Centralized feeder automation that has been widely applied in distribution networks needs to build an information model in compliance with IEC 61850 to satisfy the requirement of interconnection. The fault indicator related logical nodes in IEC 61850-90-6 technique report are described. On the basis of analyzing the working principle of centralized feeder automation

based on the new definition of current indicator logical node SCPI

voltage indicator logical node SVPI

fault indicator logical node SFPI

an information model of function realization of centralized feeder automation is studied to promote the application of IEC 61850 in distribution automation. This work is supported by Key Project of Smart Grid Technology and Equipment of National Key Research and Development Program of China(No. 2016YFB0900600).
