Influence of Shunt Branch on the Current Limiting and Recovery Performance of Variable Resistance SFCL

IEEE Access
With the continuous development of power grid, the high short-circuit threatens the stability of the power system. The short-circuit exceeds the disconnection capacity of the circuit breaker and has a negative impact on the integrity and stability of the

Study of Superconducting Fault Current Limiter Functionality in the Presence of Long-Duration Short Circuits

Energies
In this paper, superconducting fault current limiter (SFCL) operation in the presence of a long-duration fault is presented. The SFCL device utilizes second-generation high-temperature superconducting (2G HTS) tapes, which exhibit zero resistance under ...

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

The 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)
