Zusammenfassung:A method for heating a wind turbine facility includes: charging a DC link of an electrical converter connected with a wind turbine of the wind turbine facility; heating air inside the wind turbine facility with heat generated by a voltage limiting unit interconnected with the DC link, which includes a resistor adapted for dissipating electrical energy into heat for reducing a voltage in the DC link, when the voltage is above a threshold voltage; wherein the voltage limiting unit is controlled, such that the voltage limiting unit generates heat according to settings defined in a controller of the voltage limiting unit. The heating settings are changed based upon commands from a user interface. Furthermore, the DC link is charged by a grid side converter of the wind turbine facility with power from an electrical grid.
