摘要

已有的大规模接地网故障诊断算法的计算量非常大

导致计算时间很长

在实际应用中很不方便。为了解决该问题

笔者在已有的故障诊断方法基础上

提出了一种利用计算机局域网络的分布式算法。由主模块控制并发送所需计算的样本到分散在各台计算机上的各个从模块

各个从模块进行并行运算

并反馈运算结果至主模块。主模块在将所需要的结果全部收集完整后进行分析处理得到最终的结果。详细论述了接地网可测性分析、不确定支路取值范围估计以及新建接地网监测极优化布置这三个算法的分布式处理过程。以一个具体的60条支路的实验接地网为例

基于一个具有5台计算机的局域网

采用提出的方法进行了分析

并与已有方法进行了比较

结果表明所提出的分布处理方法是可行的

并且能大幅提高处理速度。

Abstract

With large amount of calculation

the existing grounding grid corrosion diagnosis algorithms need rather long time and are inconvenient in the practice.To solve above problem

a local area network （LAN） based approach was put forward

which convert the traditional algorithms into some distributed processes.The master module controls the whole process and sends the samples needed to be calculated to the slave-modules distributed on the computers of the LAN.The slave modules calculate the samples simultaneously and transfer the results back to the master module.All the results being collected

the final result will be worked out by the master module.The distributed approaches of grounding grids testability analysis

uncertain branches evaluation and monitoring line positions optimization were discussed in detail.An experimental grounding grid with sixty branches was used as an example to test the proposed distributed approaches.The test is based on a LAN with five computers and compared with the existing methods

the results of which show that the proposed methods are feasible and can remarkably reduce the calculating time.
