Abstract: A method is provided for replacing a permanent magnet of a generator of a wind turbine from a first position to a second position. A container is provided having a shell and an opening through the shell. The opening defines an open space for storing the permanent magnet. The open space is surrounded by the shell, and the shell having a thickness that provides that the permanent magnet does not come close enough to other magnetic material to exert significant force on it. The method involves placing the permanent magnet from the first position into the container, transporting the container with the permanent magnet to the second position, removing the permanent magnet from the container, and placing the permanent magnet in the second position.

Abstract: A wind turbine and a method of controlling yawing of a wind turbine are provided. A nacelle is mounted rotatable around a first axis by an adjustable yaw angle and a hub is mounted rotatable around a rotational axis. The hub includes a blade rotating around the rotational axis, the blade defining a rotor plane perpendicular to the rotational axis. A channel of the wind turbine has an opening, the opening being located at a predefined distance to the rotor plane. At least one component of incoming wind is guided through the opening and into the channel as air flow. A measuring device is provided for measuring the air flow, the measuring device being connected to a controller. The controller detects a yaw angle error between a direction of the incoming wind and the rotational axis, the yaw angle error being used to adjust the yaw angle of the nacelle.
