Method for operating a wind energy assembly, for which the risk of icing is determined on the basis of meteorological data and wind energy assembly for implementing the method

摘要

The method involves detecting and storing the meteorological data and determining a freezing risk of a component of the wind turbine (10) based on the detected meteorological data. The meteorological data are collected by detecting the horizontal or vertical vision range and taking the detected vision range to determine the freezing risk. A heating device (32) for component of wind turbine is operated for determining the freezing risk. An independent claim is included for a wind turbine.
