  • Superconducting coil system and methods of assembling the same
    Patent number: 9240681
    Abstract: A superconducting magnet apparatus is provided. The superconducting magnet apparatus includes a power source configured to generate a current; a first switch coupled in parallel to the power source; a second switch coupled in series to the power source; a coil coupled in parallel to the first switch and the second switch; and a passive quench protection device coupled to the coil and configured to by-pass the current around the coil and to decouple the coil from the power source when the coil experiences a quench.
    Type: Grant
    Filed: December 27, 2012
    Date of Patent: January 19, 2016
    Assignee: General Electric Company
    Inventors: Renuka Rajput-Ghoshal, James Humphrie Rochford, Probir Kumar Ghoshal
  • SUPERCONDUCTING POWER GENERATION SYSTEM AND ASSOCIATED METHOD FOR GENERATING POWER
    Publication number: 20150207365
    Abstract: A system includes a generator unit coupleable to a hydro turbine. The generator unit includes a casing having a first stationary support coupleable to a base disposed within water and a superconducting generator disposed within the casing. The superconducting generator includes an annular armature and an annular field winding including a plurality of superconducting magnets disposed coaxial with the annular armature and separated by a gap. One of the annular armature and the annular field winding is rotatable by the hydro turbine and other of the annular armature and the annular field winding is stationary.
