摘　　要：东北冬季低温寒冷地区对配电网自动化控制终端的保护动作时间和液晶屏、CPU等本体设备造成影响,在同66 kV变电站10 kV线路出口保护的配合中存在很大问题。在配电网自动化设备的运行和维护中,存在问题包括现阶段配电网网架规划和布局的不合理,配电网自动化设备选型及布局的不合理,配电网自动化终端设备运维和故障抢修人员的缺失。结合东北冬季低温寒冷地区对自动化设备可靠性的影响及配电网网架的基本情况,提出配电网自动化系统保护方案,实施架空线路三分段三联络,电缆线路环网运行,时序逻辑控制保护的配电网自动化建设和运行模式。The low temperature and cold area in winter of northeast China affects the protection operation time of distribution network automation control terminal,LCD,CPU and other ontology devices.Therefore,it is faced with problems in the coordination with the 10 kV line outlet protection of 66 kV substation.The problems exposed in the operation and maintenance of distribution network automation equipment have gradually emerged,including the unreasonable distribution network frame planning and layout at the present stage,the unreasonable selection and layout of distribution network automation equipment,and the lack of operation and fault repair personnel of distribution network automation terminal equipment.Combined with the influence of low temperature and cold area in winter of northeast China on the reliability of automation devices and the basic situation of distribution network frame,it puts forward the protection scheme for distribution network automation system,implements three sections and three connections of overhead lines,loops network operation of cable lines,and completes automatic construction and operation mode of distribution network protected by sequential logic control.
