摘要： A method for controlling an operation of a wind turbine. A meteorological condition is received from a meteorological sensor. An operating threshold value is calculated at least in part by applying a continuous function to the meteorological condition. An operation of the wind turbine is controlled based at least in part on the calculated operating threshold value. For example, the wind turbine may be disabled if a current wind speed exceeds a maximum wind speed that is calculated based on an ambient air temperature or ambient air density.

摘要： A method and an apparatus for adjusting a yaw angle of a wind turbine comprising a rotor having a plurality of rotor blades and a hub are provided. The method is adapted for adjusting the yaw angle from an actual yaw angle to a desired yaw angle and comprises the steps of measuring a wind direction at the location of the wind turbine, measuring the yaw angle of the wind turbine and/or determining a wind direction relative to the nacelle orientation, calculating a pitch angle of at least one rotor blade as a function of the measured wind direction and the measured yaw angle and/or the wind direction relative to the nacelle orientation, and adjusting the pitch angle of the rotor blades according to the calculated pitch angle such that a yaw momentum is generated for changing the yaw angle from the actual yaw angle to the desired yaw angle.

摘要： The present invention provides a connecting device adapted for connecting a hub and a main shaft of a wind turbine. The connecting device comprises at least one sensor bolt connecting the hub and the main shaft, wherein a stress detection element is mounted inside the sensor bolt. The stress detection element is adapted to detect a length variation of the sensor bolt and to output a sensor signal indicative of the length variation of the sensor bolt. A signal output device is used for outputting the sensor signal which is indicative of a stress applied to the sensor bolt.
