摘　　要：为探讨400 kV开关站地网接地电阻和安全性能参数是否符合设计要求,使用CDEGS软件和IEEE Std 80-2013进行计算,分析比较2种方法在土壤电阻率的数据整理分析、地电位升、接触电压、跨步电压等多方面的差异。结果表明,采用CDEGS软件和IEEE Std 80-2013两种分析结果基本一致。In order to investigate whether the grounding resistance and safety performance parameters of the ground gridof the 400 kV switch station meet the design requirements, the CDEGS software and IEEE Std 80-2013 are used tocalculate them; and then analyze and compare their differences in many aspects such as data sorting and analysis of soilresistivity, ground potential rise, contact voltage and step voltage etc. The results show that these two kinds of analysisresults of CDEGS software and IEEE Std 80-2013 are coincident basically.
