Abstract

In this paper, the aeroelastic characteristics of IEA-15 MW wind turbine under roll condition are studied by using the lifting-line free vortex wake model and geometrically exact beam theory model. The results show that the roll motion of the floating platform causes the fluctuation of blade inflow, and the effect on the tangential inflow is more significant. The fluctuation of inflow velocity will lead to the fluctuation of wind turbine loads. In addition, the difference of inflow velocity between blades will lead to the tilt and yaw moment of wind turbine. Under roll condition, blade deformations will fluctuate significantly as the tangential inflow velocity of the blade will be significantly changed by roll motion, the amplitude of the edgewise deformation is larger than that of flapwise and torsional deformations. In addition, the torsional deformation of the blade will reduce the angle of attack of the blade. The motion of the floating platform may cause the wake distortion of the wind turbine, and the blade deformations may weaken the wake distortion and intensifies the radial expansion of the wake.
