A system and method for dynamic identification of electrical network topology in a low-voltage distribution station area

Abstract

The invention discloses a system and method for dynamic identification of the topology of a low-voltage distribution station area electrical network, which includes a station area identification terminal of a master, a branch identification terminal of a slave machine, and an end identification terminal of a slave machine; the station area identification terminal is installed in a transformer The outlet terminal is used for phase-separated real-time broadcasting of the station identification signal of the station identification terminal and the reception of the terminal identification signal of the terminal identification terminal; the branch identification terminal is installed at the branch end of the line and is used to receive the station area of ​​the station identification terminal in real time The identification signal and the terminal identification signal of the terminal identification terminal; the terminal identification terminal is installed at the end of the meter box, and is used to receive the station area identification signal of the station area identification terminal and send the terminal identification signal of the terminal identification terminal in real time. The invention can efficiently and accurately establish the topological relationship among distribution transformer-line-household, provide household-transformer relationship for fast fault location of low-voltage line, and improve distribution network operation and maintenance management level and power supply reliability of distribution network.

Description

technical field [0001] The invention belongs to the technical field of distribution networks, and specifically relates to a system and method for dynamic identification of electrical network topology in a low-voltage distribution station area.
