水布垭水电站尾水清渣效益分析

Dredging result of tailrace channel of Shuibuya Hydropower Plant

水布垭水电站运行初期,尾水河床形成冲坑和堆渣,抬高了尾水位,对发电有不利影响。清渣以后,发电效益明显增加。

In the early days after the Shuibuya Hydropower Plant was put into operation,the tailrace channel was filled up by a lot of debris and the tailrace water was raised,the energy output consequently reduced.After the debris were cleaned away,the energy output increased obviously.
