Title:
AUTOMATIC TOPOLOGY IDENTIFICATION METHOD AND SYSTEM FOR ELECTRIC POWER INTELLIGENT TRANSFORMER AREA
Document Type and Number:
WIPO Patent Application WO/2022/088192
Kind Code:
A1
Abstract:
The present application relates to the field of intelligent application of electric power transformer areas, and relates to an automatic topology identification method and system for an electric power intelligent transformer area. In the present application, signals transmitted on a power line are changed into one-way transmission; for identification signals only transmitted from top to bottom or from bottom to top(one-way transmission), all transverse signals and signals from bottom to top (in a mode from top to bottom) or from top to bottom (in a mode from bottom to top) are shielded, such that the signals can only be transmitted in one direction to form a directed root tree structure, a topological relationship between the signals and the directed root tree structure is accurately identified, and the identification signals are transmitted downwards step by step to a tail end (an electric meter), and finally, a complete and accurate transformer area topological relationship is formed. The present application allows for improvement of the automation level of a low-voltage distribution area, and solves the problems of incomplete topological relationship, disordered communication, and the like of a low-voltage distribution transformer area in the current distribution automation master station system.
