PROBLEM TO BE SOLVED: To enhance accuracy of detecting abnormality in a plurality of combustion devices mounted on a gas turbine.;SOLUTION: A method for detecting gas turbine abnormality executes: an outlet temperature monitoring process (S12) to monitor temperature distribution in a circumferential direction at outlet section of a turbine where combustion gas is exhausted; and a combustion device abnormality confirmation process (S16), when detecting that one region in the circumferential direction has an abnormal temperature compared to the other region in the outlet temperature monitoring process (S12), to confirm whether or not the region with the abnormal temperature moves according to a change in gas turbine output and to determine, if the region with the abnormal temperature moves, that a combustion device, among a plurality of combustion devices, corresponding to the region with the abnormal temperature has abnormality.;COPYRIGHT: (C)2016,JPO&INPIT
