Abstract
A system for de-icing and/or for avoiding an icing of a component of a wind turbine is provided. The system includes a vibrator. The vibrator includes a piezoelectric material and which is adapted to be mounted to at least to a portion of the component, and an electric generator, which is adapted to supply an electric signal to the vibrator, wherein the electric signal causes the vibrator to vibrate and to transfer vibrational energy to at least a surface portion of the component. A corresponding method for de-icing and/or for avoiding an icing of a component of a wind turbine is also provided.
