Abstract
An arrangement for determining a d-component (Idref, I*d) of a reference current in a d-q coordinate system for reducing noise of a wind turbine, the arrangement including a noise/vibration determination module for determining noise/vibration components of oscillations of at least one wind turbine component, and a processing block for calculating a first type of the d-component of the reference current based on the noise/vibration component output by the noise/vibration determination module, is provided.
