Abstract:
Inplant sensors in the boiler and turbine units sense present values of a number of physical parameters designated process variables, and of certain control variables. Set points are developed, and deviations therefrom of the control and process variables are calculated. Utilizing a mathematical model, state variable deviations are estimated and translated into corresponding physical parameter estimates, which are used to evaluate model inaccuracy. State variable and model error estimates are translated into desired control deviations, which in turn are combined with fed forward values of the control variable set points. The combined control terms actuate controllers in the boiler and turbine units.
