Automatic identification method of information model based on IEC61850 logical nodes

The invention relates to an automatic identification method of information model based on IEC61850 logical nodes, and belongs to the comprehensive field of computer software technology and electric power system automation technology. By establishing a IEC61850 logical node mapping rule matrix, data objects of a data set are mapped to the defined processing scheme, and a public data class rule base is allocated; after a CDC rule base is used to generate an initial system model object, a data object index is used to query a logic node rule matrix, and then the private property of a system model object is set according to the matched processing scheme to complete the automatic identification of the information model. According to the automatic identification method provided by the invention, the manual intervention situation in an intelligent substation database configuration is reduced, and the problems of high configuration workload, low efficiency, and easiness in errors are solved, so that the working efficiency is obviously improved.
