Title:
COMPRESSED AIR STORAGE POWER GENERATION DEVICE AND COMPRESSED AIR STORAGE POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/193882
Kind Code:
A1
Abstract:
A compressed air storage power generation device 1 is provided with: a motor 11 which is driven using input electric power; a compressor 10 which is mechanically connected with the motor and compresses air; a plurality of accumulator tank groups 20A, 20B, 20C, 20D which are in fluid connection with the compressor and in which compressed air obtained by the compressor is stored; a plurality of pressure sensors 21A, 21B, 21C, 21D which are provided in the accumulator tank groups and which measure pressures of the accumulator tank groups; an expander 30 which is in fluid connection with the accumulator tank groups and driven by means of compressed air supplied from the accumulator tank groups; a generator 31 which is mechanically connected with the expander; and a control unit 40 which, on the basis of the pressures of the respective accumulator tank groups measured by means of the pressure sensors, determines the order of the accumulator tank groups in which to store compressed air for charging, and determines the order of the accumulator tank groups in which to supply compressed air to the expander for discharging.
