Design and analysis of a novel vernier reluctance fully superconducting synchronous generator with LTS windings for wind power generation

In this paper, a novel vernier reluctance fully superconducting synchronous generator (FSCSG) with low temperature superconductors (LTS) for wind power application is proposed. The feature of this superconducting generator is an external rotor structure, and both the superconducting armature windings and DC field windings are in the inner stationary stator. Thus, compared with the existing FSCSFGs, the cryostat and related refrigerate system of the proposed generator is greatly simplified. Besides, the results shows that the torque density is about 37% higher and the torque ripple is as low as 6.9% without any optimization and skewed.
