FIELD: energy.
SUBSTANCE: invention relates to energy. Method of operating a gas turbine power plant with flue gas recirculation, depending on the operational state of the gas turbine is used to determine the predetermined concentration of the at least one component in an exhaust gas stream and / or in the intake stream of gas turbine exhaust gas after mixing. In addition, measured is the actual concentration of the at least one component in the exhaust gas stream and / or the intake flow and the control element is controlled to adjust the recirculating flow, depending on the deviation of the actual from the desired concentration. In the gas turbine power plant with flue gas recirculation comprises a regulator, which specifies the predetermined concentration of the at least one component in an exhaust gas stream and / or the intake flow of the gas turbine, and a measuring device for measuring the actual concentration of at least one component.
EFFECT: invention improves the reliability of operation of the gas turbine power plant.
