# 锅炉汽水系统Modelica建模与模型标定Boiler Water-Steam System Modeling and Calibration Based on Modelica

Abstract: In order to analyze the nonlinear properties of boiler water-steam system, second-order and fourth-order model is presented by using object-oriented and acausal modeling language, Modelica, and the corresponding simulation is made on the platform of Dymola. For calibrating the model parameters which cannot be measured directly, the residual sum of squares between simulation results and measured data from a real device is calculated and the minimum is taken as the criterion based on pressure and water level responses to a step in fuel flow rate of 10MW at medium loads. After calibrating, the reliability of the model is improved.
