Performance analysis of flux-lock type SFCL influenced by characteristics of two coils

open access: yes, 2014
The fault current limiting performance of flux-lock type High Temperature Superconducting Fault Current Limiter (HT-SFCL) is largely determined by the characteristic of the two coils on the iron core, including the direction of the windings, number of ...

Feasible protection strategy for HVDC system by means of SFCL and passive resonance DC breaker

open access: yesThe Journal of Engineering, 2019
The key obstacle in implementing high-voltage direct current (HVDC) grid, which is considered as the future of power grid, is the absence of effective DC circuit breaker (DCCB). At present, HVDC grid could be based on half-bridge (HB) or full-bridge (FB)

ENHANCEMENT OF VOLTAGE SAG & TRANSIENT STABILITY USING RESISTIVE TYPE SFCL FOR FAULT APPEARANCES [PDF]

open access: yes, 2016
The proposed structure prevents voltage sag and phase-angle jump of the substation PCC after fault occurrence. This paper proposes a new SFCL structure with a comparison of parallel-LC-resonance type fault current limiter (FCL) that uses a resistor in ...
