基于CORBA分布式对象技术的新一代电网调度自动化系统的应用研究

本文介绍了分布式对象技术及其在新一代电网调度自动化系统中的应用。IEC 61970标准是为电力系统客体建立公用信息模型（CIM）并对所有应用之间的逻辑信息交换形成组件接口规格（CIS）。IEC 61970标准是数据模型的理论基础,而分布式对象技术则是实现这个系统的技术保证。每个应用,每项服务或每个子系统可以描述为一个或多个组件。所有组件由一个集成框架相互连接,该框架由对象请求代理（ORB）总线组成,这也就是公共对象请求代理体系结构（CORBA）的核心。本文回顾了开发遵循IEC 61970标准的新一代电网调度自动化系统的背景,基于大量有关CORBA性能测试的数据,讨论了采用基于CORBA分布式对象技术的可行性。CORBA应用的两种主要的方法是建立系统集成框架和封装现有的应用或程序。最后,本文给出并分析了调度自动化系统的整体系统结构及设计方案。

Applying Study of CORBA-based Distributed Object Technology to Next Generation of Power Dispatching Automation System

The distributed object technology and its application in the next generation of a power dispatching automation system are introduced.Standard IEC 61 970 is to found Common Information Model（CIM） for the power system objects and to form Component Interface specifications（CIS） for logical information exchanges among all application.Standard IEC 61970 is the theoretical base of date models and distributed object technology is the technology guarantee of implementing this system.Each application,each service or each sub-system can be described as one or more components.All components are interconnected by an intergration framework,which is composed of Object Resquest Broker（ORB） bus,namely the core of Common Object Request Broker Architecture（CORBA）.In this paper,the background of developing a next generation of a power dispatching automation system complying with Standard IEC 61970 is reviewed.On the basis of a lot of testing data about CORBA performance,the feasibility of adopting CORBA-based distributed object technology is discussed.Constructing integration framework of the system and encapsulating the existing applications or programs are two main methods about CORBA applications.Lastly,the whole system structure and its design scheme of the dispatching automation system are presented and analyzed.
