Abstract

A two-shaft gas turbine 1 of the present invention, in which a mass flow of an air into a compressor is regulated by controlling a set angle of an inlet guide vane (IGV) on an air intake side of the compressor 3, comprises, as a device to control the set angle of the IGV, a first controller 26 to control the set angle of the IGV based on a corrected speed of the gas generator shaft during low speed rotation of the gas generator shaft, the corrected speed having been corrected according to an ambient temperature; a second controller 27 to control the set angle of the IGV to maintain a constant actual speed of the gas generator shaft during high speed rotation of the gas generator shaft; and an ambient temperature correction part 29 to increase the actual speed maintained constant by the second controller 27 if the ambient temperature is equal to or more than a threshold value.
