Design method for layered water inlet/outlet of hybrid pumped storage power station
The invention provides a method for designing a layered water inlet/outlet of a hybrid pumped storage power station, and relates to the technical field of water conservancy and hydropower engineering.According to the method, excavation and building are conducted on an original ground line, a reserved rock ridge is reserved according to the bottom contour of the original ground line, and the layered water inlet/outlet is formed in the downstream of the reserved rock ridge; the layered water inlet/outlet comprises a set of layered water intake lower layer gates located on the lower portion, and a set of layered water intake upper layer gates are arranged above the layered water intake lower layer gates. Under the water pumping working condition of the hybrid pumped storage power station, water is discharged from the upper-layer gate of the layered water intake, the water pumping lift variable amplitude of the pump turbine is reduced, and then the design and manufacturing difficulty of the pump turbine is reduced; the reserved rock ridge is used for retaining water, and a stilling pool is formed in front of the water inlet/outlet to dissipate energy of drop water.
本发明提供了一种混合式抽水蓄能电站分层进/出水口的设计方法，涉及水利水电工程技术领域，本发明在原地面线处开挖修筑，依靠原地面线底部轮廓保留预留岩坎，预留岩坎的下游设置分层进/出水口，分层进/出水口包括位于下方的一组分层取水口下层闸门，分层取水口下层闸门上方设有一组分层取水口上层闸门。本发明在混合式抽水蓄能电站抽水工况时，从分层取水口的上层闸门出水，降低水泵水轮机抽水扬程变幅，进而减小水泵水轮机的设计及制造难度；且本发明利用预留岩坎进行挡水，在进/出水口前形成消力池对跌水进行消能。
