Abstract

The invention discloses a heterogeneous information model mapping-based distribution network information interaction method and system. The method comprises the following steps of: obtaining basic models of different versions of CIM/XML power grid models, and analyzing the basic models into ontology models; traversing all the model elements in the ontology models, and obtaining a plurality of optimum mapping relationships between the elements according to degrees of similarities between the elements in different ontology models; storing each pair of optimum mapping relationships in a format of an XPath path expression; traversing all the XPath path expressions, and translating all the XPath paths of a mapping relationship file into an XSLT script comprising a corresponding template rule; and obtaining a to-be-processed source XML document, analyzing a class, an attribute and an association relationship in the source XML document to serve as to-be-transformed nodes, traversing all the to-be-transformed nodes to be matched with the XSLT script, and completing the transformation of each node through an XSLT processor so as to form a target XML document. The invention aims at solving the semantic conflict problems caused by model heterogeneity in traditional interoperation tests and power enterprise information integration processes.

Description

technical field [0001] The invention relates to the field of power system information integration, in particular to a distribution network information interaction method and system based on heterogeneous information model mapping. Background technique [0002] The rapid development of smart grid has brought a large number of cross-system interactive services. Due to the incompatibility of distributed application systems introduced by various business departments, electricity customers need to switch back and forth between subsystems, resulting in duplication of work, low efficiency, and the formation of "information islands". This not only increases the difficulty of information exchange, but also brings administrative obstacles. Standardization is an effective weapon to ensure data consistency and eliminate "information islands". Building an internationally common standard and a unified semantic grid information model is an ideal technical route and development direction. ...
