    • A compressed air energy storage power generation device 2 includes a compressor 6, a pressure accumulator tank 8, and an expander 10. The compressor 6 compresses air by being driven with renewable energy. The pressure accumulator tank 8 stores the air compressed by the compressor 6. The expander 10 is driven by the compressed air. A power generator 36 is mechanically connected to the expander 10 and generates electric power, which is to be supplied to a demander. The compressed air energy storage power generation device 2 includes: first heat exchanges 16 for recovering compression heat; temperature sensors 29a to 29c that measure the temperatures of the heat media having the temperature increased by the first heat exchangers 16; high-temperature heat medium tanks 19 and 20, each of which individually stores the heat medium depending on the temperature thereof; second heat exchangers 22 for heating compressed air; a low-temperature heat medium tank 21 that stores the heat medium having the temperature decreased in the second heat exchanger 22; and a control unit 40 that switches high-temperature heat storage switching valves 31a and 31b to thereby supply the heat medium from the first heat exchangers 16 to either of the high-temperature heat medium tanks 19 and 20. Thus, the compressed air energy storage power generation device 2 can prevent the high-temperature heat medium from mixing with the low-temperature heat medium.

    • The invention provides a solar/air turbine generator system that reduces construction and power generating costs and does not require the use of fossil fuel.
      A solar/air turbine generator system comprises: a compressor 1 for drawing in and compressing air; a solar receiver 29 for heating the air compressed by the compressor 1 with the use of solar heat collected by a solar collector; an air turbine 2 for driving the compressor 1 and a generator by receiving the compressed air heated by the solar receiver 29; a regenerative heat exchanger, located between the compressor 1 and the solar receiver 29, for heating the air compressed by the compressor 1 using the exhaust of the air turbine 2 as a heating medium; and a distribution device, located between the compressor and the regenerative heat exchanger, for distributing the compressed air to the side of the regenerative heat exchanger and to a bypass side, the bypass side being the inlet side of the air turbine. The solar/air turbine generator system further includes a control device for maintaining the air temperature at the inlet of the air turbine at a constant value by adjusting the flow rate of the air turbine exhaust that flows into the regenerative heat exchanger as a heating medium.
