摘　　要：刘巴足35 kV变电站的接地网系统由于运行年长,接地网腐蚀情况严重,接地电阻值偏大,因此需要对接地网进行改造,改造施工前对35 kV变电站的土壤环境、接地电阻和接地网热稳定性进行了分析计算,最后运用电磁暂态仿真软件PSCAD构建了35 kV变电站的接地电阻仿真模型,模拟了变电站使用不同接地材料下接地电阻情况,通过分析计算35 kV变电站接地网各项数据和模拟接地网运行情况,有效保障了变电站接地网改造工程实施的可靠性,对变电站接地网合理布置和改造更换具有指导作用。Due to the years operation,the grounding system in Liubazu 35 kV substation network has being corroded seriously,the Resistance became larger than permission,so the transformation work is critically needed for grounding network. Before the engineering,surrounding soil environment,grounding Resistance ratio and grounding heat stability are studied. The next step is to set up the simulation model with software of PSCAD,which simulates the grounding Resistance of the substation under different grounding materials. By analyzing and calculating the data,the transformation scheme is verified,which guarantee the reliability,and provide guidance in grounding grid transformation.
