Title:
GAS TURBINE SYSTEM
Document Type and Number:
Japanese Patent JP2000257449
Kind Code:
A
Abstract:
To quickly and accurately detect abnormality or a sign of abnormality in a gas turbine compressor.
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 efficiency η based on the detection process data, and also calculates a variation Δη of the compressor efficiency η. Then, it diagnoses a gas turbine compressor 1, based on the variation Δη of the compressor efficiency η. A gas turbine operation controller 16 stops the operation, when abnormality diagnosis data is input from the gas turbine compressor diagnosis portion 15.
