Abstract
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...
