FIELD: fuel.
SUBSTANCE: invention relates to gas turbine fuel supply method and device. Disclosed is fuel supply into gas turbine combustion chamber control method, containing compressor upstream of combustion chamber, wherein method includes: fuel supply into combustion chamber; production of inlet air pressure at compressor inlet; production of inlet air temperature at compressor inlet; production of outlet air pressure at compressor outlet; production of air takeoff signal, indicating amount of air, not supplied to combustion chamber; estimation of fuel heat input, supplied into combustion chamber, based on inlet air pressure, inlet air temperature, outlet air pressure and air takeoff signal; comparison of estimated heat input with required heat input, to produce error signal; and fuel valve controlling, controlling fuel supply into combustion chamber, based on error signal.
EFFECT: technical result of inventions is increase in gas turbine operation stability.
