The Transient and Steady-state Information Fusion Method for Single Phase Grounding Line Detection in Resonant Grounding System

Translated Abstract

The　feature　information　of　single　phase　grounding　fault　occurring　in　resonant　grounding　system　is　weak.The　existing　line　selection　based　on　single-fault-characteristic　is　difficult　to　achieve　reliable　line　detection.The　complementarity　of　three　single-fault-characteristic　such　as　energy　ratio　of　zero-sequence　current,zero-sequence　active　power　ratio　and　variation　ratio　of　negative-sequence　current　was　comprehensively　considered.A　new　method　using　multiple　neural　networks　to　fuse　transient　and　steady-state　characteristics　was　proposed　for　fault　line　detection　in　the　resonant　grounding　system.Different　integration　programs　have　been　taken　respectively　to　distinguish　the　differences　between　stable　and　unstable　ground　fault.Lots　of　simulation　results　verify　that　the　proposed　method　for　fault　line　detection　is　less　affected　by　grounding　location,grounding　time　and　grounding　resistance.With　good　robustness,it　can　be　applied　to　detect　fault　line　under　all　kinds　of　single　phase　grounding　conditions.
