Embodiment Construction
[0029] The present invention provides a pumped-storage power generation system based on water vapor and air pressurization, which includes a high-pressure water storage tank 4, a water turbine generator set 7, a pump 8 and a pool / water tank 17, a motor 1, a compressor 2, a condensate tank 11. Booster pump 12 and secondary auxiliary boost heat source equipment 13. The electric motor 1 and the compressor 2 constitute a compressed air subsystem; the condensate tank 11, the booster pump 12 and the secondary auxiliary boost heat source equipment constitute the steam boost subsystem. An isolation piston 5 is installed in the high-pressure water storage tank 4, and the isolation piston separates the high-pressure water storage tank into two parts, an air space 24 and a water space 25. The electric motor 1 and the compressor 2 are connected by a drive shaft, and the exhaust port of the compressor 2 is connected to the air space 24 of the high-pressure water storage tank 4 through a pip...
