Abstract. This work presents an evaluation methodology of electrical losses in the collector systems for different topologies considered nowadays in large offshore wind parks. Taking into account the current situation of the offshore collector systems, a summary about schemes employed in commissioned wind farms is presented. Electrical layout plays a key role in order to cut down Levelized Cost of Energy (LCoE). Based on the calculus of electrical losses, the authors select the optimum design of the array of the wind farm combined with the most adequate rated power offshore turbines. Power losses evaluation is verified with real cable data sheets and the methodology is applied to a real wind farm in construction.
Among the renewable energies, wind power has reached undoubtedly the greatest degree of maturity, although such maturity is based on the development of large-scale installations using larger machines every time. In recent years interest has grown in small wind generators, which allow access to this type of energy to small farms and to areas with difficult access. In this work, is performed the study of a permanent magnet synchronous generator (PMSG) using finite elements for such small applications. Various tests have been carried out to simulate no-load and short circuit conditions at different speeds in order to obtain data from these trials about their future behaviour.
