Fuzzy inference based topological real-time specification and correction method for CIM (common information model)

The invention relates to a fuzzy inference based topological real-time specification and correction method for a CIM (common information model). The method includes the steps of firstly, acquiring data of an SCADA (supervisory control and data acquisition) system and an EMS (energy management system) in real time; secondly, establishing a credible set U and a non-credible set V of key equipment nodes according to the data acquired in real time; thirdly, calculating a membership degree value of each key equipment node; fourthly, correcting the membership degree value of each key equipment node; fifthly, reorganizing the CIM according to the credible set U and the non-credible set V. The fuzzy inference based topological real-time specification and correction method for the CIM has the advantages that the problem of deviation of the corresponding relation between a power grid topology CIM structure and real-time data can be solved and errors after power grid topologies processed in real time are merged are eliminated; fuzzy inference can be well performed according to the relation among all kinds of data so as to obtain a basic data source closer to a true power grid, and making correct judgment and decision on the power grid is facilitated.
