In　recent　years,　to　build　smart　grid　becomes　a　new　focus,　and　how　to　fully　collect　and　make　effective　use　of　the　information　of　the　intelligent　secondary　device　get　abroad　attention.　This　paper　presents　a　grid　fault　information　intelligent　analysis　and　processing　system.　It　is　a　platform　of　fault　information　intelligent　processing,　used　for　an　incorporate　control　center　system　of　province　and　district　level.　It　works　in　two　parts,　substation　and　control　center.　In　the　substation,　a　slave　system　device　gather　the　information　of　relays　and　deliver　it　to　the　master　system　in　the　control　center　through　Ethernet,　and　a　recorder　proxy　device　gather　the　information　of　recorders　and　deliver　it　to　the　master　system　through　another　Ethernet　channel.　The　software　in　the　control　center　has　a　layered　and　distributed　structure,　and　import　the　information　of　relays　and　recorders　with　two　isolated　server　in　the　data　layer.　The　application　layer　of　the　software　system　can　gather　the　information　to　a　integrated　report　of　a　grid　disturbance　or　fault　with　special　process,　include　of　using　the　fault　index,fault　time,　etc.　This　method　is　effective　of　reduce　the　requirement　of　the　hardware　resource　of　the　slave　system,　and　can　decrease　the　chance　of　Ethernet　block.　It　can　support　the　decision　of　the　dispatcher　and　fleetly　deal　the　gird　fault.　This　system　has　been　used　in　the　control　center　of　Taizhou　district　in　Zhejiang　province,　and　remarkably　improves　the　level　of　management.　The　system　is　programmed　to　integrate　with　information　of　other　systems,　such　as　SCADA　and　EMS,　and　will　get　whole　view　of　the　grid　information　to　give　stronger　support　of　building　a　smart　grid.　©　2010　Chinese　Soc　for　Elec　Eng.
