Title
(EN) WIND TURBINE AND METHOD FOR IMPROVING THE ELECTROMAGNETIC COMPATIBILITY OF A WIND TURBINE
(FR) ÉOLIENNE ET PROCÉDÉ D'AMÉLIORATION DE LA COMPATIBILITÉ ÉLECTROMAGNÉTIQUE D'UNE ÉOLIENNE
Abstract
(EN)
Wind turbine (1), comprising a hollow tower (2) carrying a nacelle (3), and at least one power electronics component (7) emitting electromagnetic waves during operation, in particular an inverter (8) located at the bottom of the tower (2), wherein the tower (2) acts as a wave guide for an electromagnetic wave generated by the power electronics component (7), wherein the tower (2) comprises at least one absorber element (11, 11a-h) at least reducing the transport of the electromagnetic wave of the power electronics component (7) along the tower (2).
(FR)
L'invention concerne une éolienne (1), comprenant une tour creuse (2) portant une nacelle (3), et au moins un composant électronique de puissance (7) émettant des ondes électromagnétiques en fonctionnement, en particulier un onduleur (8) situé au pied du pylône (2), le pylône (2) sert de guide d'ondes pour une onde électromagnétique générée par le composant électronique de puissance (7), le pylône (2) comprenant au moins un élément absorbeur (11, 11a-h) réduisant au moins le transport de l'onde électromagnétique du composant électronique de puissance (7) le long du pylône (2).
