Design guideline of flux-lock type HTS fault current limiter for power system application [PDF]

open access: yes, 2001
We have proposed a “Flux-Lock” type high T, superconducting (HTS) fault current limiter (FCL) composed of the flux-lock reactor with HTS element and the magnetic field coil circuit, In this FCL, the initial limiting current level can be arranged by ...

Critical Current Degradation in HTS Tapes for Superconducting Fault Current Limiter under Repeated Overcurrent

open access: yesApplied Sciences, 2023
Superconducting fault current limiters (SFCL) can be an alternative to conventional devices limiting short-circuit currents in power systems. SFCL use high-temperature superconducting tapes of the second generation (HTS 2G) in SFCL, which, after reaching

Superconducting Fault Current Limiters for HVDC Systems

open access: yesEnergy Procedia, 2015
AbstractHigh-voltage direct current (HVDC) transmission systems using Voltage-Source Converters (VSC) are widely recognized as offering significant potential for long distance high power delivery, particularly for offshore wind farm connections. One of the barriers for the development of multi-terminal HVDC systems is the lack of technologies which ...

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

open access: yes, 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.

Superconducting fault current limiter application in a power-dense marine electrical system

open access: yes, 2011
Power-dense, low-voltage marine electrical systems have the potential for extremely high fault currents. Superconducting fault current limiters (SFCLs) have been of interest for many years and offer an effective method for reducing fault currents.
