20140116106 | SYSTEM AND METHOD FOR CALIBRATING A WIND VANE OF A WIND TURBINE - A system for calibrating a wind indicator device of a wind turbine of the horizontal-axis type in which a shaft has a portion in a nacelle, the wind indicator device being on an exterior of the nacelle. The system comprises a shaft interface adapted to be positioned on the shaft of the wind turbine in a known manner relative to an orientation of the shaft. An extended body is connected to the shaft interface, the extended body projecting from the shaft interface positioned on the shaft to an exterior of the nacelle. An alignment device is connected to the extended body, the alignment device having a visual indicator at the exterior of the nacelle representative of an orientation of the shaft of the nacelle when the shaft interface is positioned on the shaft in the known manner, whereby a calibration of the wind indicator device is achieved using the visual indicator device. A method for calibrating the wind indicator device is also provided. | 05-01-2014 |
