The invention provides a multi-adaptive CIME power grid model sharing method. The method comprises the steps of S1, mapping CIME power grid model files into relation model files; S2, making table names in the relation model files and class names in CIM/RDFS model files correspond, and making the domains in the relation model files and the attributes in the CIM/RDFS model files correspond to form sharing model configuration files; S3, defining the sharing mode used when a CIME model performs model sharing in a current system to form model sharing scene files; S4, constructing a CIM/RDFS-based power grid model and performing correlation according to the correlation rules of various kinds of objects of the CIM-RDFS-based power grid model. The method maintains the high efficiency of CIM/E model files in a model interaction process and combines the characteristics of convenient use, flexible model extension and reusability in CIM/RDF Schema; the multi-adaptive model sharing method is provided for engineering application.
