摘要： PROBLEM TO BE SOLVED: To increase thermal efficiency within the partial load operating range where the design point is not exceeded, and, in the operating range where the design point is exceeded, increase thermal efficiency in the design point side operating range. SOLUTION: This gas turbine is provided with a compressor 1, a turbine 2, and a combuster 3. In this gas turbine, the compressor 1 is connected to a shaft 4 of the turbine 2, an air outlet of the compressor 1 is connected to the air outlet of the combuster 3, and the gas outlet of the combuster 3 is connected to the gas inlet of the turbine 2. This gas turbine is also provided with a pre-pressurizing air compressor 21 that puts the design point of the gas turbine in the partial load operating range and pressurizes the air taken into the air inlet of the compressor 1 where the design point is exceeded, and a rotary drive unit 22 to drive the pre-pressurizing air compressor 21. This gas turbine further comprises a control unit 28 which obtains the desired output by controlling the pressure ratio of the pre-pressurizing compressor 21 by adjusting the rotational speed of the pre-pressuring compressor 21.

摘要： PROBLEM TO BE SOLVED: To increase thermal efficiency within the partial load operating range in which the design point is not exceeded, and make thermal efficiency approximately the same in the operating range in which the design point is exceeded. SOLUTION: This gas turbine is provided with a compressor 1, a turbine 2, and a combuster 3. In this gas turbine, the compressor 1 is connected to a shaft 4 of the turbine 2, an air outlet of the compressor 1 is connected to the air outlet of the combuster 3, and the gas outlet of the combuster 3 is connected to the gas inlet of the turbine 2. This gas turbine is also provided with a pre-pressurizing air compressor 21 that puts the design point of the gas turbine in the partial load operating range and pressurizes the air taken into the air inlet of the compressor 1, and with a clutch 23 that engages the pre-pressurizing air compressor 21 with the turbine shaft 4 in the operating range where the design point is exceeded. This gas turbine further comprises a control unit 30 which obtains the desired output by adjusting the rotational speed of the pre-pressuring compressor 21.
