Title:FaultDistanceAnalysisofDirect-supplyTractionPowerSystemwithReinforcedConductors
Abstract:
Thedirect-supplytractionpowersystemwithreinforcedconductorsiswidelyusedinrailwaytransportationduetoitsnumerousadvantagesincludingimprovedefficiencyandreducedelectricallosses.However,likeanycomplexpowerdistributionsystem,itissusceptibletofaultsthatcandisruptthesmoothoperationoftherailwaynetwork.Therefore,faultdistanceanalysisplaysacrucialroleinthemaintenanceandtroubleshootingofthedirect-supplytractionpowersystem.Thispaperaimstoprovideacomprehensiveanalysisoffaultdistanceidentificationtechniquesforthedirect-supplytractionpowersystemwithreinforcedconductors.
