摘要
开发了一套变电站接地网缺陷检测系统,介绍了接地仿真软件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仿真计算。现场通过向接地网注入激励电流源,测量接地网各支路数据,并与CDEGS软件仿真计算的地表磁场分布结果进行对比分析,该系统可以准确检测接地网发生缺陷部位。
The paper briefly introduces the function and characteristics of the ground simulation software CDEGS and developes a sub- station defect detection system grouding 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, it compared and analyzed with CDEGS software＇s simulation calculation results of the distribution in the surface magnetic field, it is easy to diagnose and locate defect in the grounding grid.
