Title:
COMPRESSED-AIR-STORING POWER GENERATION DEVICE AND COMPRESSED-AIR-STORING POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/104222
Kind Code:
A1
Abstract:
A compressed-air-storing power generation device 2 is provided with a first heat exchanger 16, a heat storage tank 20, a second heat exchanger 18, a heater 22, a first power distributor 24, and a control device 26. The first heat exchanger 16 performs heat exchange between a heat medium and compressed air from a compressor 6. The heat storage tank 20 stores the heat medium with which heat has been exchanged by the first heat exchanger 16. The second heat exchanger 18 performs heat exchange between compressed air from an accumulator tank 8 and the heat medium in the heat storage tank 20. The heater 22 heats the heat medium using electric power from a power generator 12. The first power distributor 24 distributes the electric power generated by the power generator 12 to an electrical grid 25 and the heater 22. When the internal pressure of the accumulator tank 8 reaches a prescribed pressure and the generated electric power is greater than the power demand, the control device 26 performs a control for supplying some or all of the generated electric power from the first power distributor 24 to the heater 22. Therefore, the power generating efficiency of the compressed-air-storing power generation device 2 is improved, and equipment costs can be reduced.
