【摘要】：本文在分析了电力信息化的发展所带来的信息冗余、信息爆炸和信息孤岛等问题的基础上,针对电力应用异构数据集成的迫切需求,深入研究了基于语义的电力应用数据共享与集成方法,在电力工业统一标准的基础上,基于关系数据库和XML数据源等电力企业两大核心数据源,提出了基于CIM模型的语义数据集成框架。 本文首先研究了公共信息模型(CIM)、资源描述框架(RDF)等进行电力系统语义数据集成所需的相关技术。在深入理解电力系统CIM模型规范和结构的基础上,采用语义网技术和工具,构建了符合CIM标准的语义数据模型。然后基于标准语义模型模型,依据软件工程的思想详细设计了基于Jena框架的异构数据源关系数据库和XML的集成系统,并对每个功能设计和模块划分进行详细阐述。最后,在MyEclipse开发环境中,采用Java语言和Jena框架,在本体和推理框架的支持下实现了符合电力系统标准的异构数据语义集成,完成了异构数据的语义集成和用户查询的目标,达到了电力数据语义信息共享的目的。 语义网技术在信息集成方面的应用,为电力数据集成发展带来了新的方向。随着语义网技术和电力数据集成结合的发展,将更好的实现电力系统语义数据共享,为智能电网的发展提供语义帮助,使智能电网更好的提供智能化服务。
[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.
