Studies on Vertical Axis Wind Turbines Technologies

将单独研究Darrieus型垂直轴风力涡轮机(VAWT)的气动弹性和气动声学行为，并在风力发电场编队中进行。达里厄斯风力涡轮机在20世纪70年代的S时代很常见，但由于振动过大的问题而被淘汰。“智能”控制系统和叶片节距控制抑制振动的进步，以及复合材料叶片结构的出现，使这一概念设计如今重新焕发生机。此外，有必要在更深的水域建设海上风力发电场，以将人口稠密地区附近不可避免的视觉和噪音污染降至最低，这促使该行业考虑使用浮动风力涡轮机。由于其固有的稳定性问题，水平轴风力机不适合浮式安装。

The aeroelastic and aero-acoustic behaviour of Darrieus-type vertical axis wind turbines (VAWT) individually and in wind farm formations will be investigated. Darrieus wind turbines were common in the 1970's but they were phase out due to problems with excessive vibrations. Advances in "smart" control systems and blade pitch control to suppress vibrations and the advent of composite blade structures have revitalized this conceptual design nowadays. In addition, the necessity of building offshore wind farms in deeper water to minimize the unavoidable visual and noise pollution near populated areas have pushed the industry to consider floating wind turbines. Horizontal axis wind turbines are not appropriate to floating installations due to its inherent stability problems.
