Abstract

In this paper, a test scheme of wind turbine coupled with irregular, multi-degree-of-freedom rotating motion is proposed. Through physical model tests, the motion response characteristics of wind turbine under different yaw angles are studied under turbulent conditions. The results show that the rolling motion and pitching motion of wind turbine are low frequency, while the yawing motion is high frequency. In the wind turbine incoming flow, the low-frequency turbulent structure is more likely to cause the floating wind turbine pitching motion, while the high-frequency turbulent structure is more likely to cause the floating wind turbine rolling motion. When the yaw angle of the wind turbine is 0°, the rolling motion is the main advantage among the three rotating motion components of the floating wind turbine, while when the yaw angle of the wind turbine is 30°, the pitching motion is the main dominant rotating motion component. With the increase of the yaw angle, the oscillation amplitude of the roll motion of the wind turbine tends to decrease, while that of the pitch motion tends to increase.
