1MVA Superconducting Generator Design

1MVA 급 초전도발전기 설계

Generally superconducting generators(S. G.'s) will be classified into 2 types according to their field coil shape. The first one is race-trace type and the other is saddle type. Race-track type S.G.'s have almost the same structure with conventional salient pole generators which are being used as largely small scale machines with more than 4 poles. On the other hand saddle type S.G.'s correspond to conventional cylindrical generators with 2 poles used for large turbines in power plants. In this paper 1MVA S.G. with saddle type field coil is electromagnetically designed and based on the research results from development of 30kVA S.G. with race-track type field oils in our group. other parts such as cooling systems and power leads are presented.
