to build the description matrix D, which is very sparse and has small amount of calculation and speedy judgment.关键词
