Line loss monitoring system and method based on distribution transformer terminal

The invention discloses a line loss monitoring system based on a distribution transformer terminal. Internet-of-things transformation is carried out on the distribution transformer network from four levels of cloud, management, side and end. GPS timing is set, data is collected and line loss is calculated synchronously, and comprehensive dead-angle-free synchronous line loss real-time online monitoring from medium voltage to low voltage is realized. Line loss abnormal conditions of all sections of the medium-voltage to low-voltage line are accurately analyzed, a real-time and comprehensive low-voltage transformer area line loss monitoring method is provided, a data basis is provided for line aging analysis, insulation risk estimation, timely acquisition of electricity stealing informationand other conditions, and the power grid electricity utilization quality and the overall operation level are improved. 本发明公开了一种基于配变终端的线损监测系统，从云、管、边、端四个层次对配变网进行物联网化改造，设置GPS对时，同步采集数据和计算线损，实现了中压到低压全面无死角的同期线损实时在线监测，精确分析中压到低压线路各区段
