A gas turbine in which a centrifugal compressor which is driven by a high-pressure turbine and a variable inlet guide vane located at the inlet of the centrifugal compressor are provided, but an axial-flow compressor is not provided between the centrifugal compressor and the variable inlet guide vane, and an operating method of a gas turbine in which the output is varied by moving the variable inlet guide vane while keeping the speed of engine rotation at a high level near its rated value. It is possible to vary the output in a short period of time and d...
