Harmonic modelling of offshore wind farms

The combination of extensive cable networks and wind turbine converters has been identified as a potential cause of resonances. A modelling approach for a doubly fed induction generator and a full power converter fed generator for harmonic penetration studies is developed and discussed. An example offshore wind farm is then studied in the simulation package IPSA using the detailed wind turbine generator model in order to assess the harmonics at the onshore connection point. The contribution from the various offshore wind farm components is considered. Harmonics from wind turbines under both high and low wind speeds are studied.
