摘要： The present stress in the turbine rotor is estimated at each control period, from the steam temperature and pressure at the turbine inlet. In addition, the future turbine inlet steam temperature or pressure is preestimated once every n.sub.T control cycles, for a given speed or load changing rate, making use of data concerning the changing rate of the turbine steam inlet temperature or pressure in relation with the change of the speed or load, which has been obtained by a learning of the past turbine operating condition. This future steam temperature or pressure at the turbine inlet is used as a factor for preestimating the future stress expected to be caused in the turbine rotor. The preestimation of the rotor stress is performed for a plurality of assumed speed or load changing rates. The turbine is controlled at the maximum speed increase-rate or load changing rate which would not cause the future stress preestimated over a given preestimation time to exceed a limit stress. An observation of the present stress is made at each control period to check whether the limit stress is not exceeded by the present stress.

摘要： A gas turbine apparatus has a gas turbine and a plurality of burners for providing combustion gas to drive the turbine. A flow control means of each burner for fuel or combustion air is adjusted by control means to control each said burner individually in dependence on a predetermined combustion characteristic of the respective burner. Sensed quantities relating to the combustion performance of the burners are input to the control means which adjusts the flow control means of each burner in dependence on the sensed quantities and the predetermined combustion characteristic of the respective burner.

摘要： Vibrations at a plurality of points on a turbine rotor and vibrations at corresponding points of the turbine stator are measured during a common sampling period for each corresponding points. Consequently, vibration data are obtained for each point on the turbine rotor and for each point on the turbine stator corresponding to the point on the turbine rotor. Then, a correlation coefficient representing the correlation between the vibration data of each point on the turbine rotor and the vibration data of corresponding point on the turbine stator is calculated, and the correlation coefficient is differentiated. The correlation coefficients and the differential values are then compared with respective predetermined reference values. The occurrence of rubbing is detected from the result of these comparisons.
