More Information
Summary:The invention relates to a method for reducing loads in an aerogenerator when disconnected from the power grid during a wind gust, employing a three-loop control system which can be used to correct the speed at which the blades are moved to the feathered position during a controlled emergency shutdown, using a non-linear law taking account of the position of the blades, the vibration of the tower and the generator rotation speed limits.
