A method for actively researching and judging faults in low-voltage distribution networks based on intelligent distribution transformer terminals

Abstract

The present invention provides a method for actively researching and judging faults of low-voltage distribution networks based on intelligent distribution transformer terminals: the method is based on the real-time monitoring and monitoring of local information of distribution transformer stations, low-voltage branch boxes, electric meter boxes and user smart electric meters by intelligent distribution transformer terminals. Analysis, using the distributed edge computing function of the intelligent distribution transformer terminal, actively grasping the user's power outage events and carrying out on-site fault research and judgment, solved the problems of timeliness and information congestion caused by the traditional method of passive fault perception and centralized information collection and judgment, and realized Timely and active positioning of faults in the low-voltage distribution network to carry out fault repairs, reduce power outage time for users, and improve "active" service and high-quality service level.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a method for actively researching and judging faults in low-voltage distribution networks based on intelligent distribution transformer terminals. Background technique [0002] The low-voltage distribution network is the terminal link of the power distribution system and directly serves the users. According to statistics, the users of the low-voltage power grid account for more than 90% of the total power users. Emergency repairs are critical to improving power supply reliability and quality service levels. However, for a long time, the research and judgment of distribution network faults have mainly focused on the 10kV distribution network, ranging from substation outlet switches to 10kV branch lines. According to the statistics and analysis of distribution network faults in recent years, the low-voltage distribution network ( 0.4kV) faults account for more than 9...
