Abstract: Method of operating a wind turbine having a tower, a rotor with a plurality of blades arranged on the tower, one or more pitch systems for pitching the blades, a system for determining an instantaneous representative wind speed, and a system for determining a distance between a blade and the tower. The method comprises determining the instantaneous representative wind speed, and determining the distance between the tower and one of the blades when said blade is in the shadow of the tower. The method further comprises determining a tower distance pitch adjustment depending on the determined distance between the tower and the blade in the shadow of the tower and on the determined instantaneous representative wind speed. The method still further comprises the one or more pitch systems applying the determined tower distance pitch adjustment to at least the next blade to be in the shadow of the tower.

Abstract translation: 操作具有塔架的风力涡轮机的方法，具有布置在塔架上的多个叶片的转子，用于俯仰叶片的一个或多个俯仰系统，用于确定瞬时代表性风速的系统，以及用于确定 一个刀片和塔。 该方法包括确定瞬时代表风速，以及当所述叶片处于塔的阴影中时，确定塔与叶片中的一个之间的距离。 该方法还包括根据在塔的阴影中确定的塔架和叶片之间的距离以及确定的瞬时代表风速来确定塔架间距调节。 该方法还包括一个或多个俯仰系统将确定的塔距离俯仰调节应用于至少下一个叶片处于塔的阴影中。
