Abstract
The present invention relates to a method of determining the direction of the wind by a LiDAR sensor (2). This method comprises performing measurements by the LiDAR sensor (2), deducing a Gaussian distribution of the longitudinal (u) and transverse (v) components of the wind speed, and determining wind direction (θ) by a spherical cubature approximation method and of the Gaussian distribution of the longitudinal and transverse components of the wind speed.

A method for determining the wind direction by use of a LiDAR sensor arranged on a wind turbine, comprising steps of:
- a) performing wind measurements by use of the LiDAR sensor in at least one measurement plane upstream from the wind turbine, the measurement plane being perpendicular to a measurement direction of the LiDAR sensor;
- b) determining a Gaussian distribution of longitudinal and transverse components of wind speed by use of the measurements, the longitudinal component corresponding to the measurement direction of LiDAR sensor, and the transverse component corresponding to a direction perpendicular to the measurement direction of LiDAR sensor;
- and
- c) determining in real time the wind direction by use of the determined Gaussian distribution of the longitudinal and transverse components of the wind speed through a spherical cubature approximation method.
