Claim 0:
1. A method of controlling a wind turbine, the wind turbine comprising a rotor, a rotor arresting device, a rotor blade, a blade angle detection sensor and a central controller, the method comprising:
in a first operating mode, when the wind turbine is connected to an electrical supply grid and delivers energy to the electrical supply grid:
controlling operation of the wind turbine using the central controller;

in a second operating mode, when the wind turbine is not connected to the electrical supply grid:
connecting a construction aid in the form of a mobile controller to the wind turbine, wherein the construction aid includes an electrical power supply and a controller,
deactivating a control of the rotor arresting device by the central controller,
activating the construction aid to control the rotor arresting device,
detecting a blade angle of the rotor blade,
outputting the detected blade angle to the construction aid, and
blocking an unlocking of the rotor arresting device using the construction aid in response to the detected blade angle not being within a predetermined blade angle range, and

disconnecting the wind turbine from the construction aid and connecting the wind turbine to the electrical supply grid to activate the first operating mode.
