In this paper, two types of conceptual structures of 10 MW fully superconducting offshore wind turbine generators (FSWTG) with an efficient electrical design method are presented. Four types of generator models, Gen. A - D, are compared according to different armature winding structures, and it's found that Gen. A is the preferable one. Optimization of the main generator parameters reveals that 36 poles with a pole pitch of 474 mm and electrical load of 6.0 kA/cm yields the best performance. The different design parameters of FSWTGs are compared to partially superconducting wind turbine generators (PWTG) with HTS field windings and copper armature windings and traditional wind turbine generators (WTG). Results show that FSWTGs are smaller in size, weigh 0.7 and 0.4 times less and are more efficient by 1.9-2.1% and 2.9-3.1% than PWTGs and WTGs, respectively. Lastly, the AC losses generated in the superconducting armature windings of the four types of FSWTGs are calculated and discussed.

本文提出了两种具有有效电气设计方法的10 MW全超导海上风力发电机（FSWTG）的概念结构。根据不同的电枢绕组结构比较了四种发电机模型，即发电机A-D，发现发电机A是最好的一种。对主要发电机参数的优化表明，36个极距为474 mm的极距和6.0 kA / cm的电负载可产生最佳性能。将FSWTG的不同设计参数与具有HTS场绕组和铜电枢绕组的部分超导风力发电机（PWTG）以及传统风力发电机（WTG）进行了比较。结果表明，FSWTG的尺寸较小，重量分别是PWTG和WTG的0.7和0.4倍，效率分别提高了1.9-2.1％和2.9-3.1％，分别。最后，计算并讨论了四种FSWTG的超导电枢绕组中产生的交流损耗。
