Abstract：

Aiming　at　the　problem　that　the　existing　single-phase-to-ground　fault　flexible　compensation　device　has　low　compensation　accuracy,　long　response　time,　and　needs　DC　side　power　supply,　a　flexible　compensation　device　based　on　double-loop　passivity-based　control　is　proposed.　Firstly,　the　topology　and　working　principle　of　the　device　are　analyzed.　And　a　compensation　current　distribution　method　of　the　bridge　arm　is　proposed.　Secondly,　a　double-loop　passivity-based　controller　is　designed.　Finally,　the　proposed　method　is　verified　by　MATLAB/Simulink　software　and　10　kV　physical　simulation　system　of　distribution　network.　The　comparisons　between　double-loop　passivity-based　control,　passivity-based　control,　and　proportional　integration　control　is　discussed.　The　result　shows　that　the　proposed　method　can　accurately　and　rapidly　compensate　the　fault　current.　©　2024
