Development of 30 kVA class fully superconducting generator

A 4-pole 30 kVA class fully superconducting generator is being developed to investigate the characteristics of superconducting armature winding subject to the rotating magnetic field produced by the superconducting rotor and the behavior of a superconducting generator connected to an electric power utility grid. A static test of the armature winding has been performed by applying 50 Hz AC current. AC quench currents of the armature windings have reached 200 Arms after several quenches, which was well over the rated current. A static test of the field windings has also been performed to verify its rated performance. Detailed configurations and electrical test results of the generator are shown.>
