| 摘 要： | 通过对风轮的受力及风能利用系数进行分析,推导了风能利用系数和风轮转矩的近似表达式,讨论了实现风轮输出特性及转动惯量模拟的方法。使用感应电机对风轮的转矩转速特性进行模拟,同时给出了风轮模拟系统的硬件结构,搭建了实验平台。测试表明,该系统能够实现风轮输出特性的近似模拟,并能较准确地反映出转动惯量对输出特性的影响,为风力发电的研究提供了方便的测试手段。

| Abstract: | Based on the analysis of stress and coefficient of wind turbine, an approximate expression of power coefficient and output torque were deduced. It discussed simulation method of output characteristics and rotational inertia. Furthermore, simulation of induction machine was carried out for the torque and speed characteristics of wind turbine, and the hardware of the simulation system and the experimental platform were provided. Test results show that the system can not only realize the approximate simulation of output characteristics, but also accurately reflect the effect of rotational inertia on the output characteristics, which offers a convenient testing method to the research of wind power generation. |
