Abstract: PROBLEM TO BE SOLVED: To provide a gas turbine device which makes stable motion without generating the overshoot of the temperature of engine combustion emission gas. SOLUTION: The gas turbine device has a gas turbine engine for driving/ rotating a gas turbine by mixing and burning a fuel, and a generator directly connected to the gas turbine. The gas turbine device also has: a sensor for measuring the temperature of combustion emission gas of the engine; a means for reducing the output of the generator at a low speed when the temperature of the combustion emission gas measured by the sensor exceeds a first set value higher than a target temperature; a means for reducing the output of the generator at a high speed when the temperature of the combustion emission gas exceeds a second set value higher than the first set value; and a means for increasing the output of the generator at a low speed when the temperature of the combustion emission gas is lower than a third set value lower than the target temperature.
