中偏尾部开发方式在洛宁抽水蓄能电站中的应用

Layout Scheme of Powerhouse at the Middle and Lower Section of Power Tunnel for Luoning Pumped-storage Power Station

洛宁抽水蓄能电站最大水头652 m,输水线路水平长度大于4.2 km,是典型的高水头、长输水道抽水蓄能电站。与传统的中部式和尾部式方案相比,中偏尾部厂房布置方案可有效降低工程造价,且能够保证调保参数和运行管理均较优。过渡过程计算结果也表明,中偏尾部厂房布置方式是可行的,且结构尺寸仍有优化可能。

Luoning Pumped-storage Power Station is one high-head and long-tunnel pumped storage station, in which, the maximum head is 652 m and the horizontal length of water delivery tunnel is more than 4.2 km. Comparing to traditional powerhouse layout schemes at the middle or the tail position, the layout of powerhouse at the middle and lower section of power tunnel can effectively reduce project costs, and guarantee more optimal regulating guarantee capacity and better operation management. The computation of transition process proves that this layout of powerhouse is feasible and the size of powerhouse may still be optimized.
