摘　　要：变电站接地网可以为故障电流或短路电流提供流散的通路,以此来保障变电站中的设备正常运行及工作人员的安全。通过计算变电站工频接地电阻来衡量接地网的散流性能,本文利用电力系统分析软件CDEGS来对变电站接地网的工频接地电阻进行仿真与计算,并且就接地网的拓扑结构以及接地网所处土壤的特性等因素对变电站接地网工频接地电阻的影响展开分析与研究,旨在为变电站接地网工频性能的优化提供理论依据。The grounding grid of substation can provide a dissipation path for fault current or short-circuit current,so as to ensure the normal operation of equipment in substation and the safety of staff.In this paper,the stray current performance of the grounding grid is measured by calculating the power frequency grounding resistance of the substation,the power frequency ground resistance of the substation grounding grid is simulated and calculated by using the power system analysis software CDECS,the influence of the topological structure of the grounding grid and the characteristics of the soil where the grounding grid is located on the power frequency ground resistance of the substation grounding grid is analyzed and studied,aiming to provide a theoretical basis for the optimization of the power frequency performance of the substation grounding grid.
