Abstract
A method of controlling a wind turbine transformer (20) is provided. The transformer has a primary side with a primary winding (21) coupled to a power grid (90) and a secondary side with a secondary winding (22) coupled to an electrical power generating system (40) of the wind turbine. The wind turbine transformer (20) further comprises an electronic on- load tap changer (30) having semiconductor switches that are controllable to change a turns ratio of the primary winding (21) to the secondary winding (22) of the wind turbine transformer (20). The method comprises the step of monitoring a voltage on the primary side of the wind turbine transformer (20), a voltage on the secondary side of the wind turbine transformer (20), or both. In response to detecting a change in the monitored voltage, the semiconductor switches of the electronic on-load tap changer (30) are automatically controlled to adjust the turns ratio of the wind turbine transformer (20) to compensate for the change.
