Superconductors in large synchronous machines

Research was organized around three major activities: (1) two complete superconducting alternators were designed, constructed, tested and evaluated; (2) design studies of full-scale turbine generators were iterated three times resulting in the design of the 3MVA machine and the use of experimental results from the 3-MVA machine in the optimization of the design of full-scale turbine generators; and (3) development of concepts and analytic methods for the design of superconducting machines has included overall electrical analysis of the machine based on two-dimensional magnetic field models, machine dynamic performance including fault transients, cryogenic design and optimization, and analysis of new machine concepts.
