Abstract

Operations of superconducting fault current limiters proposed by our group are numerically simulated with a commercial software of finite element method. In order to reproduce experimental results with Y-based QMG bulk superconductors, the distributions of current and temperature inside the limiting devices are numerically solved at each time step for a half cycle of overcurrent. By using the obtained distributions, the analysis of internal stresses is also carried out to validate the structure of metal reinforcement. Furthermore, the current limiting behavior for voltage source is evaluated to simulate a realistic operation in actual power transmission lines
