论述了２０１０年三峡电站投产可承担系统的部分调峰任务，使火电机组的调峰性能提高，但在系统调峰容量明显扩大的情况下，华中电网建设抽水蓄能电站是必要的． This paper discusses some peaking tasks of the Three Gorges hydropower station that can bear the system in 2010, which can improve the peaking performance of thermal power units. However, when the capacity of peaking peak capacity is obviously enlarged, it is necessary to build pumped storage power station in Huazhong Power Grid.
