This article presents a methodology to estimate and validate the aerodynamic properties of a wind turbine from a blade scan. The estimation process is performed by calculating aerodynamic coefficients of different blade sections with numerical simulations while the validation process is done by generating the turbine’s power curve from the aerodynamic coefficients and comparing the power to measurements. First of all, a scan is performed on one blade from which a point cloud is generated. Then, regularly spaced sections of the blade can be extracted and used as a basis to discretize the blades of the turbine. Thanks to a CFD (Computational Fluid Dynamics) code, it is then possible to run simulations allowing the estimation of the aerodynamic coefficients for all the sections. Finally, the computed coefficients are used in a BEM (Blade Element Momentum) model to estimate aerodynamic forces and therefore the power generated by the turbine. Results are compared with SCADA (Supervisory Control And Data Acquisition) data to validate the presented methodology. A very good correlation is observed which encourages the possibility of using a blade scan in the estimation of the aerodynamic properties of a wind turbine.
