| 中文摘要: |
| 风能是世界存量大、绿色无污染的可再生能源之一。由于风力机旋转工况复杂，翼型的相对攻角变化剧烈，导致翼型容易失速，风机的风能利用率低。变桨距主动控制技术是目前最常用的提高升力型垂直轴风力机性能的方法。针对近年来变桨距技术的最新研究进展情况进行了综述。通过全面的文献检索和阅读，总结和阐述了不同变桨距控制策略的设计与实现方法，并分析了不同变桨距技术的优缺点。 |

| Wind energy is one of clean and abundant renewable energy sources. Owing to the complex rotating conditions of wind turbine, the relative attack of angle of airfoil varied greatly, which resulted in the stall of airfoil easily. Therefore, the utilization rate of wind energy for wind turbine was low. The active variable-pitch control technology was a common method for the performance improvement of lift-type vertical axis wind turbine. This paper focused on the research progress in variable-pitch technology. Different design and implementation methods of variable-pitch control technology were summarized. The advantages and disadvantages of these technologies were analyzed. |
