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 in conjunction with the accompanying 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 standard provides a set of common metadata semantics for the power system, and the schema (Schema) uses a certain data description language to describe the relationship between metadata and metadata. A subset (Profile) is a set of classes, attributes, and relationships selected from a schema (Schema) for a specific business requirement, and the relationships are constrained and standardized. A specific CIM / XML file maps the CIM semantic information model and its extensions to a CIM / RDF application containing power system model information, so it must follow the CIM semantics and the constraint mechanism of the subset (Profile).

[0034] Therefore, the model verification proposed by the prese...

Abstract

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, and relates to an ontology-based verification tool and method for a public information model of a power grid. Background technique [0002] With the continuous expansion of the scale of the urban distribution network, the application requirements of power enterprises have increased, and there is a large amount of information exchange between application systems. However, the information models of the application systems developed by various departments are mostly established according to their own needs, lacking unified interface specifications, and internal functions. Overlapping and non-uniform data formats result in a large amount of redundancy. How to realize the seamless integration of business information has become a hot issue in the process of power enterprise informatization. [0003] The International Electrotechnical Commission (IEC) has formulated the IEC 61970 / 6196...
