法国大屋抽水蓄能电站,通过一条引水遂洞在同一地点不同高程处设置地面和地下两个厂房,分别安装常规冲击式机组和可逆式机组,总装机容量达1800MW,两个厂房由3条高压管道分别与各机组相连,形成复杂而紧凑的地下洞群。其可逆式机组不带可调导水叶,而由球阀调节水量启动发电机,省去调速器。在抽水工况下,常规冲击式机组兼作可逆式机组的启动马达 France Danyu Pumped Storage Power Station, through a water diversion tunnel at the same location at different elevation set up two ground and underground plants, respectively, the installation of conventional impact units and reversible units, with a total installed capacity of 1800MW, two plants by the three high-pressure The pipes are respectively connected with each unit to form a complex and compact underground caverns. The reversible unit without adjustable guide vane, but by the ball valve to adjust the amount of water to start the generator, eliminating the governor. In pumping conditions, the conventional impact unit also serves as the start-up unit for the reversing unit
