摘要： PURPOSE:To permit smooth and rapid starting operation by igniting a high-pressure combustor and a low-pressure combustor in succession and controlling a low-pressure shaft towards speed increase, after a high-pressure shaft is controlled towards speed increase. CONSTITUTION:When a high-pressure turbine 5 and a low-pressure turbine 8 are started separately and a prescribed ignition revolution number is reached, an ignition signal is sent into the fuel control valve 14 of a high-pressure combustor 4. Then, an ignition signal is sent into the fuel control valve 15 of a low-pressure combustor 7. After ignition, each opening degree of the fuel control valves 14 and 15 is throttled to the min. value, and after the lapse of a prescribed time, a high-pressure shaft is controlled towards the increase of speed according to the acceleration setting schedule, and then a low-pressure shaft is controlled towards speed increase, aiming at the turbine outlet temp. When a prescribed speed is obtained, incorporation with a power generator 9 system is performed. Therefore, starting operation can be preformed smoothly and rapidly.
