Developpement d'un outil, par simulation numerique, d'aide a la decision pour le positionnement des eoliennes en terrain complexe

The wind industry is growing in Quebec and flat land are increasingly rare. However, the wind resource is far from being exploited to its maximum. Potential sites for new wind farms are increasingly located in complex terrain. Traditional linear tools to assist wind turbines siting decision, as WaSP Engineering, are then out of their usage limit. This thesis focuses on the simulation of the atmospheric boundary layer by the finite volume method and the development of a post-processing tool. It is part of efforts to better understand and extract the wind resource in complex terrain. In this tool, the IEC 61400-1 standard is used to determine some parameters relevant to wind turbine siting from simulations with a two-equation turbulence model. The simulations are compared to wind tunnel measurements. The results of the developed tool are also compared with the results of WaSP Engineering. The proposed method provides an improvement over WaSP Engineering on the evaluation of parameters of interest in complex terrain.
