摘　　要：为了提高火电仿真培训系统模型精度和模块运行速度,笔者以三分仓回转式空气预热器为研究对象,提出三分仓空气预热器链式结构集总参数模型,该模型由三个相互重叠的环节组成,分别建立各环节的简单集总参数模型,在烟气热流量、空气入口流量和焓扰动的情况下,其出口焓分别以二阶和三阶的精度逼近分布参数模型,提高了三分仓空气预热器模型的精度。依托MSP多学科仿真开发平台进行图形化建模和仿真,结果表明:该模型具有精度高、建模方法相对简单、运行速度快、模块可移植性好等优点。In order to improve the model accuracy and module operation speed of the thermal power simulation training system,the authors take the tri-sector air heater as the research object,and propose a tri-sector air heater chain structure lumped parameter model.The model consists of three overlapping links,and the simple lumped parameter models of each link are established respectively.In the case of flue gas heat flow,air inlet flow and enthalpy disturbance,the outlet enthalpy approximates the distributed parameter model with secondorder and third-order accuracy respectively,which improves the accuracy of the tri-sector air heater model.Based on the MSP multidisciplinary simulation development platform,graphical modeling and simulation are carried out.The results show that the model has the advantages of high precision,relatively simple modeling method,fast running speed and good module portability.
