抽水蓄能进行发电的水电工程已在电力系统中成为一种新的调节型式被广泛采用。这种开发型式虽然不能产生新的电能,但它具有“调峰填谷”的特有作用。利用这一特点.抽水蓄能电站在电力系统中发挥着越来越重要的作用。抽水蓄能发电站的建立不仪对电网系统有一定的作用(例如电网系统利用抽水蓄能发电进行调峰的需要和可能等条件),同时还必须具备一定的地形、地质和水文条件:在下库附近具有修筑上库的地形条件,并在较短距离内具有较大的地形高差;下库 Hydropower projects that generate electricity for pumped storage have become widely accepted as a new type of regulation in power systems. Although this type of development can not generate new electricity, it has the peculiar function of “peak filling”. Taking advantage of this feature, pumped storage power plants play an increasingly important role in the power system. The establishment of pumped-storage power stations not only has some effect on the power grid system (for example, the grid system needs the possibility of peak regulation using pumped storage power generation and other conditions), but must also have certain topographic, geological and hydrological conditions: There is topographical conditions for building the upper reservoir near the reservoir and a greater elevation difference in a shorter distance. The lower reservoir
