PROBLEM TO BE SOLVED: To provide a gas turbine capable of preventing combustion vibration and emission change which may occur upon an anti-icing operation, and to provide a control method of the same.SOLUTION: A gas turbine 1 includes: a compressor 2: a combustor 3; a turbine 4; an inlet guide vane 12 which is disposed on an inlet of the compressor 2, the opening of which is controlled in accordance with a load and which adjusts an air amount flowing into the compressor 2; and an extraction pipe 8 which returns a part of air compressed by the compressor 2 to the upstream side of the compressor 2 upon an anti-icing operation. The gas turbine 1 further includes a controller 5 which controls the opening of the inlet guide vane 12 so as to compensate the air amount to be returned to the upstream side of the compressor 2 via the extraction pipe 8 upon the anti-icing operation. |
