[0021] The smart substation GOOSE virtual secondary circuit graphical method is based on the SCD file, and the GOOSE information with a large number and complex connection relationship in the file is displayed in a graphic way according to the concept of the traditional relay protection secondary circuit. GOOSE's input and output information establishes a virtual connection diagram, which has enough optical interfaces to access the GOOSE information of the A and B networks of the high, medium and low voltage levels of the substation at one time, and the A of each voltage level , The physical isolation of the GOOSE optical interface between the B networks does not affect each other. The SCD file is mainly composed of Header, Substation, Communication, IED and DataTypeTemplates. Each node is organized in a tree-like hierarchical structure, such as figure 1 As shown, the first part Header contains SCD file identification information, file version information, configuration tool in...
