The　existing　flexible　suppression　methods　of　ground　faults　in　distribution　networks　are　greatly　affected　by　the　factors　like　the　measurement　accuracy　of　ground　parameters,　the　load　changes,　the　ground　fault　resistance　and　the　line　impedance　voltage　drop.　Therefore,　a　novel　fusion　suppression　for　ground　faults　in　distribution　networks　that　adapts　to　the　parameter　and　load　changes　is　proposed　in　this　paper.　Based　on　the　analysis　of　the　ground　fault　current　distribution　law,　a　fault　current　suppression　method　based　on　the　fault　phase　current　regulation　is　put　forward.　The　fault　point　current　is　suppressed　by　regulating　the　fault　phase　current　to　equal　the　fault　phase　load　current.　A　real-time　extraction　for　the　load　current　is　raised　to　adapt　to　the　load　changes　without　the　measurement　of　the　ground　parameters.　In　addition,　a　parallel　current-voltage　double　closed-loop　control　method　is　presented　according　to　the　application　scope　of　the　principles　of　current　and　voltage　suppression.　Both　the　fault　current　and　voltage　are　suppressed　to　accommodate　the　effects　of　the　ground　fault　resistance　and　line　impedance　voltage　drop.　Simulation　and　experimental　results　prove　the　effectiveness　and　advantages　of　the　proposed　method.　©　2023　Power　System　Technology　Press.　All　rights　reserved.
