三板溪水电站尾水河床疏挖效益研究

Tailwater river of SANBANXI Hydro-Power dredging effectiveness studies

通过对三板溪水电站尾水河道疏挖水力学计算和水下开挖方案的研究,尾水疏挖是充分开发利用河段水力资源和水电站增加发电量的有效途径。经计算分析比较推荐水电站尾水疏挖方案为方案3。尾水疏挖后,电站可增加发电量,经济效益十分显著。

By studying hydraulics and underwater excavation scheme on Sanbanxi tailwater river dredging, water station proposed dredging tail recommended solutions. After the tail water dredging, power consumption can be additional economic benefits is very significant. Tailrace dredging is fully exploited river water resources, hydropower additional effective way to power, and in engineering practice should be widely applied.
