PURPOSE:To perform abnormality detection quickly and correctly by comparing a signal from a temperature detector provided on a temperature control system and a signal from a temperature detector independent from the temperature control system and detecting an abnormality of the temperature control operation. CONSTITUTION:A temperature signal from a temperature detector 21 provided on the temperature control system of a gas turbine and a temperature signal from a detector 22 provided independently from the temperature control system are compared and calculated by an arithmetic control unit 26, and when the difference between both temperature signals is a preset value or more, an abnormality of the temperature control operation is outputted on a display unit 28. Accordingly, abnormality detection can be performed quickly and correctly. |
