Abstract
The present invention relates to a method for controlled shutdown of wind turbines. The method involves using a generator side converter, and optionally a DC chopper, as a generator load during controlled shutdown. In this way gearbox back-lashing and drive train oscillations can be avoided. The present invention also relates to a wind turbine capable of performing controlled shutdown in accordance with the before-mentioned method.
