PURPOSE:To grasp causes of failure in starting by discriminating abnormality generating portions on the basis of the signals from fuel flow and turbine inlet temperature detecting means before rated rotational frequency is reached after rated starting time. CONSTITUTION:When a command is given to a starting compressor 6, a pneumatic starter 3 begins to rotate the rotatably drive a compressor 1a and a turbine 1b. After rated starting time, when the rotational frequency detected by a rotational frequency detecting means 5 does not reach the rated rotational frequency, a discriminating means 20 discriminates abnormality generating portions on the basis of signals of fuel flow and turbine inlet temperature detecting means 9, 7. Thus, causes of failure in starting can be immediately grasped.
