| 摘要: |
| 针对变速变桨风力发电系统随机扰动大、多工况运行、结构时变的复杂系统控制问题，以风机的输出功率、转速和桨距角为研究对象，提出了一种基于混杂自动机的变速变桨控制模型。充分考虑到系统变速和变桨过程中的耦合关系，将控制过程分成4个阶段，结合预估控制给出了各阶段控制器的算法。利用MATLAB／Simulink对某额定功率为1 300 kW的变速变桨风力机组进行建模和仿真，结果表明与传统控制方法相比，采用该建模和控制方法，既改善了风力机输出电能质量，也提高了变速变桨风力发电系统的风能利用效率。 |

| Abstract: |
| A control model based on hybrid automata is proposed for the complex system of VSVP （Variable-Speed Variable-Pitch） wind power generation with big random disturbance，multi-state operation and time-varying structure，which takes the output power，rotor speed and pitch angle as the main study objects. With fully consideration of the coupling relationship between variable-speed control and variable-pitch control，the control process is divided into four stages and the control algorithm combined with the estimation control is given for the controller of each stage. The simulation model of a 1 300 kW VSVP wind power generation system is established with MATLAB／Simulink toolbox and the simulative results show that，with the proposed control model，higher wind power utilization efficiency and better power quality are achieved. |
