The invention provides a pumped storage power station which comprises an upper reservoir, a lower reservoir and a transition reservoir, the upper reservoir, the lower reservoir and the transition reservoir are sequentially connected through water conduits, the transition reservoir comprises a reversible water turbine and a water storage pond, and the water conduits are further connected between the reversible water turbine and the water storage pond. By the adoption of the technical scheme, the transition reservoirs are arranged between the upper reservoir and the lower reservoir, the transition reservoirs have the grading effect on the water head difference between the upper reservoir and the lower reservoir, and therefore the water flow pressure acting on the water turbines in the single transition reservoir is greatly reduced, and the probability that water hammers are formed in water flow is reduced; in addition, in the single transition reservoir, tail water flowing through the water turbine is fed into
