Abstract
Roebel cables with HTS strands exhibit reduced AC losses and possess large current carrying capacity. Even though works on several 2D and 3D numerical modelling and simulations are available, little efforts are made on computer-aided design (CAD) modelling, finite element analysis (FEA) and simulation of Roebel strands and cables. In this paper, finite element electromagnetic analysis and simulations of a 14-strand HTS Roebel cable is performed. The results obtained are then compared with another work which uses an H-formulation technique to model the problem. Although several numerical simulations have been carried out to optimise the HTS Roebel cable, no FEA work has yet been conducted on the complete 3D structure of Roebel cable. This work can therefore be considered as an initiator of the 3D finite element electromagnetic analysis of HTS Roebel cables.
