【摘要】：近年来,计算机技术、信息处理技术和网络通信技术发展迅速,对变电站自动化系统产生了巨大影响。随着特高压、大容量、超大系统电网的逐渐形成,对电网安全、稳定、可靠、控制、信息交互等提出了更高更迫切的要求。基于IEC61850系列标准可以实现变电站的集成化、智能化和信息化,使厂站自动化设备从结构上、配置上、技术性能上和应用上出现巨大的变化,促使变电站自动化系统结构由变电站层、间隔层的二层结构向变电站层、间隔层、过程层三层结构过渡,将实现厂站监控系统的无缝信息交换,建立开放式结构,实现资源的优化和整合。IEC61850采用对象建模技术,面向设备建模和自我描述的思想,实现所有厂家的智能设备互操作的目标,提升了系统的水平,丰富了变电站智能化技术的内涵,为智能化变电站技术健康发展不断提供可靠支撑。本文阐述了智能变电站发展历史和现状,多角度全方位详细分析了本文所研究的智能信息处理子站;文章从智能变电站对信息子站的功能需求出发,研究了智能信息处理子站的几项关键技术,综合了现有通讯管理机的现状,提出了基于嵌入式硬件平台以及嵌入式Linux操作系统的软件系统总体方案架构。文章描述了采用面向对象的OOA方法设计的智能信息处理子站软件结构并就其中的程序化控制等关键技术提出了具体的实现方法,最后本文举例说明了智能信息处理子站在智能变电站的应用情况并展望了采用先进的软硬件平台智能信息子站的美好的未来及其重要的现实意义。
[Abstract]:In recent years, computer technology, information processing technology and network communication technology rapid development, has a great impact on the substation automation system. With the ultra high voltage, large capacity, gradually formed a large system of power grid, the grid security, stability, reliability, control, information exchange and put forward more and more urgent requirements can be integrated. The IEC61850 series of standards implementation of substation based on intelligence and information, the station automation equipment from the structure, configuration, great changes on technical performance and application, the substation automation system structure by the substation layer, the two layer structure of interlayer spacing to the substation layer, layer, process layer three layer structure the transition will achieve seamless information exchange station monitoring system, the establishment of the open structure, realize resource optimization and integration of.IEC61850 with object modeling technology to device modeling and self description The idea of achieving the goal of interoperability of intelligent devices of all manufacturers improves the level of the system, enriches the connotation of substation intelligent technology, and provides reliable support for the healthy development of intelligent substation technology.
This paper describes the history and current situation of intelligent substation development, multi angle comprehensive detailed analysis of the intelligent information processing substation; article based on information sub station from the functional requirements of intelligent substation, studied several key technologies of intelligent information processing substation, comprehensive status of the existing communication management machine, put forward the architecture of the overall scheme of the software system and the embedded hardware platform based on embedded Linux operating system. This paper describes the design method of the OOA object oriented intelligent information processing substation software structure and the key technology of program control and put forward the concrete realization method, finally this paper illustrates the application of intelligent information processing in sub station the situation and Prospect of intelligent substation using advanced software and hardware platform of intelligent information sub station bright future and important practical significance.
