The application of superconducting technologies to electric power apparatuses is very important from the viewpoint of not only the promotion of energy and resources saving but also the improvement of power system stability. Super-GM was established in September, 1987 in order to proceed the research and development (R & D) on application of superconducting technologies to power apparatuses and Super-GM R & D project, which is sponsored by New Energy and Industrial Technology Development Organization (NEDO) under the Moonlight Project of Industrial Science and Technology, Ministry of International Trade and Industry, started from FY 1988 for a scheduled period of eight years. As to R & D on superconducting generator, the basic designs and analyses of 70MW class model machines and the research on element techniques concerning superconducting field winding, structural materials of multi-cylindrical rotor, warm damper, rotating cooling characteristics, helium transfer coupling and air gap armature winding of superconducting generator were conducted in FY 1988 and 1989, and many basic results were obtained. At present, R & D step is proceeding steadily from the research on element techniques to the examinations for manufacturing techniques using partial models such as field winding model, multi-cylindrical roter model, rotating cooling model, helium transfer coupling model and armature winding model for the manufactures and demonstration tests of 70MW class model machines. In this paper, the current situation of R & D on superconducting generator carried out by Super-GM is presented.
