Abstrakty
The paper presents the hybrid model of the conventional power unit. The model contains following fragmentary models: model of the boiler, turbine and regenerative heat exchangers. Fragmentary models have been elaborated with the application of the analytical modelling methods, regression and neural networks. Hybrid model of the boiler contains balance model compatible with the German norm DIN and regressive models describing content of the unburnt combustibles in the slag and in the dust and the neural model describing the flue gases temperature at the outlet of the boiler. Model of the turbine contains balance model and theoretical-empirical model of the steam expansion line in the turbine. Models of the heat exchangers contain the balance and empirical models describing the heat transfer. The paper presents the exemplary calculation results and their comparison with the measurements.
W pracy przedstawiono model hybrydowy bloku energetycznego. Model obejmuje modele cząstkowe: kotła, turbiny i regeneracyjnych wymienników ciepła. Modele cząstkowe opracowano, wykorzystując metody modelowania analitycznego, regresyjnego i neuronowego. Model hybrydowy kotła obejmuje model bilansowy zgodny z normą DlN oraz modele regresyjne opisujące zawartość części palnych w żużlu i w pyle oraz model neuronowy opisujący temperaturę spalin odpływających z kotła. Model turbiny obejmuje model bilansowy i model teoretyczno-empiryczny linii rozprężania pary w turbinie. Modele wymienników obejmują modele bilansowe i modele empiryczne opisujące przepływ ciepła. W pracy przedstawiono przykładowe wyniki obliczeń i ich porównanie z wynikami pomiarów.
