Research Of Low-voltage Equipment Management System Based On Graphic

Considering　the　fact　that　the　management　of　low-voltage　equipment　relatively　lags　behind　that　of　high-voltage　equiment　in　distribution　network　and　it　has　hindered　the　upgrading　of　the　whole　distribution　network　managemen,　the　management　system　of　low-voltage　equipment　based　on　graphic　is　put　forward　which　makes　the　best　use　of　GIS.　GIS　and　COM　technology　is　the　theory　foundation　of　the　system　and　the　low-voltage　line　map,　which　is　established　by　trans　area　using　MapX,　is　the　basis　of　the　whole　system.　All　the　management　functions　are　realized　on　the　line　map　and　if　there　is　enough　data　the　low-voltage　theretical　line　loss　can　be　calculated.　Project　design,　layout　design,　data　structure　design　and　the　difficulties　we　have　encountered　are　all　discussed　in　the　thesis.
