Abstract
A method of operating a combined cycle power plant to facilitate increasing an output of the power plant. The method includes discharging a first exhaust gas stream from a gas turbine engine and extracting heat from the first exhaust gas stream via a heat recovery steam generator. The method also includes discharging a second exhaust gas stream from the heat recovery steam generator, pressurizing a first portion of the second exhaust gas stream using a recirculation compressor, and cooling the first portion of the second exhaust gas stream using a first cooler. The method further includes discharging a cooled exhaust gas stream from the first cooler to the gas turbine engine and modulating, via a controller, a flow and a temperature of the first portion of the second exhaust gas stream recirculated towards the gas turbine engine.
