A METHOD FOR DAMPING EDGEWISE OSCILLATIONS IN ONE OR MORE BLADES OF A WIND TURBINE, AN ACTIVE STALL CONTROLLED WIND TURBINE AND USE HEREOF

摘要

A method for damping edgewise oscillations in one or more blades of a wind turbine includes the steps of detecting if one or more of the blades oscillates edgewise during operation of the wind turbine, and substantially cyclically generating a pitch angle difference between at least two of the blades. Further provided is an active stall controlled wind turbine and use hereof.
