配电系统是电力系统直接面向广大用户的一个重要环节。为了全面提高配电网运营的各项技术经济指标，配电网自动化系统的建设势在必行。配电自动化系统是将配电网在线数据和离线数据、配电网数据和用户数据、电网结构和地理图形进行信息集成，构成完整的自动化系统，实现配电系统正常运行及事故情况下的监测、保护、控制、用电和配电管理的现代化。
本文结合国外配电网自动化系统的发展趋势，和国内配电网自动化系统发展的现状，对配电网系统的接线形式、配电设备和继电保护情况给出了概述和分析，并对同一材料类型的接线和设备进行了大概的比较。本文结合配电网自动化系统接线和设备的分析对某市的配电网自动化系统进行接线设计和其设备选型，并设置了继电保护。通过具体的分析比较单纯的环网电缆方案和市内架空线路和电缆线路混合式接线方式，得到提出的架空线和电缆接线相结合的方式是更合适的，并对该线路进行了设备选型。

Power distribution system is system-oriented users direct an important part. In order to comprehensively improve the distribution network operated by various technical and economic indicators, distribution automation system it is imperative to the building. Distribution automation system is online data distribution network and off-line data, the distribution of data and user data, network structure and geographic information integrated graphics, provide a complete automation system achieving distribution system and the normal operation of an accident of the monitoring, protection, control, management and distribution of electricity modernization. Based foreign distribution automation system development trend, and domestic distribution automation system development status, Distribution of the wiring system forms, distribution of equipment and protection given an overview and analysis as well as the same type of wiring material and equipment, about the comparison. Based on distributio
