Abstract

PURPOSE: To achive stable and accurate fuel control by controlling the fuel gas control valve to the value added with the correction for the pressure difference across said valve.
CONSTITUTION: In a gas turbine, the air compressor 1 is led to the burner 2 where it is burnt together with the gas fuel led through speed ratio valve 4 and fuel gas control valve 5 to drive the turbine 3 and to operte the generator 6. Here the pressure in front of said vlave is mesured by pressure detector 9 while the pressure at the back of said valve is measured by pressure detector 11 and the root of pressure difference is calculated by root circuit 20. The output from said circuit 20 is provided to subtractor 19 and corrected by fuel demand signal Gce then its command value and the real value measured by valve opening detector 10 are collated at the regulator 18 to drive the driving end 8 thus to control the opening of fuel gas control valve 5 in accordance with the output form said regulator 18.
