抽水蓄能电站既是良好的调峰电源又具有电网调度上的高度灵活性。它与常规水电站相比,除了具有相同的调峰、调相和备用的功能外,还能利用电网低谷时的电力,把电网内成本低的电能,转换为成本高,售价也高的峰荷电能,为整个电网带来经济效益。本文就其功能、作用及效益评价等方面做简要的探究。 Pumped storage power station is not only a good power supply peak regulation but also has a high degree of flexibility in power dispatch. Compared with conventional hydropower stations, it has the same functions of peak shaving, phasing and backup as well as utilizing the electricity at the grid trough to convert the low-cost electric power in the grid into high-cost and high-priced peaks Charge energy, bring economic benefits for the entire power grid. This article on its function, function and benefit evaluation and so on to do a brief exploration.
