新疆奎屯河新龙口水电站水系统供水方式优化设计

Optimal Design of Water Supply Mode of Xinlongkou Hydropower Station on Kuitun River in Xinjiang

针对奎屯河引水工程新龙口水电站引水系统压力管道水压高、夏季水中含泥沙量相对较大的特点,设计采用顶盖排水供机组技术冷却水的方式,相比采用常规的自流减压、闭式循环供水方式,水电站的运行更加节能、经济、高效,有非常可观的经济效益。

In view of the characteristics of xinlongkou hydropower station of Kuitun River Diversion Project,such as high water pressure in the penstock of diversion system and relatively large sediment content in summer,with the progress of industrial technology,the design method of using top cover drainage to supply technical cooling water for units has become more and more mature.Compared with the conventional gravity decompression and closed circulating water supply method,the operation of hydropower station is more energy-saving and economical It is economical,efficient and has considerable economic benefits.
