In　this　paper,　a　hybrid　flexible　current　limiter　is　proposed　to　solve　the　problem　of　short　circuit　between　positive　pole　and　negative　pole　in　DC　distribution　network.　The　current　limiter　consists　of　superconducting　resistance　and　self-excited　current　limiter.　In　normal　operating　condition,　the　current　limiter　and　self-excited　current　limiter　are　bypassed　by　the　bridge　circuit,　so　that　the　current　limiter　has　no　impact　on　DC　distribution　network.　When　a　short-circuit　fault　happens　between　positive　pole　and　negative　pole,　the　bypass　function　of　bridge　circuit　is　failed.　With　the　help　of　the　current　limiter,　the　fault　current　and　the　voltage　drop　of　interelectrode　capacitance　can　be　quickly　suppressed　by　superconducting　resistance.　For　fully　remove　the　negative　effect　of　fault　on　interelectrode　capacitance,　through　offering　a　controlled　linearly　rising　current　to　an　inductor　in　the　set　time,　the　self-excited　current　limiter　can　provide　a　positive　clamping　voltage,　so　as　to　keep　the　interelectrode　capacitance＇s　voltage　in　its　rated　value.　Finally,　based　on　the　theoretical　derivation　and　simulation　results,　it　can　be　proved　that　the　major　problems　troubling　a　DC　distribution　network＇s　fault　ride-through　technologies　can　be　resolved　by　the　proposed　method.　©　2020　IEEE.
