Document Type and Number:
WIPO Patent Application WO/2022/139030
Kind Code:
A1
Abstract:
In a wind turbine control system using a nacelle lidar and a wind turbine control method using same, the wind turbine control system comprises a nacelle lidar, a calculation unit, and a control unit. The nacelle lidar measures feed-forward wind speed, and feedback and and feed-forward wind directions. The calculation unit includes a wind speed calculation unit which calculates a future wind speed change on the basis of the measurement result of the nacelle lidar, and a wind direction calculation unit which calculates a future wind direction change on the basis of the measurement result of the nacelle lidar. The control unit includes a pitch control unit which controls the pitch of the wind turbine on the basis of the calculation result of the wind speed calculation unit, and a yaw control unit which controls the yaw of the wind turbine on the basis of the calculation result of the wind direction calculation unit.
