<P>PROBLEM TO BE SOLVED: To provide a method for controlling gas fuel supplied to a gas turbine. <P>SOLUTION: In a fuel control system for the gas turbine, a method for compensating for combustion efficiency includes: a step of forming encoded information on combustor efficiency in a plurality of combustion modes based on a reference parameter in a turbine control system, wherein a fuel demand value signal is provided to the fuel control system by a controller of the turbine control system; a step of sensing combustion mode transfer to an ending combustion mode from a starting combustion mode; a step of calculating the fuel demand value signal for operating conditions under the starting combustion mode of the gas turbine; a step of calculating the fuel demand value signal for operating conditions under the ending combustion mode; and a step of biasing the fuel demand value signal to the fuel control system according to an algorithm, whose technical effect is to correct the combustor efficiency according to the combustion mode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
