【摘要】 目前，变电站自动化系统已经得到广泛的应用，然而，这些自动化系统主要是基于专用的解决方案或者协议。各种解决方案使得电力公司的非标准化的趋势变得越来越严重。由于不同的系统之间的信息交换常常需要进行兼容工作，这使得实时信息交换、系统集成以及数据维护的费用急剧增长，不利于变电站自动化系统的发展。另外，随着计算机和网络技术的飞速发展，自动化系统的基础条件如INTERNET技术、面向对象技术、多代理技术、安全防护技术等已经具备。因此，为了解决目前的问题并适应将来新技术的发展，迫切需要一种统一的、基于高级实现方法的新的标准。 IEC61850的目标就是为了明显的提高变电站自动化系统内的数据集成，降低工程费用，提高变电站整个生命周期中的灵活性。IEC61850不同于以往大多数的通信规约，它使用了设备功能和设备组件的对象模型。这些模型定义了标准的数据格式和通信服务，支持不同生产厂商产品之间的互操作和更容易的集成。标准不仅包括变电站内部的保护和控制等设备，还包括变电站之间以及变电站与控制中心的SCADA之间的接口。 本文首先介绍了IEC61850的产生背景、主要特点和内容。然后主要针对在控制中心与变电站之间的CORBA实现方法做了论述，其中本人进行了IEC61850信息模型的UML描述工作、将IEC61850映射为CORBA的主要方法研究、使用Java语言实现IEC61850的CORBA映射的具体方法研究，本文对上述工作进行总结。更多还原

【Abstract】 Automation systems in the area of power systems are widely accepted today, but they are mostly based on many proprietary solutions or standards. World-wide, electric utility deregulation is expanding for so many heterogeneous solutions. Utilities spend an ever-increasing amount for real-time information exchange, costs for system integration and data maintenance are exploding just for the compatible work of data exchanging between different systems, it is not propitious to the developing of automation system for power system. Additionally, with the rapid development of information technology, the base of automation system, for example INTERNET technology, Object-Oriented technology, Multi-Agent technology, Security technology, is mature. To meet today’s and future requirements a new standard with an advanced approach has been requested a few years ago.The objective of IEC61850 is to dramatically improve device data integration into information and automation technology, reduce the costs for engineering and increase the agility of the whole life cycle of a substation. IEC61850 differs from most previous utility protocols in its use of object models of device functions and device components. These models define common data formats and communication services, and support multivendor interoperability and ease of integration. The specification includes protection and control equipment in substation, interfaces between substations, as well as interfaces to supervisory control and data acquisition (SCADA) of control centers.This paper describes the background, main characteristics and contents of IEC61850 firstly. Then it introduces the method of mapping into CORBA of IEC61850 between control center and substations. As author’s main works, there are the UML description ways of IEC61850 models, main CORBA mapping ways of IEC61850 and the Java reality way of the mapping. The later part of this paper summarizes all these works.更多还原
