Problems solved by technology

During the construction of the low-voltage distribution network, there are errors in the file of the user's electric meter line or the change of the electric meter file during maintenance. analysis, etc. have a great impact
The traditional low-voltage distribution network topology identification detection mainly relies on manual inspection means, that is, according to the distribution and direction of the distribution network in the low-voltage station area, the hand-held household variable identification instrument is used to conduct a manual survey section by section. Many, cable trenches or overhead lines are laid in parallel, the inspection is not only inefficient and costly, but also cannot obtain real-time and accurate topological information of household substations in low-voltage station areas

Description

technical field [0001] The invention relates to the field of station operation monitoring, in particular to an intelligent monitoring system for the operation state of a low-voltage station area. Background technique [0002] The low-voltage distribution network is a terminal network that directly supplies power to users. It undertakes the key function of transmitting domestic electricity at the end of the power network and is an important part of the power grid. During the construction of the low-voltage distribution network, the user's meter line file is wrong or the changed meter file is not recorded or wrongly recorded. analysis and so on. The traditional low-voltage distribution network topology identification and detection mainly relies on manual inspection methods, that is, according to the distribution and trend of the low-voltage distribution network in the low-voltage station area, the hand-held household transformer identification instrument is used to perform ma...
