Multiterminal DC (MTDC) distribution systems have a sharply rising speed and high fault current. Superconductor fault current limiter (SFCL) can effectively mitigate this issue. While several topologies of SFCLs have been proposed, no comparative analysis of their current limiting performance in combination with dc circuit breakers (DCCBs) in MTDC distribution systems has been conducted. In this article, three types of SFCLs are modeled, including the resistive SFCL (R-SFCL), saturated iron core SFCL, and hybrid SFCL for a four-terminal +/- 10 kV dc distribution system, and the fault current i...
