Results of Sexbierum Wind Farm; double wake measurements at 1.5D, 2.5D and 4D
report
In the framework of the JOULE-0064 ‘Full-scale Measurements in
Wind Turbine Arrays’ in the period between November 1992 - January 1993
measurements have been performed in the Sexbierum Wind Farm. The aim ofthe
measurements is to provide data for the validation of wake and wind farm models,
which are being developed simultaneously, and to provide input data for wind
turbine load calculation programmes.
The campaign concerned measurement of the wind speed, turbulence and shear
stress behind two wind turbines in line, which were at an inter-distance of 5 rotor
diameters. The wind speed sensors were mounted on three masts at 1.5, 2.5 and 4
rotor diameters behind the second machine, respectively.
A database has been compiled containing 1-minute averaged values of the
measured quantities. The database was analysed using a two-dimensional bin
analysis with respect to the undisturbed wind direction and wind speed.
