Abstract
A gas turbine apparatus has a combustorfor combusting fuel to produce a combustion gas, a turbinewhich is rotated by the combustion gas, an electric generatorcoupled to the turbine, and a fuel flow control valveconfigured to change an opening thereof The gas turbine apparatus includes a first PID processing unitto adjust the opening of the fuel flow control valveso as to maintain a rotational speed of the turbinesubstantially at a constant value, and a second PID processing unitto adjust the opening of the fuel flow control valveso as to maintain a temperature of a discharged combustion gas at temperatures lower than a predetermined temperature. The gas turbine apparatus has an electric power controllerto control electric power to be generated by the electric generatorbased on output values of the first PID processing unitand the second PID processing unit
