Title:
COMPRESSED AIR ENERGY STORAGE POWER GENERATION DEVICE AND COMPRESSED AIR ENERGY STORAGE POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/110684
Kind Code:
A1
Abstract:
A compressed air energy storage power generation device 1 is provided with: a compression/expansion dual-purpose machine 10 having a function to produce compressed air by using electric power and a function to generate electric power by using the compressed air; a pressure accumulation unit 20 for accumulating the compressed air, the pressure accumulation unit 20 being connected with the compression/expansion dual-purpose machine 10 fluidically; invertors 51, 52 for adjusting the number of rotations of the compression/expansion dual-purpose machine 10; a flow adjustment valve 34 for adjusting a volume of the compressed air supplied from the pressure accumulation unit 20 to the compression/expansion dual-purpose machine 10; and a control device 50 for reducing, at a time of receiving an instruction value to reduce a power generation amount of the compression/expansion dual-purpose machine 10, the number of rotations of the compression/expansion dual-purpose machine 10 by the invertors 51, 52, and reducing the power generation amount of the compression/expansion dual-purpose machine 10 by reducing a degree of opening of the flow adjustment valve 34.
