摘　　要：向家坝—上海±800kV特高压直流复龙换流站接地极按三站共用接地极设计,共用接地极相比常规独立接地极有其设计特点和技术难点。在共用接地极设计系统运行条件的选取、共用接地极布置方案、导流系统设计、馈电材料选择、大电流接地极对电力系统的影响等方面,其设计研究成果可为后续工程提供借鉴。Fulong converter station of Xiangjiaba-Shanghai ±800 kV UHV DC line has a common ground electrode shared by 3 stations, which has its own design and technical challenges compared to regular independent ground electrodes. The results of design study in such aspects as operating condition selection and arrangement of common ground electrode, diversion system design, feed material selection, effect of large ground electrode current on power system, etc., can be used as references for following-up projects.
