(TU Delft DC systems, Energy conversion & Storage) Contributor Ferreira, Jan Abraham (promotor) Polinder, H. (copromotor) Abrahamsen, Asger Bech (copromotor) Degree granting institution Delft University of Technology Date 2017-06-20 Abstract In recent years, superconducting synchronous generators (SCSGs) have been proposed as an alternative to permanent magnet synchronous generators (PMSGs). They are expected to reduce the top head mass and the nacelle size for such large wind turbines. In 2012, the INNWIND.EU project initiated this research to investigate SCSGs for 10-20MWdirect-drive offshore wind turbines. However, the feasibility of SCSGs was limited by a few critical issues, such as high costs, AC losses in the superconducting winding and excessive short circuit torque. Furthermore, SCSG designs proposed in the literature were various but all less competitive than PMSGs.
