The Influence of the Geometrical Properties of Bulk Superconductors on Limiting Fault Current in an Electrical Network

Advanced Electromagnetics, 2019
The behavior of the superconducting fault current limiters SFCL used in Electrical Network is largely determined by the geometry properties and the type of the bulk superconductors used. In this work we present a numerical analysis of the electromagnetic

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)
