Low voltage distribution network is an important link in China's power system.In order to better adapt to the construction needs of smart grid,based on the Internet of Things and edge computing technology,by establishing a sensor node network,in the perception layer of the distribution network,real-time collection and monitoring of real-time operation conditions and equipment status of the distribution area are carried out,which realizes the real-time monitoring and risk warning of the overall operation status of the low-voltage distribution network and the distribution equipment,so as to improve the operation safety and equipment management level of the low-voltage distribution network.At the same time,combined with the automatic identification technology of network topology interchange,the accurate location and analysis of fault links and the closed-loop processing of abnormal problems are realized.A new scheme is proposed for the treatment of line loss and anti-theft,which improves the intelligent disposal and self-healing ability of the distribution network.
