Effect of Superconducting Fault Current Limiters on Successful Interruption of Circuit Breakers

The penetration of DG systems in distribution systems can result in the increase of the short circuit current level. The application of the fault current limiter (FCL) would not only decrease the stress on network devices, but also can offer a connection to improve the reliability of the power system. There are various types of FCLs, which are made of different superconducting materials and have different designs. There are several kinds of SFCLs, which can be classified in three types such as the resistive type, the inductive type and bridge type SFCL. In this paper, the transient recovery voltage (TRV) analysis, based on the electromagnetic transient program (EMTP), is used to investigate the behavior of the each three types SFCL installed in an electrical distribution grid. Simulation results show that the TRV can be damped in the presence of the resistive and bridge type SFCL during fault clearing period.
