Abstract

The representation of the external grid impedance is a key element in harmonic studies for offshore wind farms. The external grid impedance is here represented by two different approaches: by a simplified impedance model, based on values for short-circuit power and XR-ratio and by locus diagrams given for a range of harmonic orders. Harmonic studies are carried out with these two different representations and their results are compared subsequently, giving information about the specifity of data that is required for assessing the worst case resonances. This analysis provides the basis for defining a procedure for conducting harmonic studies in wind farms that can be used in commercial
project developments.
