Abstract

A wind turbine comprises at least one vane which has a rigid inner vane portion (2) and an outer vane portion (3) which is rotatable in relation to the axis of the vane for controlling the power output of the wind turbine. An auxiliary turbine (20) is provided on each turbine vane at a distance from the shaft (30) of the wind turbine to be exposed to a wind velocity substantially corresponding to the rotational velocity of the auxiliary turbine (20) around shaft (30). The auxiliary turbine (20) is adapted to act upon means controlling the angular position of the vane top (3) in particularly the emergency angular position of the vanes of the wind power rotor.
