A wind turbine has a generator (7) with a connected rotor (3) having a hub ( 4) and blades (5) rotatably connected to the hub for adjusting the pitch angle. In a method of operating such a wind turbine under climatic conditions, wher e there is a risk of icing on the blades and no or weak wind, the generator is used as a motor for driving the rotor and the pitch angle of the blades is adjusted to ensure that the resulting wind substantially hits the leading ed ge of the blades. Any ice formed may be removed by means of de-icing in a known manner. |
