<p>PROBLEM TO BE SOLVED: To provide a method and a device for diagnosing gas turbine operating state, with which the performance deterioration or fault occurrence of a gas turbine can be highly accurately detected. SOLUTION: Operation data in the respective parts of a gas turbine G are detected, these detected operation data are standardized, and these standardized operation data are sampled for prescribed time. Then, moving average processing is applied to these sampled data and on the basis of these moving average data, the operating state of the gas turbine G is diagnosed.</p> |
