Superconducting fault current limiters (SFCLs) can be used to limit currents in both meshed DC and AC grids by transitioning from superconducting resistive state, the presence of high currents. While device is theoretically a great way protect grids, inherent inhomogeneity critical along superconductor length lead localized heating, called hotspots, ultimately destruction SFCL device. At EPFL u...

This paper shows a solution for controlling shortcircuit currents of a power electronic based Fault Current Limiter (FCL). A model for control design of three-phase short-circuit currents will be presented. A way of limiting the maximum aperiodic short-circuit current is derived with special regards to the stability of the entire system. Control designs of singleand two-phase shortcircuit curre...

The resistive superconducting fault current limiter is well known for its simple structure and outstanding current-limiting effect, it broadly applied in power grid systems. second-generation high-temperature superconductor (HTS) tape, of higher structural strength greater room-temperature resistance, suited application limiters. quenching caused by overcurrent the HTS tape a complexed coupling...
