智慧能源站的接地系统优化设计

Optimum Design of Grounding Systemfor Intelligent Energy Station

当智慧能源站中发生大电流接地故障时,为维护设备可靠运行、保障运行人员和设备安全,需设置接地系统。首先确定智慧能源站的接地型式;然后在分析变电站、数据中心站、储能站、光伏接地要求的基础上,明确智慧能源站的接地要求;在采用普通复合接地网无法满足要求的前提下,提出采用复合立体主接地网对智慧能源站接地进行优化设计,并利用CDEGS软件仿真验证。

When a large current grounding fault occurs in a intelligent energy station,the grounding system should be set up to maintain the reliable operation of equipment and ensure the safety of operators and equipment.Firstly,the grounding type of intelligent energy station is determined.Then,on the basis of analyzing the grounding requirements of substations,data center stations,energy storage stations and photovoltaic power stations,the grounding requirements of intelligent energy stations are defined.On the premise that the common composite grounding grid can not meet the requirements,the composite three-dimensional main grounding grid is proposed to optimize the grounding design of intelligent energy station,and the simulation results are verified by CDEGS software.
