Effect of Icing on Aerodynamic Performance of Horizontal Axis Wind Turbine in Cold Climates

Abstract

Wind turbines in cold climates are defined as wind turbine operating in an environment where the temperature is 0 or lower. In this paper, the aerodynamic characteristics is clarified by the airfoil performance test of icing airfoil model. With the use of these results, numerical analysis was carried out to clearly the influence of icing airfoil on wind turbine performance and load. As result of the analysis, the rated power with icing airfoil is obtained at higher wind speed than rated one, and maximum value of thrust with icing airfoil becomes lower than clean airfoil.
