Method and apparatus for a superconducting direct current generator driven by a wind turbine

摘要

Disclosed is a direct current generator 22 including an annular armature 24 connectable to rotate with a rotating component of a wind turbine 10 and a stationary annular field winding 26 coaxial to the armature 24 and separated by a gap from the armature 24. The field winding 26 is configured to include superconducting coil magnets 68 and a support structure connectable to an upper region of a tower of the wind turbine 10. The direct current generator 22 further including a commutator assembly 90 configured to transfer DC current generated by the rotating armature 24 to a power conversion system 100.
