Resumen de: EP4563810A1
A control method for a wind turbine, and a related apparatus. On the basis of acquiring in real time an acceleration parameter corresponding to a target wind turbine, whether the target wind turbine meets a wind regime factor determination condition may be determined, wherein the wind regime factor determination condition is used for determining the reason why yaw vibration of the wind turbine exceeds a limit. If the target wind turbine meets the wind regime factor determination condition, it may be determined that an effective acceleration value of the wind turbine exceeds a vibration limit-exceeding threshold value due to a wind regime factor; and if the target wind turbine does not meet the wind regime factor determination condition, it may be determined that the effective acceleration value of the target wind turbine exceeds the vibration limit-exceeding threshold value due to a yaw brake disc system factor. Therefore, the wind turbine may be controlled on the basis of the accurately analyzed reason for exceeding a limit, so as to avoid performing a frequent shutdown operation owing to exceeding a limit due to the wind regime factor, thereby reducing the startup and shutdown frequency of the wind turbine and reducing the losses.
