To provide a gas turbine control apparatus, etc. which can effectively suppress combustion fluctuation even if the combustion fluctuation arises in a plurality of frequency bands.
In the case where the combustion fluctuation arises in the plurality of frequency bands, corresponding to a predetermined priority order, adjustment is made so that the combustion fluctuation of the frequency band of a high-priority order is suppressed. In the case where the gas turbine state changes after the adjustment, that is reflected on a database 30. Further, in the case where data is not stocked sufficiently in the database 30 immediately after the gas turbine has been installed, correction is made on the basis of data of countermeasures based on data of another same type gas turbine stored in a basic data base 31 and data of countermeasures based on experiences of skilled adjusting operators stored in a knowledge database 32. Also, in a stabilized operating state, operation condition may be varied so as to automatically search an optimal operation condition.
