Abstract

The invention relates to a method for operating a power system of a wind turbine. The power system comprises first and second parallel connected DC-to-AC converters (231, 232) and at least one transformer (208), where each transformer comprises a primary section (Wpri) connected to a power line (220), and where the at least one transformer comprises first and second secondary sections (Wsec1, Wsec2) connected to outputs of the respective first and second DC-to-AC converters. The method comprises providing a reactive correction reference, changing first and second reactive powers (Q1, Q2) generated by the respective first and second DC-to-AC converters according to the reactive correction reference, so that one of the first and second reactive powers is increased while the other is decreased with amounts corresponding to the reactive correction reference so that the first and second reactive powers are unequal.
