Abstract

This gas turbine control device comprises: a fuel flow rate command value calculation unit; and a fuel flow rate control unit. The fuel flow rate command value calculation unit calculates a fuel flow rate command value by means of proportional integration control based on the deviation between a gas turbine rotation number and a target rotation number, or the deviation between a gas turbine output and a target output load. The fuel flow rate control unit controls the flow rate of a fuel with respect to a gas turbine on the basis of the fuel flow rate command value. The fuel flow rate command value calculation unit calculates the fuel flow rate command value so that the output of the gas turbine in a first output band increases at a first rate of change, and calculates the fuel flow rate command value so that the output of the gas turbine in a second output band which is higher than the first output band increases at a second rate of change which is smaller than the first rate of change. Further, an integration gain in the first output band of the proportional integration control is set to be smaller than an integration gain in the second output band.

The present invention relates to a rubbing position identification device for a rotating machine provided with a fixed part and a rotating part. This device is provided with an AE sensor, an axial vibration sensor and a rubbing position identification unit. In the case of rubbing occurring in the rotating machine, the rubbing position identification unit calculates the AE phase, which corresponds to the peak of an envelope determined on the base of change over time in the AE signal detected by the AE sensor, and the axial vibration phase, which corresponds to the high spot position of the rotating part specified on the basis of the change over time in the axial vibration signal detected by the axial vibration sensor, and, on the basis of the phase difference between these, identifies the circumferential-direction position of where rubbing has occurred in the rotating machine.
