Abstract

This paper describes the results of investigative studies performed for various design topologies of a direct drive HTS wind turbine generator. The investigation covers electrical, mechanical and thermal design with special considerations for design optimization for cost reduction and practical manufacturability for commercial applications. Detailed modeling and analyses are performed by taking into account the characteristic properties of the HTS and non-HTS materials. The investigations also use improved YBCO second generation (2G) HTS wire under development in a research program sponsored by the U.S. Department of Energy.
