Abstract :
In order to achieve the ability of primary frequency regulation better, the boiler-turbine coordinated control system for the large capacity unit has become an important research in thermal control field, using the mechanism mathematical model for reference, utilizing the method of pressure node, the dynamic simulation mathematic model of the coordinated control system for supercritical units is given, analyzing and computing the important parameters of the model, including the heat storage coefficient of the evaporating node and the superheating node. Lastly the model is simulated with MATLAB software, through the studies of the simulation curves, demonstrating the validity of the dynamic simulation mathematic model.
