继电保护计算机整定的断点计算方法的改进

The Improvement of Calculation Method of Break Points in Computer Aided Relay Setting

在总结继电保护机辅整定中断点求法的基础上，针对复杂环网断点的图论求取方法提出了划分区域分别求取和根据线路参数寻求自然解锁点的思想，对两种（Ａ阵法和布尔代数法）典型的断点求取算法进行了一定的优化和改进，并给出算例．

The calculation method of break points in computer aided relay setting in power system is summarized. The area division method is given to calculate the break points and line parameter based natural break points algorithm according to graph theory. The coordination rules of two typical approaches are improved, and the theory and effectiveness in engineering increased.
