Short-circuit fault current-limiting characteristics of a resistive-type superconducting fault current limiter in DC grids

Superconductors Science and Technology, 2020
Resistive-type superconducting fault current limiters (R-SFCLs) can limit short-circuit fault current and help DC circuit breakers (DCCBs) to isolate short-circuit faults in medium voltage and high voltage DC (HVDC) systems.

Superconducting fault current limiter development

IEEE Transactions on Magnetics, 1991
The authors have developed and tested a 400-V 100-A-class fault current limiter wound with AC superconducting wire with ultrafine NbTi filaments. The limiter consists of noninductively wound superconducting trigger coils and a superconducting limiting coil which acts as a reactor.

A practical superconducting fault current limiter

IET Conference Publications, 2009
This paper discusses the increasing requirements for an effective means of controlling fault levels on electrical networks and describes the work by Rolls-Royce and partners to develop a practical superconducting fault current limiter. Practical superconducting fault current limiters require materials with a high tolerance to mechanical process ...

Development of Superconducting Fault Current Limiters

2006 International Conference on Power System Technology, 2006
Somewhere in a power utility system, a mishap may cause a short- circuit. The sudden reduction in the power grid's impedance will lead to a surge of current, termed fault current. Sometimes, fault currents can create disasters to power generators, distributors, and consumers.

Towards the superconducting fault current limiter

IEEE Transactions on Power Delivery, 1991
The advent of low-loss AC superconductor wires opens the way to a new current limiting technique: that of extremely fast transition from a superconducting state to a resistive state when the fault current exceeds the conductor's critical current. A 25 kV single-phase prototype is described which consists of a Nb Ti superconducting coil without iron ...

Modeling of the DC Inductive Superconducting Fault Current Limiter

IEEE transactions on applied superconductivity, 2020
DC fault current limiter is an important device for the dc system, because the action speed of the existing selective protection cannot match the dc fault developing speed.
