A method for controlling at least one train of a stoichiometric exhaust gas recirculation power plant arrangement, comprising the steps of: compressing ambient air into a compressed ambient gas flow with at least one main air compressor ; delivering at least a first portion of the compressed ambient gas flow , with a master compressed ambient gas flow rate, to a master turbine combustor that is fluidly connected to the at least one main air compressor via a first line; compressing a master recirculated gas flow into compressed master recirculated gas flow with a master turbine compressor separate from the at least one main air compressor ; delivering at least a first portion of the compressed master recirculated gas flow to the master turbine combustor from the turbine compressor via a second line separate from the first line; delivering a master fuel stream , having a master fuel stream flow rate, to the master turbine combustor for mixing with the at least a first portion of the compressed ambient gas flow and with the at least a first portion of the compressed master recirculated gas flow to form a master combustible mixture; burning the master combustible mixture in the master turbine combustor and thereby forming the master recirculated gas flow and driving a master turbine connected to the master turbine compressor via a master turbine shaft ; recirculating the master recirculated gas flow from the master turbine to the master turbine compressor using a master recirculation loop ; measuring at least one master emission level by at least a first master emission sensor in the master recirculated gas flow ; using the at least one master emission level measured by the at least a first master emission sensor to generate at least a first master control signal; and adjusting the master fuel stream flow rate based on the at least a first master control signal to achieve substantially stoichiometric combustion. compressing ambient air into a compressed ambient gas flow with at least one main air compressor ; delivering at least a first portion of the compressed ambient gas flow , with a master compressed ambient gas flow rate, to a master turbine combustor that is fluidly connected to the at least one main air compressor via a first line; compressing a master recirculated gas flow into compressed master recirculated gas flow with a master turbine compressor separate from the at least one main air compressor ; delivering at least a first portion of the compressed master recirculated gas flow to the master turbine combustor from the turbine compressor via a second line separate from the first line; delivering a master fuel stream , having a master fuel stream flow rate, to the master turbine combustor for mixing with the at least a first portion of the compressed ambient gas flow and with the at least a first portion of the compressed master recirculated gas flow to form a master combustible mixture; burning the master combustible mixture in the master turbine combustor and thereby forming the master recirculated gas flow and driving a master turbine connected to the master turbine compressor via a master turbine shaft ; recirculating the master recirculated gas flow from the master turbine to the master turbine compressor using a master recirculation loop ; measuring at least one master emission level by at least a first master emission sensor in the master recirculated gas flow ; using the at least one master emission level measured by the at least a first master emission sensor to generate at least a first master control signal; and adjusting the master fuel stream flow rate based on the at least a first master control signal to achieve substantially stoichiometric combustion. <EOS>
