虚拟化与信息整合技术在电力调度中心的应用

信息系统整合可以分为硬件整合、数据整合、软件模块整合、业务流程整合和应用访问整合 5个层次。以电力调度中心不同应用系统的整合为背景，就整合的不同层次提出了整合方案:硬件层次上的整合方案是引入虚拟化技术，基于VMware ESX Server平台虚拟化不同应用需要的硬件和操作系统环境，实现对服务器的整合;数据层次上的整合方案是建立符合调度网络和数据特点的数据中心;软件模块层次上的整合方案是创建构件库对电力领域的软件构件进行管理、开发和重构;业务流程层次上的整合方案是引入符合工作流管理联盟（WFMC）标准的工作流管理系统，对分散于企业内部或外部各个信息系统中的“业务流程断点”进行链接，进而完成全程业务活动的自动化;应用访问层次上的整合方案是使用Portal和Web服务技术以实现应用程序统一访问和集成。

Application of Virtualization and Information Integration Technology in a Power Dispatching Center

Information integration can be divided into five levels,i.e.,hardware integration,data integration,software module integration,business process integration,and application access integration.In order to realize the information integration of various application systems in a power dispatching center,this paper proposes specific and detailed integration schemes for the five levels.The hardware integration scheme can be realized by using virtualization technology,and the hardware and operating system can be virtualized for different applications based on the VMware ESX Server platform.The data integration scheme can be achieved by establishing a data center which accords with the characteristics of power system data.The software module integration program can be carried out by establishing the component library,which is used to manage,develop and reuse the software components.The business process integration can be realized by introducing a standard work flow management system,connecting the "business process breakpoints" of the internal or external information systems,so as to form a complete fully-automated business process.The application access integration scheme can be realized by using Portal technology and Web services technology to achieve the unified access and integration of various application systems.
