双层接地网对改善接地性能的研究

Research on Double Layer Grounding Grid for Improving Grounding Performance

接地网的合理设计对于改善接地系统的接地性能有着重要意义。由于土地资源日益紧缺,变电站占地面积越来越小,对双层接地网的研究具有十分重要的意义。基于CDEGS仿真软件对双层地网进行仿真分析,完成双层地网在下层地网埋深、面积及网格疏密等参数的布置优化。从而为双层接地网的适用环境以及布置提供理论依据。

The reasonable design of grounding grid is very important for improving the grounding performance of grounding system. Because of the shortage of land resources, the substation area is getting smaller and smaller. Double layer grounding grid is simulated and analyzed based on CDEGS simulation software, complete bi layer grounding network in the lower layer grounding grid buried depth, area and density of the mesh and other parameters of the layout optimization. So it can provide a theoretical basis for the application environment and layout of double layer grounding grid.
