The invention discloses a compressed-air energy-storing
power generation system adopting an unsteady state compression process. The compressed-air energy-storing
power generation system adopting the unsteady state compression process comprises a compressor unit, an air storage device, a
turbine generator unit and a heat
recovery system, wherein an outlet of the compressor unit is connected with an inlet of the air storage device, and the compressor unit provides
compressed air for the air storage device. When the compressor unit provides the
compressed air for the air storage device, the pressure of the outlet of the compressor unit synchronously changes along with the pressure in the air storage device, the air storage device stores the
compressed air of the compressor unit and provides the compressed air for the
turbine generator unit, the heat
recovery system feeds back compressed heat to air of the
turbine side to improve the temperature of the air, and therefore work of the air can be improved. According to the compressed-air energy-storing
power generation system adopting the unsteady state compression process, by means of achievement of synchronous change between the
discharge pressure of the outlet of the compressor unit and the air-storing pressure,
gradual increase of the power of the compressor unit can be achieved. Due to the unsteady state compression process, under the condition that the compressed air in the same situation is obtained,
electric energy consumed by the compressor unit can be reduced, and the transferring efficiency of the
electric energy of the
system can be improved.
