建设抽水蓄能电站必要性的思考

抽水蓄能电站具有填谷调峰的优良特性。详述了调频、调相、负荷调整、旋转备用、提高电网可靠性的辅助功能以及世界和中国抽水蓄能电站的发展情况。提出我国在火电比重大和建设核电站的电网及"西电动送"受端电网,优先发展抽水蓄能电站,在水电比重较大,但调节性能差的电网,适当配置抽水蓄能电站。抽水蓄能电站一般应修建在负荷中心附近,且有天然湖泊或已建水库处。

The Importance of Constructing Pumped-storage Power plants in China

Pumped-storage power plants can undertake the tasks of filling valley and modulating peak. In this paper, its subsidiary functions to modulate the frequency, phase and load, to reserve energy, and to enhance the reliability of power grid are introduced in detail. Besides, the development of pumped-storage plants in China and over the world is also presented. It is put forward that the priority of development should be given to pumped-storage plants in those power grids where thermal power generation occupies a large proportion, or there are nuclear power plant constructions, or it is an acceptor of the operation mode of transmitting power from West China to East China, and that pumped-storage plants should be collocated appropriately where hydroelectricity occupies a rather large proportion, but of poor modulation property. Generally speaking, pumped-storage plants should be constructed near the load and natural lakes or already-constructed reservoirs.
