基于故障点电压的单相自适应重合闸判据Keywords: adaptive,single-pole,autoreclosure,fault,location,permanent,fault,transient,fault,fault,point,voltage Abstract: Anewadaptivesingle-poleautoreclosuretechniquebasedonthemagnitudeoffaultpointvoltageispresented.Afterfaultphasetripping，thefaultpointvoltageoftransientfaultsisessentiallydifferentfromthatofpermanentfaults，sothemagnitudeoffaultpointvoltageisusedtodistinguishfaultnature.Faultpointvoltagecanbecalculatedthroughuniformtransmissionlineequation.Consideringthatfaultpointvoltagechangeswithfaultlocationandtransitionresistance，aconceptofreal-timeactionvoltagesettingisputforward.Thetechniquesolvestheproblemthatcriterionsbasedonterminalvoltagecouldbeeasilyaffectedbyinductivecouplingvoltageandtransitionresistance.Simulationresultsshowthatthemethodisreliable.
