Investigation of AC Loss in HTS Cross-Conductor Cables for Electrical Power Transmission

Abstract

This paper presents the alternating current (AC) loss analysis on high-temperature superconductor (HTS) Cross-Conductor (CroCo) cables, in order to evaluate whether they could be utilized for electrical power transmission. The modeling of HTS CroCo cables was based on a cable assembled at the Karlsruhe Institute of Technology (KIT) and the AC loss calculation was based on the H-formulation model implemented in the finite-element method (FEM) software package COMSOL Multiphysics. The AC loss calculations have been carried out for isolated single-phase CroCo cable and three-phase CroCo cables. The AC loss angular dependence of a particular phase of CroCo cables during three phase operation has been studied. The current distributions of individual tapes within CroCo cables have been investigated.
