基于规范算法的电力系统复杂故障计算的实用性改进
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.
