Abstract
A wind park, a method of correcting voltage imbalances, and a wind turbine are provided. The wind park includes at least one wind turbine; a transformer coupled between the at least one wind turbine and a power grid. The transformer includes a primary winding arrangement coupled to the power grid, and a secondary winding arrangement coupled to the at least one wind turbine. The power grid includes at least three power lines, each power line conducting a respective phase of a multi-phase current. Each power line of the power grid is coupled to the primary winding arrangement via an individual tap changer. Influences of the detected voltage imbalances on the wind turbines can be compensated.
