Simulation for the Fault Current Limiting Operation of REBCO CORC Superconducting Cables With Different Core Materials

With high power density and low loss, CORC superconducting cables composed of RE $-$ Ba notation="LaTeX">$_{2}$ Cu notation="LaTeX">$_{3}$ O notation="LaTeX">$_{7-\delta }$ (REBCO)-coated conductors are great interest for transmission applications. They can also effectively be designed to serve as fault current limiters, thanks their sharp superconducting-to-normal transition. Coupled electromagnetic-thermal finite-element simulations implemented in COMSOL Multiphysics were developed validated against the published results limiting (FCL) performance two REBCO-coasted wound on either copper or stainless steel cores. For improved accuracy, temperature dependencies electrical thermal properties all component materials considered simulations. The performed cross sections every individual layer each REBCO tape deliver comprehensive understanding evolution distribution rise those layers. studies suggest approaches optimize cable design FCL applications by assessing role components. In article, possible computational errors, challenges, improvements discussed.
