Compressed air electric power energy storage system

The utility model discloses a compressed air electric power energy storage system, including constant voltage gas storage device, high -pressure stock solution device, energy storage component and energy release subassembly. Under the energy storage state, the energy storage component turns into air internal energy with the electric energy and saves in proper order in constant voltage gas storageunit, adjusts constant voltage gas storage device's the invariable and recycling liquid of pressure through hydraulic pump and hydraulic motor generating set, under the energy release state, high -pressure gas among the constant voltage gas storage unit passes through the expander assembly acting and drives the generator electricity generation, simultaneously high -pressure stock solution device in to constant voltage gas storage unit the injected liquid body to maintain its pressure invariable to utilize the hydraulic pump aggregate to retrieve the liquid among the gas storage unit who accomplishes energy release.
