Abstract

In this study the proposed series-parallel resonance-type fault current limiter (SPRFCL) is compared with other parallel resonance-type FCLs (fault current limiter) recommended in the literature for symmetrical and asymmetrical faults to reveal its applicability. The first aim of resonance circuits is to effectively limit the increasing fault current at an allowable value after a fault happened. As a second goal, maintaining the PCC (point of common coupling) voltage at its nominal value during the fault has been handled to carry out the grid code requirements and to protect the sensitive loads connected to this point. Among all FCLs, SPRFCL has been the most efficacious limiter that can successfully suppress fault currents in different fault types and preserve the level of PCC voltage at the duration of the fault. Also, it has an advantageous design in terms of occurred instantaneous power losses on it and the maximum voltage and current levels of semiconductor switches.
