Abstract

The 2-µm pulsed Doppler lidar of the DLR (Deutsches Zentrum für Luft- und Raumfahrt) was used to carry out wake measurements of a 5 MW wind turbine of the type Multibrid M5000. This prototype offhsore wind turbine is operating in Bremerhaven at a site near the coast line. The maximum range of the lidar is more than ten kilometres and thus we were able to cover the wind field area of inflow, near-wake and far-wake. For data acquisition a range of 2.5 kilometers, which includes more than ten diameters downstream, was used. First results of different scanning techniques, which demonstrate the potential of this type of measurements, will be presented.
