2. Extrapolation of wind speed to nacelle height
In order to estimate the wind energy recovered by the wind turbine wheel, the Weibull parameters k and C are extrapolated from the altitude level z1 of the wind speed measurement to the altitude z2 of the wind turbine nacelle.
In 1976, Justus and Mikhail have proposed, for an initial altitude reference equal to 10 m, the following extrapolation formulas at altitudes z1 and z2 (in m):
