This paper presents a comparison between GPS synchronized measurements of two switching operations in Nysted Offshore Wind Farm (NOWF) in Denmark, and results from electromagnetic transient (emt) simulations of these switching events using Power Factory/DIgSILENT and PSCAD/EMTDC. The collection grid of Nysted created in Power Factory and PSCAD was based on the information available from the wind farm as-built documentation. The cable model used in both programs was created based on the geometry and material properties of the cable. Circuit breakers and transformers were modelled by means of the comparable simple standard models in both tools. The results from the simulations in Power Factory and PSCAD match the measured steep fronted first wave, when one radial is energized in the wind farm. However, differences were found in both simulation tools results compared with the measurements, in the more rounded fronted second waves.
