Abstract: Abstract:A method to import and export the virtual terminal information used in commissioning and reconstruction of smart substation was introduced. The first step is to write the virtual terminal information into a fixedfield format file. Sequently, the virtual terminal information can be imported by oneclicked operation. Then the virtual terminal configuration of whole substation is accomplished. After this, the virtual terminal information file can be exported by oneclicked operation. Using the file, it is convenient to rewrite the virtual terminal connection relation in smart substation reconstruction and to backup the virtual terminal connection relation. The engineering practice shows that using the function, the workload of virtual terminal configuration of a smart substation was reduced considerably.
