Application of Superconducting Fault Current Limiter (SFCL) for HVDC system with Mechanical Circuit Breaker

SF6passive resonance DC circuit breaker combined with a superconducting fault current limiter

“…The combination of an R‐SFCL and mechanical‐type DCCBs would provide an effective method to isolate a short circuit in DC systems due to the high interruption properties and the low on‐state loss of mechanical‐type DCCBs. The application and the protection strategy of R‐SFCL with mechanical type DCCB are analysed in the HVDC system [42, 43]. Lee et al [44] suggest a feasible fault protection strategy based on SFCL and passive resonance DCCB that could be applied effectively to half‐bridge DC systems.…”
