本文利用现有的运行和性能数据，估算了在动态研究中用于重型燃气轮机的Rowen模型的参数。这项工作的目的是深入了解模型的各个部分，并引入一个简单而全面的程序来从简单的物理定律中推导出参数，特别关注对动态模型和模拟感兴趣的培训师和学生。一个172兆瓦的简单循环，单轴重型燃气轮机涡轮机和它的可用的操作数据也被提出和研究，用于导出模型的参数。燃气涡轮机参数的近似使用简单的热力学假设，导致与典型值的良好对应。该模型的阶跃响应也模拟了几种情况下，并提出。
In this paper, the parameters of Rowen's model for heavy duty gas turbines in dynamic studies are estimated by use of available operational and performance data. The work is aimed to create insight into various parts of the model and to introduce a simple and comprehensive procedure to derive the parameters out of simple physical laws, focusing especially on trainers and students who are interested in dynamic models and simulations. A 172-MW simple cycle, single shaft heavy duty gas turbine and its available operational data are also presented and studied for deriving the parameters of the model. Gas turbine parameters are approximated by using simple thermodynamic assumptions, resulting in good correspondence with typical values. The step response of the model is also simulated for few scenarios and is presented.
