This　paper　proposes　a　simulated　model　of　micro　grid　control　system　based　on　IEC61850　standardized　information　network　In　the　model　process　level,　a　micro　grid　consisting　of　2　DGs　and　4　feeders　is　simulated　by　a　C　program　generated　from　a　Simulink　Coder.　In　the　model　bay　level　and　station　level,　IEC61850　communication　infrastructure　is　simulated　to　include　intelligent　electronic　devices　server　and　client　programs　for　supervisory　control　and　data　acquisition.　Fault　line　selection　algorithm　and　fault　isolation　with　IEC61850　is　implemented　in　this　model.　The　proposed　model　and　tools　is　suitable　for　researching　the　application　of　IEC61850　in　micro-grid　systems　and　for　verifying　the　micro-grid　control　and　protection　algorithm.
