PROBLEM TO BE SOLVED: To quickly and accurately detect abnormality or a sign of abnormality in a gas turbine compressor. SOLUTION: A data logger 14 acquires detection process data P1, T1, P2, T2, Fx, V,θ, Tc, etc., and outputs these data to a gas turbine compressor diagnosis portion 15. The gas turbine compressor diagnosis portion 15 calculates a compressor efficiencyηbased on the detection process data, and also calculates a variationΔηof the compressor efficiencyη. Then, it diagnoses a gas turbine compressor 1, based on the variationΔηof the compressor efficiencyη. A gas turbine operation controller 16 stops the operation, when abnormality diagnosis data is input from the gas turbine compressor diagnosis portion 15.
