摘　　要：提出了在冷热电联产系统中从微型燃气轮机的燃烧室通向透平的管道中抽取燃气进入蒸汽发生器的思想,以微型燃气轮机作为研究对象,建立起带抽燃气微型燃气轮机中各物理部件的数学模型,根据透平负载率和抽燃气率的变化,运用SIMULINK工具对带抽燃气微型燃气轮机变工况运行方式进行了仿真.仿真结果与事实相符,且能正确地反映全工况的动态特性.The paper advanced an idea that extraction gas from the gas pipeline between the combustion chamber and turbine entered the steam generator.Taking the microturbine as the disquisitive object,the paper has been established the mathematical models of each physical part of the microturbine with extraction gas.According to the diversification of the turbine load rate and extraction gas rate,the microturbine with extraction gas operation at off-design condition has been simulated with Simulink.The simulation results prove that the model with favourable heat economy accords with fact and can show the correct dynamic characteristics of the whole conditions.So the model provides a useful reference for the research and applications of the microturbine and CCHP system.
