Abstract
There is provided a method of controlling a wind turbine on starting or running up the wind turbine before the wind turbine is connected to an electrical supply grid or before the wind turbine is connected to the electrical energy supply grid again. The wind turbine has a rotor having a rotor arresting means, at least one rotor blade and at least one blade angle detection sensor for each rotor blade for detecting the blade angle of the rotor blade. The blade angle of the at least one rotor blade is detected by means of the blade angle detection sensor. Unlocking of the rotor arresting means is blocked until the detected at least one blade angle is within a predetermined angle range. In that way it is possible to ensure that the rotor arresting means is released only when the blades are for example in the feathered position.
