Abstract

This paper analyzes the structure, the physical parameters and the working principle quantitatively of the single-phase DC-turned off High Temperature Superconducting Fault Current Limiter (SFCL) with Saturated Iron Core. On this basis, a dynamic system model is established and simulation to study the relationships among the various system electrical parameters. The simulation results and the actual waveforms collected from the sample machine were compared to verify the correctness of the model. And the simulation experiment shows that this kind of SFCL is available for current limitation.
