Response Analysis of a Medium-size Wind Turbine on the Effects of Cold and Iced Condition

Abstract

The response of a medium-size wind turbine in cold climate was analyzed considering low temperature and icing, in order to clarify how they affect the results. The increase in the mass of the blades by icing increased the axial force at blade root. The eccentricity due to icing of two blades might have caused unstable rotation and larger fluctuations of the rotor power.
