Vertical wind profile measurement using a pulsed LIDAR system

To achieve reliable wind resource assessments as well as for an accurate short-term wind power forecast, the vertical wind profile from 40 m to 200 m heigth above the ground has been measured. Measurements have been performed on a real wind farm with a very complex terrain using a remote sensing equipment, specifically a LIDAR one. The importance of taking into account all the wind profile over the swept rotor area of a wind turbine has been analysed. It is proposed to rely more on vertical remote sensing than on the theoretical extrapolation when assessing the vertical profile over a complex terrain.
