Power plant operation enhancement

A power plant control system 230 determines an augmented operating parameter set point responsive to a life cycle cost (LCC) objective function responsive to a LCC model 2313. The augmented operating parameter value may be responsive to an initial set point determined by a controls model 2311 and a...

Beschreibung
Zusammenfassung:	A power plant control system 230 determines an augmented operating parameter set point responsive to a life cycle cost (LCC) objective function responsive to a LCC model 2313. The augmented operating parameter value may be responsive to an initial set point determined by a controls model 2311 and a performance indicator determined by a performance model 2312. The power plant 130 may include a thermal generator, such as a gas turbine or other fuel-burning generator, and the operating parameter may include firing temperature, fuel flow rate, steam pressure/temperature/flow rate, and/or another suitable operating parameter. An offer curve 2325 is generated responsive to the augmented operating parameter.
