The invention relates to the technical field of pumped storage power stations, and provides a method for increasing the scale of a pumped storage power station to 500 million kilowatts or above. Most of existing pumped storage power stations are about 100 million kilowatts in single body scale, individual pumped storage power stations can reach 200-300 million kilowatts, and the maximum single body installation scale is 360 million kilowatts. The prior art is limited by conditions such as unit technical characteristics, inundation areas of upper and lower reservoirs, investment cost of a water delivery system and an underground powerhouse and the like, and further scale improvement faces many difficulties. According to the invention, the aim of increasing the single body scale of the pumped storage power station to more than 500,000 kilowatts is fulfilled by comprehensively utilizing and using the pelton turbine set, changing the arrangement form of a plant, adopting steel linings for most of water diversion pipelines, utilizing a hoop pipe or winding technology, excavating a water diversion tunnel by utilizing a hard rock heading machine and other technical measures.
本发明涉及抽水蓄能电站技术领域，提供了一种将抽水蓄能电站规模提高到500万千瓦以上的方法。现有抽水蓄能电站单体规模多数在100万千瓦左右，个别可到200‑300万千瓦，最大的单体装机规模为360万千瓦。现有技术受机组技术特征、上下水库淹没面积、输水系统及地下厂房投资成本等条件限制，规模进一步提升面临诸多困难。本发明综合利用，使用水斗式水轮机组、改变厂房布置形式、引水管道大部分采用钢衬、利用箍管或缠绕技术、利用硬岩掘进机开挖引水隧洞等技术措施，以实现将抽水蓄能电站单体规模提高到500万千瓦以上的目的。
