Modelling of Resistive Type Superconducting Fault Current Limiter for HVDC Grids

Energies, 2022
The protection of high voltage direct current (HVDC) grids is a challenge considering that the protection system must detect, locate, and interrupt large fault currents in a few milliseconds. Resistive type superconducting fault current limiters (R-SFCL)

Design and application of superconducting fault current limiter in a multiterminal HVDC system [PDF]

, 2017
Voltage source converter based HVdc (VSC-HVdc) systems are prone to high short-circuit current during transmission line faults. The situation for multiterminal HVdc (MTDC) systems is worse.
