摘　　要：对发、变电站接地网腐蚀及断点的诊断方法进行研究。将接地网等效成纯电阻网络,运用电网络理论、模拟电路故障诊断理论以及最优化技术,建立接地网的故障诊断方程组。用Matlab数学工具求解方程组,分析接地网运行前后的情况变化,判断出接地网腐蚀和断点的情况。This paper discuses the method with which the corrosion of the grounding grid can be diagnosed .A grounding grid can handled as a circuit network. With the application of circuit network graph theory and the fault diagnosis theory of analog circuit and optimization, the fault diagnosis equations can be set up. This equations is figured out by Matlab, and the corrosion status of the grounding grid can be deduced from the result.

关 键 词：接地网 故障诊断 腐蚀
