摘要
对负荷扰动工况下结构复杂的非线性水轮机调速系统进行了仿真实验研究。在Simulink环境下搭建了系统仿真模块,实验内容主要是不同调速器参数及被控系统参数的调节。实验结果表明:参数选取决定了系统动态特性的优劣,合适的参数组合可使系统在一定程度上获得最优的动态性能。学生通过Simulink仿真实验,可以提高仿真实验能力,并进一步掌握水轮机调速系统的结构和动态性能。
The simulation experiment research is conducted on the complex nonlinear water turbine governing system under load disturbance condition. The mathematical model is set up in the Simulink environment, and the experiments of adjusting for the systems with different parameters of governor and controlled system are carried out. The experimental results indicate that the parameters selection determines the performance of the system dynamic characteristics and the suitable parameter combination can make the system obtain the optimal dynamic performance to a certain extent. By the Simulink experiments, the students can not only improve the ability of the simulation, but also grasp the structure and properties of turbine governing system further.
