We examined the feasibility on the stall-control of a horizontal axis wind turbines combined with a camber blade and symmetrical blade. The measured lift and drag force could be evaluated by Xfoil analysis and the momentum of the incoming flow. Although the maximum lift of the cambered blade is 175% than that of the symmetrical blade, there is no significant difference in the drag. The output of the wind turbine consisted by the camber blade with the setting angle 12° becomes larger than the symmetrical blade; however, the blade could not stall-control the output. The wind turbine of the symmetrical blade with the setting angle 60° made the stall-control possible at the main flow velocity around 25m/s. Moreover, the wind turbine combined with the camber and symmetrical blade could control the rated power and the cutout speed aerodynamically.
