Development of superconductors for a 70 MW class superconducting generator

Since 1988 a project has been underway in Japan in which superconducting generators for utility applications are being developed. The aim of the project is the development of a 200-MW-class superconducting pilot generator. During development work, of 70-MW-class superconducting, model generators are being run in order to clarify the problems in manufacturing and operating the pilot generator. The design of the model generator and the development of the components, especially the superconductors for the generator are discussed. Details of the development of the superconductor installed in the rotor are described
