ABSTRACT:
In a gas turbine apparatus of a premixed gas combustion type, a plurality of fuel supply systems are provided for supplying fuels to a combustion chamber of the gas turbine apparatus after the fuels are mixed with a high-pressure air, and the supply of fuels from the plurality of fuel supply systems is controlled according to programmed patterns which are predetermined for the fuel supply systems. According to a variation of the turbine load, the patterns of fuel supplies are executed in a transferred manner at a number of transfer points along a variation of the turbine load, with equal amounts of fuel reduced and increased stepwisely in the precedingly and subsequently executed patterns at each of the transfer points.
