Abstract
PURPOSE: To properly maintain controls of fuel flow rate in spite of the number of rotation in a gas turbine by providing a means of compensating gains of a regulator to regulate opening degree of a bypass valve juxtaposed to a fuel pump in inverse proportion to the number of rotation in the gas turbine.
CONSTITUTION: A fuel controller controls opening degree SBV of a bypass valve 3 by a proportional integral controller 2 so that fuel flow rate signal GL from a fuel flow rate detector 5 can correspond to fuel flow rate demand signal GD from a gas turbine controller 1. Here, additional installation includes a turbine velocity detector 7, and a subtractor 6 to subtract fuel flow rate deviating signal ΔG from output of this detector 7. And opening degree of the bypass valve 3 is controlled by output of the controller 2 in response to output of the subtractor 6. By doing so, gains of opening degree control in a split valve 3 compensate ΔG which is input of the controller 2 so as to be inversely proportional to the number of rotation in the turbine, to constantly stabilize loop gains.
