Topology Identification Method Of Low-Voltage Substation

Abstract

This paper mainly studies the concept and scheme of a low-voltage substation distribution network topology identification system, which mainly includes topology identification end users and intelligent measurement controllers. The topology identification end users are usually set at the transformer outlet side of the transmission and distribution network; Intelligent measurement switch is divided into main control module, detection function and communication module, including topology identification flow generation function; The topology identification client is used to poll the position of each intelligent measurement controller through the communication module, and sequentially transmit the topology identification instruction to each intelligent measurement controller through the address block. The topology identification flow generation function of each intelligent measurement controller is used to generate the topology identification flow pressure information after receiving the topology identification instruction; The monitoring function of each intelligent measurement controller is used to collect topology identification flow pressure information; The topology identification port then passes through each intelligent measurement switch and checks whether it can collect the topology identification current information for topology identification. This technology has the advantages of simple structure, simple operation and accurate judgment.
