摘　　要：以某电厂6号机组(600MW)为研究对象,为对其调速器系统模型参数进行辨识,设计并实施了相关的试验。在辨识过程中,针对常规参数辨识方法在进行汽轮机调速系统模型参数辨识时所遇到的困难,采用了一种基于遗传算法的模型参数辨识方法,并利用Matlab及其simulink工具箱予以实现。结果表明,该方法较为适用于汽轮机调速系统模型参数的辨识,辨识所得到的模型也达到了较高的仿真精度。Researches the No. 6 steam turbine unit in a power plant. In order to identify the model parameters of its speed governor system, we designed an experiment and carried it into execution. During the process of identification, as to solve the problems of conventional parameter identification methods, when apply to the parameter identification of the steam turbine speed governor system, we adapted a kind of parameter identification method based on the genetic algorithm, and realize it by matlab and its simulink toolbox, Results shows that this method is quite fit for the model parameter identification of the steam turbine speed governor system, the model we got also shows quite high simulation accuracy.
