摘要

为了避免在故障计算中重复计算全网阻抗矩阵元素

介绍了一种规范的计算机算法

对算法的核心部分

即故障描述矩阵Yf进行了分析。首先论述了数学上Yf的列写过程

然后根据推导的2类典型故障

总结得到电网理论上出现N处错误时Yf的实用化公式并给出了电路上的解释

并在工程项目中得到了应用。

Abstract

In order to avoid calculating the impedance matrix elements of the whole network repeatedly

a canonical computer algorithm suiting for various complicated fault is introduced in this paper.The form of the matrix in mathematics

a core part in the algorithm

is analyzed.A general format of the by deducing two types of typical fault is presented and the explanation in real fault circuits is given.
