The paper focuses on variable-rotor-speed/variable-blade-pitch wind turbines operating in the region of high wind speeds, where control is aimed at limiting the turbine energy capture to the rated power value. A robust sliding mode approach is proposed, using the blade pitch as control input, in order to regulate the rotor speed to a fixed rated value, in the presence of uncertainties characterizing the wind turbine model. Closed loop convergence of the overall control system is proved. The proposed control solution has been validated on a 5-MW three-blade wind turbine using the National Renewable Energy Laboratory (NREL) wind turbine simulator FAST (Fatigue, Aerodynamics, Structures, and Turbulence) code. A comparison with the standard FAST baseline controller (NWTC 2012 and Jonkman et al. 2009) has been also included.
本文聚焦于在高风速区域运行的可变转子速度/可变叶片桨距风力涡轮机，在此区域控制旨在将涡轮机的能量捕获限制在额定功率值。提出了一种鲁棒滑模方法，将叶片桨距用作控制输入，以便在风力涡轮机模型存在不确定性的情况下将转子速度调节到固定的额定值。证明了整个控制系统的闭环收敛性。所提出的控制解决方案已在一台5兆瓦三叶片风力涡轮机上使用美国国家可再生能源实验室（NREL）的风力涡轮机模拟器FAST（疲劳、空气动力学、结构和湍流）代码进行了验证。还包括了与标准FAST基线控制器（NWTC 2012和Jonkman等人，2009）的比较。
