The invention discloses a method for graph-model information sharing of an intelligent substation and a dispatching master station.The method comprises the following steps that 1, an SCD file containing graphs and model information is created; 2, the dispatching master station guides the SCD file into a regulator control system and verifies the SCD file; 3, the verified SCD file is converted into a CIM/E file and a CIM/G file; 4, the converted CIM/E file is used for completing guiding of a model file through the model splitting and splicing technology; 5, the converted CIM/G file is guided into a man-machine system, graph-model relevance is verified, display is performed, and guiding of a graph file is completed.The static model file interaction process of the intelligent substation and the dispatching master station is simplified, graph, model and library integration of the intelligent power grid dispatching control system is achieved, and the feasible technological means is provided for intelligent power grid source end maintenance and global sharing.
