中低压配网自动化系统由主站、远方终端单元(RTU)、线路传感器、远方控制SF6 或真空开关、通信电缆等五个部分组成。中低压配电网自动化的应用有自己不同的特点:
a)传统的变电站RTU在功能上偏重遥信、遥测,但中低压配电网的自动化对象(开关房、开闭所和配电房)数目繁多,开关操作频繁,更注重遥信、遥控功能。
b)中低压配电网的自动化对象遍布城市、农村等各种不同环境,被不同层次的用电管理人员(包括农村电工)所操作。更要求其具有安装灵活、易操作、免专业维护、抗恶劣环境等特点。
c)应用于中低压配电网的RTU,在功能上应具有模块化结构,在硬件上要越简单、越可靠越好。好是同一套简单硬件,只要简单进行一下设置,就可以满足不同场合、不同规模的要求。
