FIELD: power industry.
SUBSTANCE: invention relates to power engineering. The mode of operation of the gas-turbine plant containing the compressor, the turbine and the combustion chamber with group of starting burners, group of the burners with pre-mixing consuming the enriched fuel-air mix and group of burners with pre-mixing consuming the diluted fuel-air mix in conditions of change of composition of supplied gas fuel, and the named method includes the following stages: continuous measurement in real time of gas fuel composition, regulation of performance parameters of the named gas-turbine engine and burning of fuel in the named burners using the named measurements of gas fuel composition in real time. Also the gas-turbine installation for implementation of the method according to the invention is presented.
EFFECT: invention allows to ensure functioning of the plant in optimum range, and also to provide optimum effect of reduction of harmful emissions, optimum pulsation characteristics and reliability of operation of the gas-turbine engine.
