Embodiment Construction

[0024] The specific implementation manner of the CIM / XML-based master-backup data heterogeneity method of the present invention will be described below with reference to the accompanying drawings.

[0025] As a text format for data exchange, XML can completely serve as a standard intermediate format, which reduces the cost of data conversion between heterogeneous databases and greatly improves the reusability of conversion programs. IEC 61970 series standards define the matching rules from UML (Unified Modeling Language) of CIM (Common Information Model) to CIM RDF Schema, see Table 1, so that the conversion from UML to CIM RDF Schema can be completed.

[0026] Among them, RDF is a resource description framework, which is used to represent metadata that machines can easily process; RDF Schema is a schema specification language that uses RDF to describe resources and their properties, including how resources are related to other resources.

[0027] After completing the conversi...

Abstract

The invention provides a host and backup data heterogeneous method based on CIM/XML. The mode mapping from an information model to a CIM/XML file and the data format mapping from CIM/XML to a relational database are designed, among heterogeneous databases, large object data exchanging is achieved with the assistance of CIM/XML, and on the basis, a three-layer model of data exchanging of the heterogeneous databases based on CIM/XML is put forward, description of all the heterogeneous databases and data conversion among data sources can be easily achieved, and thus the problems that lack of optimized query exists in current heterogeneous data integration, and the expandability of the data integration of the heterogeneous database based on Web is poor are solved.

Description

technical field [0001] The invention relates to the data processing technology of the electric power system, in particular to a CIM / XML-based master-standby data heterogeneous method. Background technique [0002] The main dispatching and backup dispatching systems in the power system are often independent of each other, and a unified heterogeneous data integration query platform has not been formed. It is difficult to exchange data and interoperate between systems. Under the complex model of power system, the interpretation efficiency is low when dealing with large data volume files. In addition, in the current heterogeneous data integration, there are problems of lack of optimized query and poor scalability of Web-based heterogeneous database data integration. Contents of the invention [0003] The invention provides a CIM / XML-based primary and backup data heterogeneous method, which can be applied to a complex model of a power system based on the CIM / XML document-base...
