摘要： A yaw backup system is provided. The yaw backup system includes an energy storage medium for storing auxiliary power. The yaw backup system also includes a yaw controller for coordinating delivery of power from the energy storage medium to a yaw motor for controlling a yaw angle of a wind turbine during grid loss conditions. The yaw controller executes the steps of receiving wind direction signals over time from a sensor, altering a tolerance level of a wind turbine based on changes in the wind direction signals over time and controlling delivery of power to the yaw motor from the auxiliary power of the energy storage medium based on the tolerance level to control the yaw angle for reducing a load on the wind turbine induced by wind.

摘要： Wind turbine having a yaw system that comprises an annular gear, a plurality of motors, and a gear system having a gearbox and a pinion for each of the motors. Each of the gear systems is arranged to transmit a torque from the related motor to the annular gear. Moreover, at least one of the gear systems comprises a rotatable component having a frangible joint between a first part and a second part of the gear system. This joint is adapted to be broken once, during operation, the first part receives a torque from the annular gear that is greater by a predetermined amount than a torque received from the second part, said breaking of the joint causing the first part to be dragged by the annular gear independently from the second part.

摘要： A wind turbine with a rotor comprising one or more rotor blades and a hub, the hub being attached to a nacelle, a yaw system for rotating the rotor to orient it in a wind direction, and one or more line of sight detectors for detecting a component of wind velocity. The one or more detectors are mounted such that they rotate under the action of the yaw system. A control system is coupled to the one or more detectors and is arranged to compare the detected wind velocity component with a wind velocity value and control the yaw system in response to the comparison. The nacelle can be rotated under control of the control system until the yaw error is substantially zero.
