  • Patent number: 8348609
    Abstract: A method for de-icing a blade of a wind turbine after the wind turbine has been idle for a period of time. The method includes the steps of creating a controlled acceleration condition of the blade, and subsequently creating a controlled deceleration condition of the blade, whereby ice is shaken off the blade. A wind turbine including a rotor including at least one blade, and deicing means for de-icing the blade wherein the de-icing means includes actuating means of the wind turbine and wherein the de-icing means further includes control means for performing a method for de-icing a blade. Furthermore, the invention relates to use of a wind turbine.
