Abstract： In response to the problem that the proportion of power electronic devices in the new power system is increasing， leadingtointensifiednonlinearresponsesandasignificantincreaseinharmoniccomponentsofsingle-phasegrounding fault curents，and traditional arcsuppression methods are dificult toefectively suppress thearc，this paper proposed anarc suppression methodbasedon fractional order modelpredictivecontrol（FOMPC）.Firstly，thetraditionalinductors in the double-linked H-bridgewerereplacedwithfractional-orderinductorsofdiferentorders.Secondly，thecorrespondingorder modelpredictivecontrol method was adopted to compensate for thefault residualcurrnt based onthe principleof minimizing thecurent tracking eror，therebyachieving effectivearcsuppression.Finally，the performanceof themethod wasverified through hardware-in-the-loop experiments.Theresults show that using the appropriate orderFOMPCforarc suppreion has superior performance inresponse speedandarc suppressionefect.The integrationoffractionalcalculus theory withactivearc suppressioninvertersanditscontrolcanimprove theresponse speedandreduce thefultcurent，providingareferenceforfault suppression in power electronicized power grids.
