Abstract: The present application provides an energy control computing device for adjusting one or more steam flow parameters delivered to a steam turbine from a heat recovery steam generator via a number of control devices. The energy control computing device includes a processor in communication with a memory. The processor is programmed to receive a number of measured operating values, identify steam turbine operating limits, identify a number of candidate operating modes meeting steam turbine operating limits, selecting the candidate operating mode maximizing the steam flow parameters while not exceeding the steam turbine operating limits, and directing the control devices to meet the selected candidate operating mode.

Abstract: A combined cycle power plant including a gas turbine engine having a compressor inlet and a turbine outlet that is configured to discharge a first exhaust gas stream therefrom. A heat recovery steam generator is configured to receive the first exhaust gas stream, extract heat from the first exhaust gas stream to make steam, and discharge a second exhaust gas stream therefrom. A steam turbine is configured to discharge a steam stream therefrom, a carbon capture system is configured to receive the steam stream, a recirculation blower is configured to pressurize a portion of the second exhaust gas stream for recirculation towards the compressor inlet, and an air inlet blower is configured to pressurize an airflow stream channeled towards the compressor inlet, such that a pressurized mixed flow stream, formed from the portion of the second exhaust gas stream and the airflow stream, is received at the compressor inlet.

Abstract: Various embodiments include a system having: at least one computing device configured to tune a set of gas turbines (GTs) by performing actions including: commanding each GT in the set of GTs to a base load level, based upon a measured ambient condition for each GT; commanding each GT in the set of GTs to adjust a respective output to match a nominal mega-watt power output value, and subsequently measuring an actual fuel flow value and an actual emissions value for each GT; adjusting at least one of a fuel flow or a water flow for each GT to an adjusted water/fuel ratio in response to the actual emissions value deviating from an emissions level associated with the base load level, while maintaining the respective adjusted output; and adjusting an operating condition of each GT in the set of GTs based upon a difference between the respective measured actual fuel flow value and a nominal fuel flow value at the ambient condition, while maintaining the adjusted water/fuel ratio.
