摘要
在介绍风力发电机电动变桨距系统的基础上,以实现对桨距角变化的精确控制为目的,对电动变桨距系统进行设计并提出对变桨距系统控制器的设计。针对风力发电系统的非线性、时变和强耦合的特点,将模糊控制引入到变桨距控制中,在高于额定风速的情况下,根据主控制器由风速变化计算出的桨距角变化量,调节桨叶的位置。最后利用Simulink构建整个控制系统,对变桨距系统进行MATLAB仿真。为进一步对风力机电动变桨距系统控制器的优化设计提供参考。
On the basis of the introduction of the electric pitch system of the wind power system, the design of the electric pitch system and its control were proposed in order to realize the exact control of pitch angle. As the wind power system has the features of nonlinear, time changing and coupling, the fuzzy controller as the controller of the pitch system. When the wind speed is higher than the rated speed, the controller adjusts the blade according to the pitch angle calculated by the main controller. At last, the Simulink was used to build the whole system. Offering helps on the controller design of the pitch system in wind power system.
