摘要

以IEA-15 MW风力机为对象

基于涡尾迹模型和几何精确梁模型研究了纵荡工况下叶片形变对风力机性能的影响。结果表明

浮台的纵荡运动所带来的附加速度会改变风力机的入流速度

从而使风力机的载荷出现波动;而相比于固定工况

纵荡工况下风力机的输出功率有所提升

且在考虑叶片柔性后风力机载荷有所下降。此外

在风力机纵荡运动过程中

风力机的载荷对入流速度变化的响应存在延迟

同时叶片柔性形变带来的附加速度会加剧载荷响应的延迟。

Abstract

For large floating wind turbines

the effects of blade flexibility on wind turbine performance cannot be ignored. Based on lift-line free vortex wake model and geometrically exact beam theory model

the effects of blade flexibility on the aerodynamic performance of IEA-15 MW wind turbine is studied in this paper. The results show that the additional velocity brought by the platform's surge motion will change the inflow velocity of the wind turbine

thus causing the fluctuate of wind turbine loads. Compared with the fixed condition

the output power of the wind turbine is increased under the surge condition

while the wind turbine's load is decreased after considering the flexibility of the blade. In addition

there is a delay in the response of the wind turbine's loads to the change of the inflow velocity under surge condition

and the additional velocity caused by the flexible deformation of the blades will aggravate the delay of the load response.
