ABSTRACT:
Apparatus and method for governing speed and acceleration of a gas turbine system which includes a trimming unit responsive to the speed of a common shaft connecting a combustion air compressor and a gas turbine, which trimming unit varies the fuel flow to the combustion chamber. The setting of the fuel flow to a new speed is by way of a pressure reducer and actuator piston movable in response to changes in the compressor outlet pressure. A blocking mechanism is provided for blocking out the trimming means during acceleration and deceleration conditions. The actuator piston movable with the compressor end pressure is attached at one end of a pivotal bar which has the other end pivotally connected to a control valve sleeve on a fuel supply valve, while the trimming unit operates to control the position of a pivot intermediate the ends of the control bar in response to a speed governor which acts on a control valve piston slidable within the control sleeve.
