| 摘 要： | 福建省闽江上游支流的河床式水电站有水头低、流量大、河道地形多变的特点,灯泡贯流式发电机组出力对上、下游水头差极为敏感。通过对金溏水电站尾水出口段河床滩地清理水力计算,在获得满足不影响电站机组出力要求的尾水段开挖高程和型式布置,使滩地开挖量较小。

| Abstract: | The river bed type hydropower plants located on the upstream tributaries of the Minjiang River are characterized by low head,large discharge and variable topography of river channels,and the output of a bulb through flow type turbo-generator unit is extremely sensitive to upstream and downstream head difference in Fujian Province.The hydraulic calculation for cleaning of alluvial plain in the tailrace outlet section of Jintang Hydropower Project was made to reduce excavation quantity of the alluvium plain o... |
