Power grid equipment model automatic fusion maintenance method, device, equipment and medium

The invention provides an automatic fusion maintenance method and device for a power grid equipment model, equipment and a medium. The method comprises the steps of determining mapping of a master station and a plant station; setting a boundary cutting definition of the plant station model; designing a service interface for interaction of the master station and substation integrated system model; the master station realizes seamless importing of the substation model according to the boundary of the substation model by combining a model welding method; the master station realizes automatic importing of a point table according to model matching mapping; under the condition that the model data and the point table data are consistent, automatic information transmission, data checking and equipment transmission acceptance inspection of monitoring points are carried out; and generating a topological relation, and carrying out verification analysis on the topological relation. According to the method, mapping betwee
