Pumped storage power station arrangement structure
The invention relates to a pumped storage power station arrangement structure, and belongs to the technical field of hydropower engineering. The system comprises an upper reservoir, a lower reservoir and a water delivery and power generation system connecting the upper reservoir and the lower reservoir, and further comprises a first branch and a second branch, the first branch is closer to the upper reservoir than the second branch, the first branch is provided with a first water retaining dam to form the lower reservoir, and the second branch is provided with a second water retaining dam to form a regulating reservoir. The top elevation of the second water retaining dam is higher than that of the first water retaining dam, the adjusting reservoir and the lower reservoir are communicated through a water supplementing tunnel, the upstream end of the water supplementing tunnel is the end connected with the adjusting reservoir, and a gate is arranged in the water supplementing tunnel. On the premise that the reservoir capacity required by engineering power generation is met, on one hand, the shortest water delivery and power generation line can be ensured, the engineering investment is saved, and on the other hand, the important villages can be prevented from being submerged, and the immigrant settlement investment is reduced.
本发明涉及一种抽水蓄能电站布置结构，属于水电工程技术领域。本发明包括上水库、下水库以及连接两者的输水发电系统，还包括第一支流和第二支流，其中第一支流相较于第二支流更为靠近上水库，第一支流设置有第一挡水坝以形成下水库，第二支流设置有第二挡水坝以形成调节水库，第二挡水坝的顶部高程高于第一挡水坝的顶部高程，调节水库和下水库通过补水洞相连通，补水洞的上游端为连接调节水库的这一端，补水洞内设置有闸门。本发明在满足工程发电所需库容的前提条件下，一方面能确保输水发电线路最短，节省工程投资，另一方面还能避免重要村庄被淹没，减少移民安置投资。
