Research on low voltage distribution network topology generation method based on “transformer - distribution box - meter box - meter” model

Abstract

The current low voltage distribution network side has problems such as the inability to generate real-time and accurate topological relationships. Therefore, this paper analyzes the typical low-voltage distribution network structure to obtain the “transformer-distribution box-meter box-meter” model, which is based on the power outage event in the low-voltage distribution network station area. Restore power-on events and other data to study the classification status of low-voltage station areas, filter characteristic current and voltage sequences in each type of station area, and use voltage and current data to improve Tanimoto similarity coefficients to calculate distribution transformers and junction boxes in each group The correlation between the meter box and the electric meter realizes the high-efficiency and accurate identification of the low-voltage distribution network topology in real time, and improves the information control level of the low-voltage distribution network.
