摘要

对地网进行故障诊断的时候

经常遇到拓扑结构与地网设计图纸不符的情况

这种情况对腐蚀诊断的结果具有一定影响。本文基于特勒根定理和最优化方法

结合实际变电站地网

利用ATP和MATLAB进行了仿真实验。通过实验得出的数据对该影响进行分析

得到了一种有效的修正方法

该修正方法有效地降低了拓扑改变造成的影响

提高了诊断精度

具有工程实用性。

Abstract

When diagnosing the eroded grounding grids

it finds that the topology of the grounding grids is usually different from the drawing paper

which has an influence on the diagnosis.On the basis of Tellegen theorem and Optimal Method

the author does a modelling exercise which is combined with the actual grids in substation with the use of ATP and MATLAB.In this study

the author uses the experimental data to analyse the influence and gets an effective correct method.This method effectively reduces the influence caused by the change of topology and improves the diagnosis.It proves engineering practicability.
