Current　single-ended　fault　location　methods　for　single-phase　ground　faults　in　distribution　networks　are　facing　challenges　such　as　difficulty　in　identifying　reflected　wavefronts,　inaccurate　judgment　of　wavefront　reflection　positions,　and　limited　noise　immunity,　which　reduce　their　feasibility　for　engineering　applications.　This　article　proposes　an　efficient　single-ended　traveling　wave　location　scheme　aimed　at　enhancing　the　accuracy　and　reliability　of　fault　location.　First,　the　improved　Pettitt　test　is　employed　to　accurately　determine　the　arrival　time　of　the　fault　wavefront,　which　avoids　errors　in　judgment　of　the　fault　occurrence　moment.　Subsequently,　the　Pearson　correlation　coefficient　is　utilized　to　identify　the　initial　wavefront　and　the　wavefronts　reflected　from　the　fault　point,　reducing　interference　caused　by　other　reflected　wavefronts.　To　accurately　calibrate　the　wavefront　arrival　time,　the　Hough　transform　is　introduced　to　determine　the　wavefront　position.　In　addition,　this　article　discusses　optimizing　the　arrangement　of　traveling　wave　location　devices　in　the　distribution　network　to　improve　location　accuracy　and　reduce　costs.　Compared　to　existing　methods,　the　proposed　scheme　directly　analyzes　the　original　waveform,　achieving　more　accurate　wavefront　identification　and　better　noise　immunity.　The　effectiveness　of　the　method　is　validated　through　software　simulations　and　physical　experiments,　demonstrating　that　the　fault　location　error　can　be　controlled　within　5%,　even　under　arc　ground　faults　or　noise　interference.　©　1963-2012　IEEE.
