摘要： The present invention provides a compressed air energy storage power generation device that, among stopped compressors and motors or expanders and generators, preferentially restarts a warmed up compressor and motor or a warmed up expander and generator. A compressed air energy storage power generation device 1 includes motors 10 to 13, compressors 20 to 23 that compress air, an accumulator tank 40 that accumulates compressed air, expanders 60 to 63 driven by the compressed air supplied from the accumulator tank, generators 70 to 73, and a control device 80 that controls driving of the motors 10 to 13. The control device 80 includes a power supply command receiver 82 that receives a power supply command, a priority setting unit 81 that sets priority to the motors so that the motor whose elapsed time from stop is shorter has higher priority, a number-of-units determination unit 83 that determines the number of the motors 10 to 13 to be driven on the basis of an amount of input power indicated by the power supply command, and a drive unit 84 that drives the motors 10 to 13 in the descending order of the priority until the number of the driven motors 10 to 13 becomes equal to the number of motors to be driven determined by the number-of-units determination unit 83.

摘要： A compressed air energy storage power generation device 2 equipped with: a compressor 10 mechanically connected to a motor 30; a first pressure storage tank 12 storing compressed air from the compressor 10; an expansion device 14 driven by compressed air from the tank 12; a generator 28 mechanically connected to the expansion device 14; a first heat exchanger 18 that exchanges heat between a heat medium and the compressed air supplied from the compressor 10 to the tank 12; a second heat exchanger 22 that exchanges heat between the heat medium and the compressed air supplied from the tank 12 to the expansion device 14; a pressure sensor 13 that detects the state of charge (SOC) of the tank 12; SOC adjustment units 17, 34a, 34b, and 34c that adjusts the SOC; and a control device 40. The control device 40 controls the SOC adjustment units 17, 34a, 34b, and 34c such that the detected SOC is within an optimal SOC range while satisfying the requested power. Thus, in this compressed air energy storage power generation device 2 the SOC is controlled so as to be within an optimal SOC range, so the operating efficiency can be improved.

摘要： A compressed air storage power generation apparatus 2 is provided with a motor 8a, a compressor 10, a pressure accumulation tank 12, an expander 14, a generator 16, a first heat exchanger 18a and a cold heat extracting unit 13. The motor 8a is driven by input power generated using renewable energy. The compressor 10 is mechanically connected to the motor 8a and compresses air. The pressure accumulation tank 12 accumulates the compressed air compressed by the compressor 10. The expander 14 is driven by the compressed air supplied from the pressure accumulation tank 12. The generator 16 is mechanically connected to the expander 14. The first heat exchanger 18a exchanges heat between the compressed air supplied from the compressor 10 and a heat medium and cools the compressed air to room temperature. The cold heat extracting unit 13 extracts air serving as working fluid as cold air of the room temperature or lower. Due to this configuration, the compressed air energy storage power generation apparatus 2 capable of smoothing input power that varies irregularly and efficiently performing heating and cooling with the input power is provided.

A sub flow passage 13 includes a shortened flow passage 12 which is a part of the heating medium flow passage and branches from the heating medium flow passage between the second heat exchanger 7 and the second heat storage unit 10 and extends to the first heat storage unit 9. The sub flow passage 13 allows circulation of the heating medium between the first heat storage unit 9 and the second heat exchanger 7. A first heating means 22 in a middle of the shortened flow passage 12, the first heating means 22 heating a passing heat medium, and a switching means 20, 21 conducting switching between the main flow passage 11 and the sub flow passage 13 are provided.
