The invention relates to a template for virtual terminal connection. A virtual terminal connection mode is stored on the basis of an all-station system of a transformer substation put into operation, and corresponding virtual terminal connection is automatically generated for the all-station system configuration file of the newly established transformer substation according to the template. A continuous updating maintenance equipment template library is formed by introducing the template, in which the connection mode is stored, templates and embodiments with the corresponding types are selected by a batched design method, SCD file production can be finished quickly and efficiently, and the efficiency can be improved on the automatic design aspect of the SCD file.
