Abstract
The rapid development of renewable wind energy asks for new technology and the scheme of superconducting dc generators with superconducting dc transmission cables provides a possible and innovative solution to this trend. This paper designs a 10-MW superconducting dc generator with copper armature winding in the rotor. To find a suitable configuration of the armature winding, distributed winding, namely double-layer lap winding, and concentrated winding are analyzed and compared. The commutation principal of the two types of armature winding is briefly introduced by a simplified case. Electromagnetic performance, including torque, no-load voltage, and coil current, of the two types are calculated and compared based on the finite-element software. The reasons contributing to the performance difference are also elaborated.
