Unifying method and device of data model

Abstract

The invention provides a unifying method and device of a data model. The method includes the steps that firstly, consistency verification is conducted on CIM/XML documents, full-model import is conducted on data which are verified to be correct, and a single line diagram is generated; a correct device is configured for the single line diagram in a topologic mode, full-model export is conducted, and then standard CIM/SVG files are generated. Due to the fact that consistency verification is conducted on the CIM/XML documents before import, part of incorrect data are deleted, full-model import and export are conducted, the standard CIM/SVG files are generated, and then the CIM/XML documents can be converted into the standard CIM/SVG files. The method solves the problems of semantic inconsistency caused by different extensions of different applications to CIM and frequent replacement of CIM versions, distribution network data migration between the heterogeneous systems is achieved, and high integration and sharing of smart power grid information are achieved.

Description

technical field [0001] The invention relates to the field of data migration of electric power systems, in particular to a method and device for unifying data models. Background technique [0002] The power system is led by different business departments to develop various information systems. The design ideas and models of each system are very different. Therefore, it is difficult to realize information sharing and data fusion between heterogeneous systems. Data cleaning and migration between systems could not be successfully implemented. At present, the State Grid Corporation of China is vigorously promoting the production management system (PMS) for asset lean management throughout the company. During the promotion period, it is necessary to realize the data migration and merging of the original heterogeneous systems. Data mutual guidance, based on the absence of a unified power system data model, will inevitably cause data import errors during the data migration process,...

[0002] The power system is led by different business departments to develop various information systems. The design ideas and models of each system are very different. Therefore, it is difficult to realize information sharing and data fusion between heterogeneous systems. Data cleaning and migration between systems unable to implement smoothly

At present, the State Grid Corporation of China is vigorously promoting the production management system (PMS) for asset lean management throughout the company. During the promotion period, it is necessary to realize the data migration and merging of the original heterogeneous systems. Data mutual guidance, based on the absence of a unified power system data model, will inevitably cause data import errors during the data migration process, and eventually cause data migration between systems to fail
