15兆瓦级海上漂浮式风力发电机直驱全超导发电机概念设计。采用场内临界电流大的高性能EuBa2Cu3Oy（EuBCO）超导线，可以减少发电机的导线长度。设计研究显示出良好的电磁特性：96.5% 的高效率和 0.4 p.u. 的低同步电抗。超导发电机（包括支撑结构）的总重量假设为~98吨，比部分超导发电机和传统发电机轻得多。此外，我们的超导发电机由于采用了高性能EuBCO导线并通过独特的外壳结构减少了励磁绕组长度，满足了成本要求。综上所述，全超导发电机具有很大的优势，特别是对于数十兆瓦的风力发电机系统。
15 MW-class Direct-drive fully-superconducting generators for offshore floating wind turbine generators were conceptually designed. High-performance EuBa2Cu3Oy (EuBCO) superconducting wires with a large in-field critical current were employed, which can reduce the wire length of the generators. The design study showed good electromagnetic properties: high efficiency of 96.5%, and a low synchronous reactance of 0.4 p.u. The total weight of the superconducting generators including support structures was assumed as ~98 tons, which is much lighter than partially-superconducting generators and conventional generators. Furthermore, our superconducting generator satisfied the cost requirement due to employing high-performance EuBCO wires and reducing field winding length by a unique casing structure. In conclusion, the fully-superconducting generators have a great advantage, especially for a tens-MW wind turbine system.
