Taking the typical intelligent GIS monitoring of IED as the example and according to IEC 61850 standard

this writer establishes a dispended logic node for each function through illustration of the functions of monitoring IED

then select and instantiates the category of compatible data possessed by every logic node;the writer have presented the principle and step to instantiate the modeling

analyzed and discussed the key issues such as the modeling features

the name of the instantiating the logic node

classification of the target data. The model document for intelligent GIS monitoring of IED has been developed in this report

and accepted the correctness verification.
