<p>Method of operating a wind turbine having a tower (201), a rotor with a plurality of blades arranged on the tower (207-209), one or more pitch systems for pitching the blades, a system (203) for determining an instantaneous representative wind speed, and a system (206,210-212) for determining a distance between a blade (209) and the tower (201). 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.</p> |
