摘要
采用多段集中参数模型对具有分布参数特性的回热器建模,简化了由偏微分方程带来的大量计算.应用Matlab/Simlink软件作为仿真平台,采取数值方法求解,对具体回热燃气轮机中的回热器进行了仿真.结果表明,回热器时间常数较大,在回热循环燃气轮机仿真中回热器的热惯性不能忽略,而且是影响系统平衡稳定性的重要因素.
Many segments lumped-parameter model of distributed regenerator is established. The process of calculation of partial differential equations is simplified. The simulation of regenerator of regenerative gas turbines is studied by numerical method under Matlab/Simulink environment. The research shows that the time-constant of regenerator is very big. The heat inertia is an important factor affecting stability of system balance, and can not be neglected in the simulation of regenerative gas turbines. The dynamic behaviors of regenerator will have important indicative effect on the controlling and operating of regenerative gas turbines.
