摘要/Abstract

摘要： 针对目前独立变桨距风力发电机存在桨叶受力载荷过大、输出功率和电压不稳定的问题,采用模型参考自适应控制方法进行控制器优化,研究了风力发电机独立变桨优化控制问题。讨论了模型参考自适应控制方法下参考模型选取的过程,根据Lyapunov稳定性理论对模型参考自适应控制器进行了设计,并将这一控制器应用在风力发电机的独立变桨距上。仿真结果表明,该控制方法不仅提高了变桨控制器的响应速度和跟踪精度,而且能够稳定输出功率和电压,同时也能够减少各桨叶的拍打震动。模型参考自适应控制器能够应用在风力发电机独立变桨距控制中,控制效果良好。

关键词: 独立变桨, 模型参考自适应, Lyapunov稳定性理论, 系统级模型, 拍打震动

Abstract: According to the problems of over large pitch load and instable output power and voltage of the independent variable pitch wind turbines, the model reference adaptive control(MRAC) method was used to study the optimal control of independent variable pitch of wind turbines. The selection process of reference model was discussed. The controller was designed based on Lyapunov stability theory and applied to the independent pitch. The simulation results show that the control method not only improved the response speed of the pitch controller but also improved the tracking accuracy, and stabilized the output power and voltage. Meanwhile it reduced the blade flapping vibration. The model reference adaptive controller can be used for wind turbine control.

Key words: independent pitch control, model reference adaptive control(MRAC), Lyapunov stability theory, system model, tapping vibration
