Abstract
The invention relates to a method for calibrating a model of a wind-turbine rotor comprising a plurality of blade portions, on the basis of measurements (Mes) and of input curves, wherein at least the following steps are carried out: a) on the basis of the measurements taken, associating (Ass), with certain wind speeds, a gear ratio and an angle of orientation of the blades; b) constructing (Cons) modifying curves for lift and drag coefficients (C1_port, C1_train) and determining, for various sets (Jp) of parameters, maps of power coefficients (Cart_P) and of thrust coefficient (Cart_T); c) generating comparative curves of power coefficient (C1_P) and thrust coefficient (C1_T); d) retaining as final modification parameters (Jp_opt), the sets of modification parameters making it possible to minimize a predefined function; e) calibrating (Cal1) the aerodynamic characteristics of the rotor model.
