Automatic generating method of electric network station wiring diagram

The invention relates to an automatic generating method of an electric network station wiring diagram, which comprises the following steps of: a. establishing an interval model database, wherein the interval model database comprises all types of interval models in a station, each interval model is the most complete interval, each element equipment in the interval models is related to a check box, and the check box is used for numbering the related element equipment and supplying an operation interface for deleting the related element equipment; b. when the diagram is generated, selecting the interval model corresponding to the voltage grade of the station from the interval model database; and if the interval model needs to be modified, deleting the related and undesired element equipment by setting the check box, connecting the residual element equipment according to an interval wiring rule, and generating the corresponding electric network station wiring diagram. The invention realizes the function of automatically generating the diagram; the station wiring diagram can be automatically generated by a user through only simple selection and character input, the method saves time and labor, and the work efficiency is greatly improved.
