Checking method and device for primary wiring diagram of intelligent power grid plant station

The invention discloses a checking method and device for a primary wiring diagram of an intelligent power grid plant station, and the checking method and device are applied to a dispatching master station, and the method specifically comprises the following steps: obtaining a first plant station primary wiring diagram based on a substation SCD model; collecting a primary wiring diagram of a second plant station; respectively extracting topology detection data of the first plant station primary wiring diagram and the second plant station primary wiring diagram, and correspondingly forming a target undirected graph and a query undirected graph; obtaining a mapping relation between the query undirected graph and the target undirected graph through a matching algorithm; based on the obtained mapping relation, checking of the primary wiring diagram of the intelligent power grid plant station is completed. Through plug-and-play and automatic checking of the wiring diagram matched with the diagram, the complexity of
