Power grid topology identification method and system

Abstract

The invention discloses a power grid topology identification method and system. The method comprises the following steps that a gateway terminal carries out broadcast timing of a topology signal identification device and a topology signal generation device, and transmits a topology signal generation instruction; the topological signal generation device simulates the electricity utilization of a user according to the instruction to generate a topological signal; the topology signal identification device on each branch line node identifies the topology signal and performs association storage according to the address information of the topology signal generation device; and the gateway terminal carries out traversal query on the storage information of all the topological signal identification devices at a period T and obtains the storage information, and establishes a topological information base. According to the invention, through a reasonable carrier communication topological information acquisition mechanism, a topological information base can be continuously acquired and perfected through on-site communication traversal; and a topology tree is adopted to carry out topology identification on the on-site complex user-to-transformer line relationship so that the complex user-to-transformer line relationship is visualized and can be better displayed.

Description

technical field [0001] The invention relates to the technical field of grid topology identification, in particular to a grid topology identification method and system. Background technique [0002] At present, the lines in the electric low-voltage residential station area are intricate, especially in the old station area. The lines are intricate, and it is impossible to accurately distinguish the actual line routing. The fire hazards caused by the aging and complex intertwining of lines in the old residential area, and the difficulty of troubleshooting line faults have greatly increased the workload of construction workers on the electric power site. It has also become an obstacle to the intelligent transformation of the Taiwan area. In order to realize the intelligent management of the station area, a technology is urgently needed to accurately sort out the topological relationship of the on-site station area lines. The grid station area topology identification system is a...
