The invention discloses a substation model processing method for an integrated power dispatching and distribution system, which comprises steps of model analysis, model checking, model splicing, graph importing, graphic model library association and automatic preposition parameter maintenance. According to the substation model processing method for the integrated power dispatching and distribution system, after the boundary of the model is determined, an object in a CIM file is mapped to a specific device in a system database, the CIM model file provided by a PMS system and the model in the integrated power dispatching and distribution system are spliced to form a large power grid model.
