[0002] In modern society, power supply is crucial to people's daily life, industrial production and various social activities. As the key link between the power system and the user, the operation status of the low-voltage distribution network directly affects the reliability and power quality of power supply. However, the low-voltage distribution network has the characteristics of wide distribution, complex structure, numerous equipment and diverse operating environment, which makes it face many factors that may cause faults. Modern society has higher standards for the stability and continuity of power supply, and any temporary power outage may cause great losses to some power-sensitive industries (such as electronic chip manufacturing, medical equipment operation, etc.). In order to monitor the operation status of the low-voltage distribution network in real time, accurately detect and locate faults, fault real-time monitoring equipment terminals are often installed in the low-voltage distribution network. Through advanced sensor technology, communication technology and data analysis algorithm, various operating parameters such as current, voltage and power in the low-voltage distribution network can be collected in real time, and the data can be transmitted to the background monitoring center through a reliable communication network. Using big data analysis and intelligent diagnosis technology, the monitoring center can deeply mine and analyze these data to quickly determine whether there is a fault and the type and location of the fault, realize real-time monitoring and rapid positioning of low-voltage distribution network faults, effectively improve the operation management level and power supply reliability of the low-voltage distribution network, and meet the demand of modern society for high-quality power supply.
