Method for automatically mapping digital substation interval wiring diagram

Manually drawing an interval wiring diagram is gradually unable to adapt to the development requirement of a digital substation. The invention relates to a method for automatic mapping a digital substation interval wiring diagram, which comprises the following steps of: firstly, reading and parsing an SCD (substation configuration description) file by an SCL (substation configuration description language) syntax parse module to acquire primary equipment information and connected relation; secondly, judging the mode of connection of the primary equipment and generating abstract interval information through the primary device function relation-chain algorithm module according to the primary equipment information and connected relation; subsequently, restoring the abstract interval information into an interval wiring diagram through an interval wiring diagram drawing module; and finally associating the interval wiring diagram and the database object by a database object associating module, and generating labels automatically for equipment in the interval wiring diagram through an equipment label labeling module according to the shape, direction and position of equipment. The method provided by the invention avoids the errors due to manual operation and provides a firm foundation for reliable operation of the digital substation.
