In　order　to　solve　the　defect　that　the　resistance　value　of　the　superconducting　quench　state　cannot　be　adjusted　when　a　fault　occurs.　This　paper　proposes　a　hybrid　superconducting　current　limiter　(H-SFCL)　with　the　bridge　circuit　topology　based　on　resistance　superconducting　current　limiter　(SFCL)　and　insulated　gate　bipolar　transistors　(IGBT)　control　current　limiting　resistors.　The　influence　of　the　access　to　the　hybrid　superconducting　current　limiter　on　the　fault　characteristics　of　the　DC　distribution　system　is　analyzed.　Then　the　improved　Hausdorff　distance　protection　scheme　is　proposed.　Compared　with　the　original　protection　principle,　it　not　only　has　absolute　selectivity　in　the　presence　of　large　transition　resistance,　but　also　has　high　sensitivity.　The　proposed　protection　scheme　is　simulated　in　MATLAB/Simulink　software.　And　the　simulation　results　show　that　the　protection　improvement　scheme　of　DC　distribution　system　with　hybrid　superconducting　current　limiter　can　quickly　and　accurately　remove　the　line　fault.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
