Mixed medium type pumped storage method and energy storage device
According to the mixed medium type pumped storage method and the energy storage device, when a pumped storage power station discharges water to generate power, the energy storage device is used for putting a solid admixture into a water inlet tunnel to form a mixed medium, a water turbine is pushed by the mixed medium to generate power, and solid-liquid separation and recovery are conducted on the mixed medium discharged by the water turbine; the separated solid admixture is conveyed to the position above a water inlet tunnel, separated water is discharged into a lower reservoir, the circulating energy storage power generation process of mixed media is achieved through circulating putting and recycling, and a larger energy storage scale is achieved under the condition that the height difference of the pumped storage power station is kept unchanged. And under the condition of keeping the energy storage scale of the pumped storage power station unchanged, the site selection limitation is reduced, and the construction site selection flexibility of the pumped storage power station is improved.
本发明提出一种混合介质式抽水蓄能方法及储能装置，在抽水蓄能电站放水发电时利用储能装置将固体掺料投放至进水隧洞形成混合介质，由混合介质推动水轮机发电，并将水轮机排出的混合介质中进行固液分离回收，将分离后的固体掺料输送至进水隧洞上方，分离后的水排放到下水库中，通过循环投放回收实现混合介质的循环蓄能发电过程，在抽水蓄能电站高差保持不变的情况下实现更大的储能规模，并在保持抽水蓄能电站储能规模不变的情况下降低了选址限制，提高了抽水蓄能电站建设选址的灵活性。
