A control system (130) for use with a turbine engine (100) that is configured to operate at a rated power output is provided. The control system includes a computing device (200) that includes a processor (214) that is programmed to calculate an amount of fluid to be supplied for combustion in the turbine engine. The processor is also programmed to designate at least one nozzle of a plurality of nozzles to receive the fluid. Moreover, the control system includes at least one control valve (201) coupled to the computing device. The control valve (201) is configured to receive at least one control parameter from the computing device (200) for use in modulating the amount of the fluid to be channeled to the nozzle such that the rated power output is generated while emission levels are maintained below a predefined emissions threshold level.
