摘　　要：目前降低变电站接地电阻主要采用的降阻措施常用的方法有增大接地网的面积、引外接地、增设垂直接地极、换土等。本文结合贵州地区实际变电站工程,介绍了以深井离子接地极为主的复合接地网在变电站接地中的应用及相关的参数计算。并对接地网设计中的注意事项作出小结。The primary measures to reduce substation grounding resistance were as follows： expanding grounding net area, leading to external, adding the vertical grounding electrodes, exchanging the soil etc. Combining actual substation project in Guizhou area, this paper introduced deep well ion grounding composite ground net and its application and related parameters calculation in substation grounding. Lastly, the matters needing attention in the design of grounding systems were summarized.
