Design and Characteristic Analysis of 10 MW Class Superconducting Wind Turbine Generators with Different Types of Stator and Rotor Configurations

Wind power generation facilities have been installed in the world. Recently offshore wind energy attracts greater attention, and development of wind turbine generators of higher power rating becomes more important. Superconducting technologies is expected to be applied to over 10 MW class generators. We have studied 10 MW class large wind turbine generators using superconducting technologies. The paper presents fundamental structures of large-scale wind turbine generators, paying attention to the reduction of superconducting wire length, and generator size and weight. Some design results of 10 MW wind turbine generators are shown and compared.
