摘　　要：本文针对三峡水电站的建设，结合华中电网的中长期规划，计算分析了未来华中电网的短路电流水平及其变化趋势，并参照国外大电网建设和运行经验，提出了限制２２０～５００ｋＶ电网短路电流的措施和方法，研究了三峡水电站分厂方式和接入系统方案对电网短路电流的影响，并提出了解决办法。According to medium and long term planning of Central China Grid(CCG)and construction program of ThreeGorges Hydroproject,in this paper analysed the future short circuit current(SCC)level and its developing tenden-cy of Central China Electric Network is analyzed.Taking foreign big grids construction and operation experience asreference,the authors put forward tneasures and rnethods of restriction on SCC in 220～500kV grids,made re-searches on connection of Three Gorges Hydroprojct to the CCG nad SCC's influence upon the CCG,and introducedthe ways of solving the problems mentioned in the paper.
