METHOD AND APPARATUS FOR AUTOMATICALLY ASSOCIATING PRIMARY AND SECONDARY EQUIPMENT MODELS OF SMART SUBSTATION

Disclosed in the present invention are a method and apparatus for automatically associating primary and secondary equipment models of a smart substation: for a cross-interval secondary equipment model, configuring a specific interval prefix for each interval LN (logic node) in the model to implement interval LN grouping, and establishing interval association LN to provide a primary and secondary interval association interface; configuring an SCD file to implement the instantiation of each secondary equipment model, importing an SSD file into the SCD file, directly associating a single-interval secondary equipment CID file with a related primary interval in the SSD, and assigning each interval DO of the interval association LN in a cross-interval secondary equipment CID file to complete interval association; specifying a secondary equipment LN association relationship for a primary equipment object type; and, on the basis of the association relationship between the primary equipment object type and the secondary equipment LN, associating the primary equipment in each interval with the related secondary equipment LN in each single-interval and cross-interval secondary equipment model. The present invention implements the automatic association of primary and secondary equipment models of a smart substation.
