【摘要】 随着电力系统自动化水平的不断提高与信息化的不断深入,标准化成为能量管理系统(Energy Management System,EMS)发展的必然之路。IEC-61970标准的公共信息模型--CIM(Common information model)提供了用于不同能量管理系统(EMS)间交互数据的一个实用化的数据模型; IEC-61970标准的组件接口规范--CIS(Component Interface Specification)是在CIM基础上定义的,规定组件(或应用程序)为了能够以一种标准方式和其它的组件(或应用程序)交换信息而应该实现的各种接口。数据访问设施(Data Access Facility, DAF)是OMG发布的国际标准,IEC-61970引入了DAF技术作为其CIS的基本接口。在基于CIM/CIS的EMS系统间交互信息是以CIM/XML为载体,而CIM/XML数据本质上是CIM语义的RDF数据。本文在开发基于CIM模型的EMS数据支撑系统中,通过引入专于RDF的JENA技术来处理CIM/XML,着重讨论了JENA对RDF数据的表达、解析、查询技术在CIM/CIS中的应用。JENA不仅能自动地生成CIM/XML数据,而且可以高效地对CIM/XML进行查询从而可以进一步实现CIS的DAF接口。JENA技术为IEC-61970标准的进一步的实用提供了一条新的有效途径。第一章介绍了本论文的课题背景及研究意义。第二章研究了IEC-61970标准体系结构以及CIM模型与CIS接口。第三章阐述了搭建基于CIM模型的EMS数据支撑系统中使用的相关技术。包括资源描述框架(Resource Description Framework,RDF)、JENA技术、公共对象请求代理结构(CommonObject Request Broker Architecture,CORBA)。第四章引入JENA技术,研究了如何把数据从既有电力系统的关系数据库导出到CIM/XML文件的过程,完成了基于JENA技术的CIM对象数据库构建。第五章在深入研究数据访问设施(DAF)以及公共对象请求代理结构(CORBA)分布式组件技术的基础上,通过JENA的SparQL语言查询RDF数据实现了CIS中主要的接口服务--DAF。更多还原

【Abstract】 The continuous improvement of the automation of Electric power system in information age renders Standardization as an inexorable trend for Energy Management Sysetm (EMS). Common information model (CIM) of IEC-61970 provided a common model for exchanging in different EMS. Based on CIM, Component Interface Specification (CIS) of IEC-61970 afford a standard interface for data accessing and employed the International standard Data Access Facility (DAF) released by the OMG as its basic interface.CIM/XML,as a carrier of exchange information on EMS systems is essentially based on RDF technology. In the development of EMS, JENA technology that focused on RDF has been introduced to process CIM/XML. JENA can automatically produce CIM/XML data, and highly effective query helping to Implementation of CIS. JENA technology provides a new and effective way to practical for IEC 61970 standard.In the chapter 1, the purpose and background of this paper are introduced.In the chapter 2, the IEC-61970 Specification as well as the CIM and CIS interface is presented.In the chapter 3, the key technology used in the EMS system on the basis of CIM, which includes RDF, JENA and CORBA is illustrated.In the chapter 4, JENA technology is used for CIM data processing, the procedure of export data from EMS database to CIM/XML file is discussed in details and a new object database of CIM was created based on JENA technology.In chapter 5, DAF and distributed component technology based Common Object Request Broker Architecture (CORBA) is further discussed in the first place and then the main interface service RDF of CIS was implemented with the use of SparQL inquiry language on the basis of JENA.更多还原
