Method for calibrating aerodynamic characteristics of a wind turbine rotor model

Abstract

The invention relates to a method for calibrating a wind turbine rotor model comprising several blade portions, from measurements (Mes) and input curves, in which at least the following steps are carried out: a) from the measurements carried out, a speed ratio and an orientation angle of the blades are associated (Ass), with certain wind speeds. b) modifying curves of the lift coefficients (C1_port) and drag coefficients (C1_train) are constructed (Cons) and mappings of power coefficients (Cart_P) and thrust coefficients (Cart_T) are determined for different sets (Jp) of parameters; c) comparative curves of power coefficients (C1_P) and thrust coefficients (C1_T) are generated; d) the sets of modification parameters making it possible to minimize a predefined function are retained as final modification parameters (Jp_opt); e) the aerodynamic characteristics of the rotor model are calibrated (Cal1).
