摘要
针对接地网腐蚀诊断问题,主要开发了一套变电站接地网缺陷检测系统,简单介绍了接地网仿真软件CDEGS的功能及特点,并利用其中的MALZ模块对变电站接地网进行建模仿真计算.现场实验中通过向接地网注入激励电流源,测量接地网各支路数据,采用ARM9嵌入式系统处理数据,人机交互采用QT软件,将测量结果与CDEGS软件仿真计算的地表磁场分布结果进行对比分析,本系统可以准确检测接地网发生缺陷部位.
To solve the defect diagnosis system for grounding grid, the paper briefly introduces the function and characteristics of the ground simulation software CDEGS, developes a substation defect detection system of grounding grid, and computes the grounding grid model by using the MALZ module. Measuring ground net after the excitation current source injected into the grounding grid in the actual experiment, with ARM9 embedded system processing the data, QT software is used by human-computer interaction, and compared and analyzed with CDEGS software＇ s simulation calculation results that are the distribution of the surface magnetic field. It is easy to diagnose and locate defect in the grounding grid.
