  • Method of controlling a grid side converter of a wind turbine and system suitable therefore
    Patent number: 9093924
    Abstract: According to an embodiment of the present invention, a method of controlling a grid side converter of a wind turbine is provided, wherein an output of the grid side converter is connected or connectable via a power line to an input of a grid transformer, the method comprising: determining a converter volt-sec occurring at the output of the grid side converter based on a converter voltage occurring at the output of the grid side converter; determining a volt-sec error between the determined converter volt-sec and a converter volt-sec reference, wherein the converter volt-sec reference is determined based on active power reference, reactive power reference, line current and a line voltage occurring at the input of the grid transformer (or at wind turbine terminals); and controlling, based on the determined volt-sec error, the grid side converter such that the volt-sec error is partly or fully compensated.
