摘　　要：目前台区侧智能监测设备型号繁杂,但功能均相对单一,现场没有足够空间安装如此众多的监测类设备。2020年国网推出配电台区智慧物联体系应用场景典型设计方案,按照“云管边端”总体框架,定义了配电台区低压、线路和用户等端侧感知单元(即:智能低压故障传感器装置)的功能和要求。故障传感器装置不仅融入了配电台区物联体系,而且可有效取代目前存在的大部分台区侧各类监测单元,满足台区级运行管理所要求的故障检测、拓扑辨识、负荷监测、有序用电、停复电上报等诸多功能,有效提升供电公司对台区的管理水平,提高了电网运行的可靠性。At present,the models of intelligent monitoring equipment at the station side are complex,but the functions are relatively single.There is not enough space to install so many monitoring equipment at the site.In 2020,the State Grid launched a typical design scheme for the application scenario of the intelligent Internet of Things system in the distribution station area.According to the overall framework of“cloud management side end”,it defined the functions and requirements of the end-side sensing units(i.e.,intelligent low-voltage fault sensor device)in the distribution station area,such as low-voltage,line and user.The fault sensor device not only integrates the IoT system in the distribution station area,but also can effectively replace most of the existing monitoring units at the station area side,meet the many functions required by the station area operation management,such as fault detection,topology identification,load monitoring,orderly power use,power outage and recovery reporting,effectively improve the management level of the power supply company on the station area,and improve the reliability of the power grid operation.
