摘要： A control device for a gas turbine include: a target value calculation part configured to calculate a control target value being a target value of an output of the gas turbine; and a command value calculation part configured to calculate a fuel command value on the basis of a deviation between the control target value and an actual output value of the gas turbine. The target value calculation part is configured to: set the control target value to a value which is greater than an output demand value of the gas turbine immediately before a difference between the output demand value and the actual output value becomes not greater than a threshold; and subtract the control target value from the value after the difference becomes not greater than the threshold.

摘要： A first fuel flow rate command value indicating a command value CSO of a fuel input amount is calculated so that the output of a gas turbine matches a target output. An upper limit value of the first fuel flow rate command value is calculated. The upper limit value of the first fuel flow rate command value is calculated on the basis of a deviation obtained by subtracting from an estimated value of the turbine inlet temperature of the gas turbine a second limit value relating to the estimated value set such that the estimated value does not exceed the first limit value of the turbine inlet temperature.

摘要： A control device controls a temperature of a shaft seal portion provided around a rotating shaft of a rotating machine to an appropriate temperature by adjusting an amount of the cooling air to be supplied to the shaft seal portion. The control device calculates a sensitivity indicated using the temperature of the shaft seal portion with respect to a flow rate of the cooling air supplied to the shaft seal portion and controls the flow rate of the cooling air so that the sensitivity has a predetermined target value on the basis of the calculated sensitivity. When the sensitivity is calculated, the flow rate is varied in a predetermined range having a certain flow rate as a center. The sensitivity of the temperature at the flow rate as a center is calculated from the variation in the temperature of the shaft seal portion with respect to the variation in the flow rate.

摘要： An IGV opening command value is corrected to calculate an actual opening equivalent value that indicates an approximate value of an actual opening. A temperature estimation value, for a case where a mixture of fuel and in-flowing air is combusted, is calculated using the actual opening equivalent value, atmospheric conditions, and an output from a gas turbine. A fuel distribution command value that indicates distribution of fuel output from a plurality of fuel supply systems is calculated on the basis of the temperature estimation value. The fuel distribution command value and a fuel control signal command value that indicates the total flow rate of fuel to be output to the plurality of fuel supply systems are acquired, and respective valve openings of fuel flow rate regulating valves of the fuel supply systems are calculated on the basis of the fuel distribution command value and the fuel control signal command value.
