摘要
国家电网公司1000kV晋东南—南阳—荆门特高压交流试验示范工程已经成功投运。其中1000kV GIS(HGIS)的接地设计,因其电压高、容量大而具有新的特点,结合施工条件提出了设置辅助地网的概念,同时分析论述了1000kV GIS(HGIS)感应电流情况和辅助地网的主要技术原则。
1000 kV Jindongnan-Nanyang-jingmen UHV AC pilot demonstration project of SGCC has been successfully put into operation.During construction 1 000 kV GIS（HGIS）grounding design has new characters due to its high voltage and large capacity. The paper puts forward the conception of setting auxiliary grounding grid in combination with construction conditions,analyzes and demonstrates the main technical principles for 1 000 kV GIS （HGIS）induced current and auxiliary grounding grid.
