A true test research of topology identification technology for low voltage distribution networks

Abstract

Architectural topologies of low voltage distribution networks are hard to “figure out” and “poor in interaction”. Therefore， many topology identification methods have been proposed， most of which have been simulated rather than tested on lines. Thus， low-voltage distribution network topology identification technology testing is investigated using a next-generation true test platform. Firstly， the next-generation true test platform established in Wuhan UHVAC testing base is introduced. Then the test scheme of low-voltage distribution network topology identification technology is proposed. Finally， the test of low-voltage distribution network topology identification technology is carried out to verify the effectiveness of the carrier communication method in the topology identification method and the platform's superiority.
