摘　　要：长期以来,接地网腐蚀诊断一般通过大面积开挖的方法,此方法盲目性、工作量极大,且影响电力系统正常运行.以往提出的一些故障诊断方法对较小型地网有一定效果,但是对中大型地网的实用价值极小.通过大量仿真计算对中大型接地网腐蚀优化诊断进行了研究,提出在接地网腐蚀诊断时采用分步分块优化测量的方法.该方法可以实现不停电、不大面积开挖接地网的条件下,快速准确诊断大型接地网腐蚀情况.现场实用表明该优化诊断方法效果良好,基本达到工程要求.To find the corrosion of the grid ,large area cutting has been adopting in practice for a very long time. But this method is blind, difficult and influences the system operating. The erosion diagnosis method in the past is effective for the smaller grid. To the brand ones, it can not take effect. The method of separating the grounding grid into several parts and diagnosing step by step is discussed by lots of simulation about middle or brand grounding grid erosion diagnosis. This method makes the brand grounding grid erosion diagnosis quick and truly without power cut and digging large area, satisfies the demand in practice. Putting this optimized diagnosis method into practice , the result is good.
