瑯琊山抽水蓄能电站进水口水力学试验研究

Hydraulic Experimental for the Intake of Langya Mountain Pumped Storage Plant

运用水工模型,对瑯琊山抽水蓄能电站上库进水口进行了水力学试验研究。在抽水和发电两种工况下,研究了进水明渠水面流态、流速场;观测了进水喇叭口附近的漩涡,以考察防涡格栅的效果;仔细研究了进水喇叭口各孔垂线流速分布,并测出进水喇叭口的局部水头损失系数。认为上库进水口的设计是可以接受的。同时,对设计方案的进一步优化提出了建议。

Hydraulic experimental inwestigations of the upper reservoir intake of LangyaMountain Pumped Storage Plant are carried out. The flow patterns and velocity distribulion in theopen channel, the effects of the beams for preventing vertices, and the vertical velocity distributionin the orifices of the intake are studied under two conditions of powergeneration and pumping.And the local head loss coefficient of the intake is also studied. It is considered that the designscheme of the intake is acceptable. At the same time some suggestions are put forward about theforther optimization of the scheme.
