Abstract: A method and a system for managing loads on a wind turbine are provided. The method includes receiving a signal relative to a yaw misalignment of the wind turbine, generating a yaw error signal based on the yaw misalignment, and comparing the yaw error signal to a first predetermined yaw error threshold value. The method also includes regulating a speed of the rotor to a value determined by a predetermined tip speed ratio, reducing the yaw misalignment using a yaw control system, and restarting the wind turbine if the yaw error signal is reduced to less than a second predetermined yaw error threshold value within a predetermined period of time. The method further includes shutting down the wind turbine if the yaw error signal remains greater than the second predetermined yaw error threshold value beyond the predetermined period of time.

Abstract translation: 提供了一种用于管理风力涡轮机上的负载的方法和系统。 该方法包括接收相对于风力涡轮机的偏航偏移的信号，基于偏航失准产生偏航误差信号，以及将偏航误差信号与第一预定偏航误差阈值进行比较。 该方法还包括将转子的速度调节到由预定的叶尖速度比确定的值，使用偏航控制系统减少偏航偏移，并且如果偏航误差信号被减小到小于第二预定偏转角度则重新启动风力涡轮机 误差阈值在预定时间段内。 该方法还包括如果横摆误差信号保持大于超过预定时间段的第二预定偏航误差阈值，则关闭风力涡轮机。
