摘　　要：抽水蓄能电站占地面积大,二次系统分布地域广,在进行等电位接地网设计和敷设过程中容易出现问题。本文以仙游抽水蓄能电站具体的二次等电位接地网为例,指出了二次系统等电位接地网目前存在的缺陷,提出了各个分布式区域二次等电位接地网的设计方案和连接方式,并通过现场勘查和理论分析,在二次设备一点入地的原则上确定了分布式等电位接地网接入主地网的位置。The pumped storage power station has a large area and its equipotential grounding grid system has a wide geographical distribution.It is prone to problems in the design and connection process of the equipotential grounding grid.Taking the equipotential grounding grid of Xianyou Pumped Storage Power Station as an example,its shortcomings are pointed out.The design scheme of equipotential grounding grid in each distributed area is designed. The location of the equipotential grounding grid connected to the main ground grids determined by survey and theoretical analysis and the aim of single point grounding is realized.
