WIPO Patent Application WO/2022/166144
Kind Code:
A1
Abstract:
A yaw control method and apparatus, an electronic device, and a storage medium. The method comprises: upon detecting that the wind direction changes, if the yaw overload protection state of a wind turbine satisfies a preset condition, controlling a hydraulic brake to be released; after the hydraulic brake is released, if the yaw pressure is less than a first threshold, controlling a yaw motor to be turned on for yawing; and after the yaw motor is turned on for yawing, if the yaw current is greater than a second threshold, controlling the yaw motor to stop yawing.
