Title:
COMPRESSED AIR ENERGY STORAGE POWER GENERATION DEVICE AND COMPRESSED AIR ENERGY STORAGE POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/138764
Kind Code:
A1
Abstract:
Provided is a compressed air energy storage power generation device that preferentially restarts whichever is warmed up from among compressors and electric motors that are stopped, or from among expanders and power generators that are stopped. A compressed air energy storage power generation device 1 comprises: electric motors 10-13; compressors 20-23 that compress air; a pressure accumulation tank 40 that accumulates compressed air; expanders 60-63 that are driven by the compressed air supplied from the pressure accumulation tank; power generators 70-73; and a control device 80 that controls the driving of the electric motors 10-13. The control device 80 includes: a power supply command receiving unit 82 that receives a power supply command; a priority order setting unit 81 that sets a priority order in each electric motor, the priority order being higher as the time from when the electric motor stopped is shorter; an electric motor number determination unit 83 that determines the number of the electric motors 10-13 to be driven on the basis of the amount of input power indicated by the power supply command; and a drive unit 84 that drives the electric motors 10-13 in order of higher priority until the number of the electric motors 10-13 that are driven reaches the number to be driven determined by the electric motor number determination unit 83.
