Abstract :
The nonlinear dynamic boiler model of 300 MW power unit is given which is derived from a mass and energy balance relationship. The parameters of the model can be obtained from the physical dimensions and characteristics of the boiler. The inputs of the model are feedwater valve position, steam valve position, fuel valve position, and feedwater temperature, the outputs of the model are drum pressure, water level, main steam flow. The model can be used for synthesis of model-based control algorithms of a boiler system. It can also be used for setting up a real-time simulator for testing a new boiler control system and operator training
