Virtual loop configuration method and device, terminal equipment and storage medium

The invention discloses a virtual loop configuration method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining a system specification description SSD file of a transformer substation, and extracting a voltage level of a main wiring diagram of the transformer substation from the SSD file; interval data corresponding to the voltage level are extracted, a first interval and a second interval of the interval data are obtained, and the first interval and the second interval are different intervals; judging whether a connection relationship exists between the first interval and the second interval or not; if the connection relation exists between the first interval and the second interval, filling the connection relation into a preset interval relation table; a plurality of virtual terminals are displayed, a target virtual loop between the two virtual terminals is configured through the connection relations in the interval relation table, and the interval relation tab
