Control device for gas turbine, gas turbine facility, control method for gas turbine, and control program for gas turbine

A control device for controlling operation of a gas turbine, comprising:

• a fuel command value calculation unit for calculating a fuel command value to be provided to the gas turbine;
• and
• a motor output setting unit for setting an output set value of a start-up motor of the gas turbine,
• wherein the motor output setting unit is configured to increase the output set value, during startup of the gas turbine and after a switching timing at which the fuel command value calculated by the fuel command value calculation unit switches from constant to continuous increase.

A control method for controlling operation of a gas turbine, comprising:

• a fuel command value calculation step of calculating a fuel command value to be provided to the gas turbine;
• and
• an acceleration rate setting step of setting an acceleration rate set value of a rotor of the gas turbine,
• wherein the acceleration rate setting step includes increasing the acceleration rate set value, during startup of the gas turbine and after a switching timing at which the fuel command value calculated in the fuel command value calculation step switches from constant to continuous increase.

A control program for controlling operation of a gas turbine,

• the control program being configured to cause a computer to execute:
• a fuel command value calculation process of calculating a fuel command value to be provided to the gas turbine;
• and
• an acceleration rate setting process of setting an acceleration rate set value of a rotor of the gas turbine,
• wherein the acceleration rate setting process includes increasing the acceleration rate set value, during startup of the gas turbine and after a switching timing at which the fuel command value calculated in the fuel command value calculation process switches from constant to continuous increase.
