Abstract
A wind turbine rotor is decelerated and locked in a target rotational position in relation to rotation of the rotor about the rotor axis. The rotational position of the rotor in relation to the rotational axis is detected relative to at least one target rotational position. Once the rotor reaches one of the target rotational positions, the rotor is halted and automatically locked in the target rotational position.
Claims20
A method for the operation of a wind energy installation, comprising:
- decelerating a rotor of the wind energy installation;
- recording the rotational position of the rotor with regard to the rotor axis when the rotor reaches a desired rotational position;
- stopping the rotor in the desired rotational position;
- and
- automatically initiating locking upon reaching the desired rotational position to block the rotor in the desired rotational position with regard to rotation on a rotor axis.
2 more elements
Wind energy installation, comprising:
- a rotor that is rotatable with regard to a rotor axis;
- and
- a locking device to be used for the locking of the rotor in a desired position with regard to the rotor axis, the locking device automatically locking the rotor when the desired rotational position has been reached.
A locking device for a wind energy installation comprising:
- a first locking element configured to connect to a rotor of the wind energy installation;
- a second locking element configured to engage the first locking element locking the rotor;
- and
- a monitoring device configured to determine a relative position of the rotor and to automatically lock the rotor by engaging the first and second locking element when a target rotational position is detected.
