摘　　要：随着西电东送规模的扩大, 广东地区将建设越来越多的换流站, 而接地极的选择则是个难题。通过分析广东电网的情况及广东地区经济发展状况, 提出新建的换流站在现有基础上共用接地极的设想, 并对共用接地极的技术问题进行了初步的分析和讨论。With the expansion of the scope of power transmission from west China to east China,more and more converter stations will be constructed in Guangdong and the siting of their earth electrodes will be a difficult problem.By analyzing the situation of power grid and the economic growth in Guangdong, a tentative plan is proposed that future converter stations should share the existing earth electrodes.A preliminary analysis is also made of the technical points in sharing the earth electrodes.
