The Application Of Superconductors In The Field Windings Of Large Synchronous Machines

In this paper, past experience and present knowledge are used to speculate on the applicability of superconductors in the field windings of large synchronous machines. The prospects look quite attractive for 3600 r/min and 1800 r/min turbine generators in the range of ratings from 1000-10,000 MVA. The prospects are also bright for synchronous condensers and peaking generators provided refrigeration can be supplied in an economical manner.
