Abstract :
A computational technique is proposed for the analysis and design optimization of inductive-type superconducting fault current limiters (SFCL) with variable impedance for power systems application. The technique is applicable for a wide range of magnet systems. The paper is focused on the analysis of electromagnetic transients. A methodological example of a model SFCL is presented. Numerical experiments are described to study nonlinear effects at saturated and unsaturated states. Results demonstrate that the nonlinear magnetic behavior of the SFCL components affects noticeably the accuracy of predictions.
