Nonlinear modeling and simulation for large scale coal-fired power unit

On the basis of analysis to the boiler models that have exist, the modeling method and simulation environment for large-scale coal-fired power unit are discussed. The power unit is divided into many parts; a set of dynamic model library of thermal equipment and subsystem is setup on with modularization modeling method. The simulation environment is selected as MATLAB/simulink and S-function is used. The integrated dynamic model of 300 MW coal-fired power unit is set up in simulink.
