This　paper　presents　a　new　scheme　for　power　line　autoreclosure　technology,　the　integrated　adaptive　optimal　reclosure.　The　background　of　the　development　is　firstly　outlined　and　the　basic　principles　of　these　new　techniques　are　described.　These　include　the　adaptive　reclosure　and　the　optimal　reclosure　techniques.　The　new　scheme　proposed　is　based　on　the　latest　development　in　digital　substation,　in　which　the　proposed　new　techniques　are　implemented　into　a　specially　designed　integrated　reclosure　device,　which　is　responsible　for　the　protection　of　a　number　of　line　sections　associated　with　the　substation.　Studies　show　that　these　new　developments　offer　potential　for　significantly　improving　the　performance　of　the　power　system　protection　and　control.
