Flood drainage system and method for pumped storage power station
The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a flood drainage system and method for a pumped storage power station. The flood drainage system of the pumped storage power station comprises a flood drainage tunnel, an energy dissipation building, a stilling pool and a protection facility, the flood drainage tunnel comprises a gentle slope base layer and an abrupt slope base layer, the abrupt slope base layer is provided with an energy dissipation section in a calibration range of an outlet of the flood drainage tunnel, the energy dissipation section comprises a diffusion area and a broadening area, and the energy dissipation building comprises multiple energy dissipation steps. The multi-stage energy dissipation steps in the diffusion area are used for gradually changing the water flow velocity, the stilling pool is connected to an outlet of the flood drainage tunnel, and the protection facility is connected between an outlet of the stilling pool and an original riverbed covering layer. The upstream water flow passes through the multi-stage energy dissipation steps and the stilling pool to dissipate the energy of the water flow, and the energy-dissipated water flow is transited to the original riverbed covering layer through the protection facility, so that the influence on the downstream environment is reduced, and the original riverbed covering layer is protected.
本发明涉及水利与水电工程技术领域，具体涉及一种抽水蓄能电站排洪系统及排洪方法。抽水蓄能电站排洪系统包括排洪隧洞、消能建筑物、消力池以及防护设施，排洪隧洞包括缓坡基层和陡坡基层，陡坡基层位于排洪隧洞出口的标定范围内布置有消能段，消能段包括扩散区域和扩宽区域，消能建筑物包括多级消能台阶，扩散区域内的多级消能台阶用于渐变水流流速，消力池衔接在排洪隧洞的出口处，防护设施衔接在消力池出口和原河床覆盖层之间。本发明利用使上游水流通过多级消能台阶和消力池，进行水流能量的消能，以及消能后的水流经过防护设施过渡至原河床覆盖层，减少对下游环境的影响，保护原河床覆盖层。
