【摘要】：本文在分析了電力信息化的發(fā)展所帶來的信息冗余、信息爆炸和信息孤島等問題的基礎(chǔ)上,針對電力應(yīng)用異構(gòu)數(shù)據(jù)集成的迫切需求,深入研究了基于語義的電力應(yīng)用數(shù)據(jù)共享與集成方法,在電力工業(yè)統(tǒng)一標準的基礎(chǔ)上,基于關(guān)系數(shù)據(jù)庫和XML數(shù)據(jù)源等電力企業(yè)兩大核心數(shù)據(jù)源,提出了基于CIM模型的語義數(shù)據(jù)集成框架。 本文首先研究了公共信息模型(CIM)、資源描述框架(RDF)等進行電力系統(tǒng)語義數(shù)據(jù)集成所需的相關(guān)技術(shù)。在深入理解電力系統(tǒng)CIM模型規(guī)范和結(jié)構(gòu)的基礎(chǔ)上,采用語義網(wǎng)技術(shù)和工具,構(gòu)建了符合CIM標準的語義數(shù)據(jù)模型。然后基于標準語義模型模型,依據(jù)軟件工程的思想詳細設(shè)計了基于Jena框架的異構(gòu)數(shù)據(jù)源關(guān)系數(shù)據(jù)庫和XML的集成系統(tǒng),并對每個功能設(shè)計和模塊劃分進行詳細闡述。最后,在MyEclipse開發(fā)環(huán)境中,采用Java語言和Jena框架,在本體和推理框架的支持下實現(xiàn)了符合電力系統(tǒng)標準的異構(gòu)數(shù)據(jù)語義集成,完成了異構(gòu)數(shù)據(jù)的語義集成和用戶查詢的目標,達到了電力數(shù)據(jù)語義信息共享的目的。 語義網(wǎng)技術(shù)在信息集成方面的應(yīng)用,為電力數(shù)據(jù)集成發(fā)展帶來了新的方向。隨著語義網(wǎng)技術(shù)和電力數(shù)據(jù)集成結(jié)合的發(fā)展,將更好的實現(xiàn)電力系統(tǒng)語義數(shù)據(jù)共享,為智能電網(wǎng)的發(fā)展提供語義幫助,使智能電網(wǎng)更好的提供智能化服務(wù)。
[Abstract]:Based on the analysis of the problems of information redundancy, information explosion and information isolation brought by the development of electric power informatization, this paper aims at the urgent need of heterogeneous data integration in electric power applications. The method of data sharing and integration based on semantics is deeply studied. Based on the unified standard of power industry and the two core data sources of power enterprise, such as relational database and XML data source, A semantic data integration framework based on CIM model is proposed. In this paper, we first study the relevant technologies for power system semantic data integration such as Common Information Model (CIM), Resource description Framework (RDF) and so on. On the basis of deeply understanding the specification and structure of CIM model in power system, a semantic data model conforming to CIM standard is constructed by using semantic web technology and tools. Then, based on the standard semantic model and the idea of software engineering, the integration system of heterogeneous data source relational database and XML based on Jena framework is designed in detail, and each function design and module partition are described in detail. Finally, in the MyEclipse development environment, Java language and Jena framework are used to realize semantic integration of heterogeneous data in accordance with the standards of power system, with the support of ontology and reasoning framework, and the goal of semantic integration and user query of heterogeneous data is achieved. The purpose of power data semantic information sharing is achieved. The application of semantic Web technology in information integration brings a new direction for the development of power data integration. With the development of the combination of semantic Web technology and power data integration, the semantic data sharing of power system will be better realized, which will provide semantic help for the development of smart grid and make smart grid provide intelligent service better.
