The invention relates to an intelligent substation secondary virtual loop visualization method based on graphic configuration plug-ins, and belongs to the technical field of electric power system intelligent substation automation. The method comprises: through establishing an intelligent substation secondary virtual loop database model, importing secondary virtual loop incidence relation of a substation configuration description (SCD) model to a monitoring background configuration database, in a configuration tool, dragging corresponding business tree nodes into a configuration screen, to generate a virtual loop configuration graph in a corresponding hierarchy, and associating corresponding node business data, and according to the state of the loop, displaying the secondary virtual loop of the intelligent substation on a monitoring background screen. Through using pictures based on graphic configuration plug-ins, and a convenient business association method, multi-stage total state of the secondary virtual loop of the intelligent substation is displayed on a monitoring background real-time screen in real time, so as to ensure stable operation of a substation system.
