摘　　要：终端变电站的建设对于优化电网结构具有重要的意义。分析了500 kV终端变电站站址选择的一般性原则,给出了500 kV终端变电站方案可行性论证思路,结合广东电网"十二五"规划网架,讨论了500 kV终端变电站在广东电网中的应用方案。对所提方案进行电气计算、可靠性和经济性分析比较,得出广东电网终端变电站建设推荐方案。The construction of terminal substations is very important for grid optimization. First, the general principles of site selection for the 500 kV terminal substation are analyzed. Then methods for demonstrating the feasibility of 500 kV terminal substation construction schemes are proposed. Finally, the application schemes of the 500 kV terminal substation in Guangdong Power Grid of the Twelfth Five-Year Plan are discussed. These schemes are compared in electrical calculation, reliability evaluation and economic analysis, and the recommended scheme is given for Guangdong Power Grid.
