Wind power generation facilities have been installed across the world as a renewable energy source and the power capacity of a single wind turbine generator has been increasing. It is expected that superconducting technologies can be applied to the class of generators that is over 10 MW. This article reports on the fundamental structures and system configurations of large-scale wind turbine generators, and the design issues of large superconducting machines, while paying attention to the reduction of the superconducting wire length, and the generator size and weight. Some design results for 10 MW wind turbine generators are shown; a conventional permanent-magnet type, superconducting field coil types with salient poles and non-salient poles, and a fully superconducting type.
