A Data-driven Approach to Automatic Generation and Autonomous Verification of Virtual Circuits in Intelligent Substation

A data-driven intelligent substation virtual loop automatic generation and independent verification method is proposed. The virtual connection information of the historical substation configuration description (CD) file is rapidly extracted by using the document object model (DOM) method，and the historical SCD database is constructed. The precise matching of the information of the intelligent electronic (IED) to be designed and the historical IED information is realized，and then the automatic generation scheme of the virtual connection is proposed. In view of the problems ofconnection and missed connection in practical application，the standard template library is constructed to verify the virtual connection generated automatically，and the visualization technology is used to realize the alarm，reminding the to add and modify the virtual connection. The correctness of the proposed method is verified based on an actual intelligent substation case.
