摘　　要：混合式抽水蓄能电站是一种既有抽水蓄能又有径流发电功能的水电站,是一种优质的长时蓄能方式,有助于推动流域水风光蓄一体化清洁能源基地开发。从规划选址、工程设计、施工建设、调度运行等方面,对混合式抽水蓄能电站的建设运行的关键工程技术问题进行了研究。研究认为:混合式抽水蓄能电站不需要新建上、下水库,建设征地移民少,可与原常规水电站一并打捆送出,但需要重点考虑对生态环境和原水库的影响,从而合理论证装机规模。特别要在机组设计制造、长距离引水发电系统设计、已建水库进/出水口施工、抽水可靠度与河道疏浚、一体化运行调度方式等诸多方面深入研究论证,优化工程投资。建议择优选址,因地制宜、稳步推进开发混合式抽水蓄能电站。Hybrid pumped storage power station is a hydroelectric power station that has both pumped storage and runoff power generation functions.It is a high-quality long-term energy storage way that helps promote the development of integrated clean energy bases composed of water,wind,and solar energy in a basin.This article explores the key issues in the construction and operation of hybrid pumped storage power stations from the aspects of site selection,engineering design,construction,and operation scheduling.The hybrid pumped storage power station does not require constructing new upper and lower water reservoirs,and requires few land acquisition and none immigrations.Electricity produced by the hybrid pumped storage power station can be bundled and sent out together with the traditional hydropower station.But it is necessary to focus on the impacts on the ecological environment and the supported reservoirs,so as to reasonably recommend the installed capacity by technical and economic comparison.To optimize engineering investment,many researches are need in unit design and manufacturing,long-distance water diversion and underground powerhouse system design,construction of inlet and outlet at the existing reservoirs,the analysis of pumping reliability and river dredging,and integrated operation and scheduling scheme,etc.This article suggests optimizing site selection according to local conditions,and steadily promoting the development of hybrid pumped storage power stations.
