Abstract:

The realization of fast and effective fault current limitation is one of the key technologies for the control and protection in DC systems. The DC superconducting fault current limiter (SFCL) developed from superconducting characteristics has ideal current-limiting performance, which has been widely studied and continuously developed in recent years. The main types and operation principles of the existing high-temperature SFCL are summarized based on the current-limiting effect presented by the superconducting module. The influence of superconducting materials on the current-limiting performance and applicability of SFCL is described. The connection scheme of SFCL in DC systems is illustrated. Also, based on the cooperative relationship among DC SFCL, converters and DC circuit breakers, the performance requirements of DC SFCL applied in DC systems are refined. The development pattern of DC SFCL is concluded to indicate the future application trends of DC SFCL.
