Abstract

A flow ratio calculation device includes: a flow volume ratio computer that, using a predetermined relationship between a first parameter that can express a combustion state in a combustor and a flow volume ratio of fuels flowing through multiple fuel systems, is configured to find the flow volume ratio based on a value of the first parameter; a correction value computer configured to find a correction value of the flow volume ratio when a load of a gas turbine changes; a fluctuation sensor configured to sense fluctuations in a value correlated with the load of the gas turbine; and a corrector configured to correct the flow volume ratio found by the flow volume ratio computer with the correction value found by the correction value computer when a fluctuation in the value correlated with the load of the gas turbine is sensed by the fluctuation sensor.
