Superconductors for power applications: an executable and web application to learn about resistive fault current limiters

Abstract High-temperature superconductors (HTS) can be superconducting in liquid nitrogen (77 K) at atmospheric pressure, which holds immense promises for our future such as nuclear fusion, compact medical devices and efficient power applications. In a system, high short-circuit currents exceed the operational current by more than ten times, putting many parts of system risk. Superconducting fault limiters (SFCLs) limit prospective without disconnecting are thus becoming increasingly attractive grids. With growing interest modeling commercializing SFCL, question how to teach explain their operation students has arisen. order help visualize potential use benefits an we created executable web application using COMSOL Multiphysics. This allows investigate electro-thermal response resistive SFCL. The solves 1D model SFCL under AC conditions, evaluating important figures merit limited current, maximum temperature reached within tape. Finally, geometrical parameters well properties device modified. importance amount silver stabilizer necessary protect from over-heating occurring during investigated. addition, effects having sharp nonlinear transition normal state (intrinsic property superconductor) obtain limitation explored. users learn about real-life applications, prerequisite extensive or experimental setup. downloaded HTS website run on most commonly used operating systems.
