美国和西欧、亚洲、非洲的一些工业发达国家,在最近10～15年时间里,都有一些大型的地下式地面式抽水蓄能电站已经投产或者正在加紧兴建,其装机容量大都是100～200万千瓦,水头是200～500米。在现代国外电力系统里,这些电站是削峰的最佳电源,是填谷的有效措施,起着平衡日周调节 In some industrialized countries in the United States, Western Europe, Asia and Africa, some large underground groundwater pumped storage power stations have been put into operation or are under construction in the recent 10 to 15 years. The installed capacity is mostly 100-200 Million kilowatts, the head is 200 ~ 500 meters. In the modern foreign power system, these power plants are the best power source for peak shaving, an effective measure for filling the valley, and they play a role of balancing day-week regulation
