For smart substations, the available visualization tools cannot display all the information of the secondary circuit, which hinders the field work of operation and maintenance personnel.To solve the problem, this paper fully analyzes the virtual connections between protection devices and intelligent electronic devices (IEDs) in smart substation, and develops a whole-station visualization method of secondary circuit in smart substation, drawing on hybrid topology.The visualization process was introduced in details, including key steps like the judgment of core IEDs, generation of local diagrams, and the formulation of the whole-station secondary circuit diagram.The proposed method was further explained with an example.The example analysis shows that our method could visually display the connections and data transmission between secondary devices in smart substation, allowing relevant personnel to quickly familiarize with the network structure and virtual connections of secondary devices throughout the substation.The research results help to reduce omissions and incorrectness in operations, and push up the operational efficiency in smart substations.
