摘要/Abstract

摘要： 当风速超出额定风速时，大型风电机组通常采用变桨距的控制方式，通过调整叶片桨距角，改变气流对叶片的攻角，从而改变风电机组获得的空气动力转矩，实现对额定功率的稳定追踪。结合模糊控制与PI（比例-积分）控制，分别设计了模糊PI与模糊增益调度PI 2种变桨距控制器，并在Simulink软件环境下，利用Fast软件提供的5 MW陆基风力发电机模型进行仿真实验。仿真表明，新的控制器能有效缩短调节时间，减小系统超调量，具有较好的控制效果。

Abstract: When the wind speed exceeds the rated value, usually the blade pitch controller will be put into the operation of large-scale wind turbine. Specifically, the blade pitch angle is adjusted to maintain appropriate angle of attacking on the blade. Thus, the aerodynamic torque captured from the wind can be regulated to achieve stable power output. In combination with fuzzy control logic and conventional PI control, this paper proposes the design of fuzzy-PI controller and fuzzy gain-scheduling PI controller respectively. Both controllers are applied in the blade pitch control process for the stabilized power output. Under the Simulink-FAST interface, the proposed strategies were tested on a 5 MW onshore wind turbine model. Simulation results show that the novel controller can significantly shorten the time duration for adjustment and reduce the overshoot such that satisfactory control effect can be achieved under the proposed strategies.

Key words: large-scale wind turbine, blade pitch control, fuzzy rule, PI control, FAST software
