Abstract
A wind turbine configured to generate electric energy and feed electric energy to an electric power grid, the wind turbine having a blade assembly; an electric machine having a stator, and a rotor connected to the blade assembly to generate electric energy; a first switch converter connected to the electric machine to control stator electric quantities (I; V); a second switch converter connected to the electric power grid; and a DC link circuit configured to connect the first switch converter to the second switch converter; the wind turbine being characterized by having a control device which, by at least one of the first and second switch converters, controls a direct voltage (V) in the DC link circuit on the basis of an operating parameter of the electric machine indicating the stator voltage (V) of the electric machine, and on the basis of a quantity indicating the line voltage (V) of the electric power grid.
