摘要
提出模糊自适应整定PID控制理论设计风力发电系统变桨距控制器。建立了风机及变桨距机构模型,以发电机转速测量值,发电机转速测量值与额定转速相比后误差为输入设计控制器。在随机风作用下对设计的模糊自适应整定PID控制器进行仿真,结果表明基于模糊自适应整定PID控制理论的变桨距控制器具有良好的动态性能及对风速扰动的鲁捧性,能够有效改善风力发电系统变桨距控制效果。
Aiming at variable speed constant frequency （VSCF） system, a new pitch controller based on fuzzy self-learning emendation control theory is proposed to improve the power-output quality of VSCF. By using generator rotate speed and speed error as input value, it sets up fuzzy self-learning emendation controller. Besides, this paper carries out simulation of the controller under random wind speeds. The result shows that the controller produces good dynamic performance, good robustness and adaptability.
