Virtual terminal connection imaging method based on security coding device (SCD) document

The invention relates to a virtual terminal connection imaging method based on a security coding device (SCD) document. The imaging method includes the following steps that a virtual terminal in the SCD document and a virtual terminal connection relation are pre-configured; imaging processing is conducted on the virtual terminal, and the SCD document is imported by using a virtual terminal connection imaging tool; imaging processing results are output and combined to obtain an IED complete virtual terminal drawing. By means of the imaging method, the important virtual terminal connection relation of an intelligent substation is displayed to users visually in a mode easy to read, verification of the intelligent substation is facilitated, and operation and maintaining requirements are met.
