Abstract: A system to control a wind turbine, including meteorological instruments for measuring ambient climatic conditions, and generating corresponding meteorological signals, a memory for storing an icing tolerance, a first calculator for calculating an overall icing probability based on the meteorological signals and a controller for stopping the wind turbine when the overall probability of icing is greater than the icing tolerance. Also disclosed is a method for controlling a wind turbine, including the steps of a) measuring ambient climatic conditions and generating corresponding meteorological signals; b) storing in memory an icing tolerance; c) calculating an overall probability of icing based on the meteorological signals; and d) stopping the wind turbine when the overall probability of icing is greater than the icing tolerance.
