Problems solved by technology
IEC 61970 recommends adopting RDFS to standardize the vocabulary of XML documents, but for the Semantic Web, RDF / RDFS is not a suitable foundation, its ability to fully describe resources is too weak, and it lacks a mechanism for logically constraining the meaning of terms , so it is obviously insufficient in semantic expression ability, so it cannot meet the semantic requirements of model verification

Embodiment Construction
[0032] The present invention will be described in detail below with reference to the drawings and specific embodiments, but the following embodiments are not intended to limit the present invention.
[0033] The common information model CIM defined by the IEC 61968 / 70 series of standards provides a set of common metadata semantics for the power system, and the schema uses a data description language to describe the relationship between metadata and metadata. A profile is a collection of classes, attributes, and relationships selected from a schema for specific business requirements, and the relationships are regulated. A specific CIM / XML file maps the CIM semantic information model and its extensions to a CIM / RDF application containing power system model information. Therefore, it must follow the CIM semantics and the restriction mechanism of a subset (Profile).
[0034] Therefore, the model verification proposed by the present invention is to compare the metadata information conta...

The invention discloses a body-based verification tool of a power grid public information model and a method of the body-based verification tool, wherein a model verification system which is provided for analyzing metadata information from a CIM / XML (Common Information Model / Extensive Makeup Language) power grid model, comparing the metadata information with a uniform standard information model and analyzing compatibility and semantic consistency of the model; and aiming at semantic requirements of model verification, an OWL (Web Ontology Language) main body language is adopted as the description language for integrating the body model, and a body integration verification method based on CIM Schema and CIM Profile is provided. According to the invention, the defect of power grid enterprise information integration bus on semantic specification and the problem of mismatching models occurring during mutual operation process are solved, thereby being beneficial to the specification in semantics of the information bus and convenient to the management of assembly models and the upgrading maintenance of CIM.
Description
Technical field [0001] The invention belongs to the field of power system information integration. The invention relates to a verification tool and method for an ontology-based grid public information model. Background technique [0002] With the continuous expansion of the scale of urban distribution networks, the application requirements of power companies have increased, and there is a large amount of information exchange between application systems. However, the information models of application systems developed by various departments are mostly established according to their own needs, lack of unified interface specifications, and internal functions are interleaved Overlapping and inconsistent data formats have caused a lot of redundancy. How to achieve seamless integration of business information has become a hot issue in the current informatization process of electric power enterprises. [0003] The International Electrotechnical Commission (IEC) has formulated the IEC 6197...
