SYSTEM AND METHOD FOR CONTROLLING A WIND TURBINE

The invention relates to a system and a method for controlling a wind turbine. Accordingly, a controller of the wind turbine detects a loss of traction of a sliding coupling between a rotor of a driveline of the wind turbine and a generator. In response to detecting the loss of traction, the controller overrides the generator torque setpoint to alter the speed of the generator. The tractive force of the sliding coupling is increased in response to the changed rotational speed of the generator. Increasing the tractive force of the sliding coupling facilitates the application of generator torque to the drive train of the wind turbine. 本发明涉及用于控制风力涡轮的系统和方法。因此，风力涡轮的控制器检测风力涡轮的传动系的转子与发电机之间的滑动联轴器的牵引力的损失。响应于检测到牵引力的损失，控制器对发电机转矩设定点超驰，以变更发电机的转速。响应于发电机的经变更的转速，滑动联轴器的牵引力增大。增大滑动联轴器的牵引力促进将发电机转矩施加到风力涡轮的传动系。
