【摘要】 配电自动化是近几年发展起来的新兴技术和领域，是电力系统现代化的必然趋势。配电自动化系统是应用现代电子技术、通信技术、计算机及网络技术，将配电网实时信息、离线信息、用户信息、电网结构参数、地理信息进行安全集成，构成完整的自动化及管理系统。在配网自动化的建设中，通信规约和通信方式的选择与实现是一个非常重要的环节，是实现数据和命令快速、可靠传递的基础。 馈线自动化是配电自动化系统的主要功能之一。本文主要研究了馈线自动化系统中通信的实现及对采集数据进行存取、分析和利用的方法。文章首先综述了配电自动化系统和馈线自动化系统，并对两者的关系及功能作了分析和探讨；第二章研究了配电自动化系统的通信系统及采用的规约。分析了DL／T634—1997规约及其特点，并与DNP3.0规约作了比较。探讨了DL／T634—1997规约在馈线自动化系统中的实现方法；第三章研究了馈线自动化系统通信的编程实现。采用面向对象编程技术，完成了后台通信程序的设计；第四章研究了采集数据的显示、存取和分析。探讨了Sql Server数据表的设计方法及如何对采集数据进行显示、存取、分析和利用。更多还原

【Abstract】 Distribution Automation is a new technology and domain developing in recent years. It’s the inevitable trend of power system modernization. Distribution Automation System is automation and supervising system which applyies modern electron, communications, computer and network technology to integrating distribution system real time information, off-line information, user information, electric network structural parameter and geographic information. For distribution automation, the selection and realization of communications protocol and mode is an important tache, and is the foundation of data and order transferred speedily and reliably.Feeder Automation is one of the most important functions of Distribution Automation System. This paper studies the realization of communication and the method of accessing, analyzing and utilizing data acquisition. First it summarizes distribution automation system and feeder automation system, introduces their relationships, researches and analyzes functions should be realized. In chapter two, we research communication system and adoptive protocols of distribution automation system. DL/T634-1997 protocol is presented and it’s characteristic is analyzed, and is compared with DNP3.0 protocol. How to apply this protocol to feeder automation system is also discussed in this chapter. In chapter three, we research the communication programming of feeder automation system, adopt object-oriented technology, finished the design of communication program. In chapter four, the methods of displaying, accessing and utilizing data acquisition are researched. The design way of Sql Server table and how to display, access, analyze and utilize data acquisition are discussed in detail.更多还原
