摘要

根据独立变桨控制（IBP）策略,开发一套基于空间连杆机构的风力机独立变桨控制系统,搭建计及独立变桨控制的浮式风力机（FWT）一体化试验系统,研究统一变桨控制（CBP）和独立变桨控制下的浮式风力机动力学响应特性。结果表明：相较于统一变桨控制策略,独立变桨能有效减小浮式平台纵摇、降低风力机塔顶推力和塔底弯矩等结构载荷,在所研究的工况下减载效果可达10%以上;但同时独立变桨控制也会加剧平台纵摇波动和结构动态载荷,可能引起结构的疲劳损伤。

Abstract

An individual blade pitch controller（IBP） is designed and manufactured for a floating wind turbine（FWT） model. An integrated experimental apparatus of FWT with IBP is established. Extensive tests are conducted to evaluate the performance of the proposed IBP, with collective blade pitch control（CBP） as a reference. The mechanical response characteristics of floating wind turbine under collective pitch control and independent pitch control are studied. The results show that the IBP can effectively reduce the mean values of platform pitch, tower top thrust and tower base bending moment, and the load reduction can reach more than 10% under the conditions studied in this paper. However, the IBP increases the fluctuations of platform motions and structural loads, which may cause fatigue damage to the structure.
