Intelligent Information System Modeling Analysis for Substation Based on IEC61850

From the several basic aspects of transformer substation function,such as decomposition,abstract,modularization and package,the paper introduces communication series standard IEC 61850 as well as its application in intelligent transformer substation information system,establishes the information model of electronic equipment in the intelligent transformer substation based on the IEC 61850 standard,expounds the models and internal connection among the models in depth,and discusses modeling process under the IEC 61850 standard,which provides a reference for information system construction of intelligent transformer substation.
