Problems solved by technology

In this way, the corresponding relationship between the terminal identification code of each monitoring terminal and the monitoring terminal needs to be known in advance, and the physical relationship between the terminals needs to be known. This kind of scheme is complicated, and a lot of information needs to be known in advance, and the user variable relationship is not recognized

Abstract

The application discloses an identification method and system for the low-voltage distribution court topology. The method comprises: establishing a communication network between communication nodes; loading a power carrier signal in a distribution transformer; and generating a low-voltage distribution court topology based on signal-to-noise ratio information of carriers in mutual communication between communication nodes. According to the application, on the basis of combination of carrier signal-to-noise ratio information with phase information, the network topological relationship of the low-voltage distribution court is obtained in real time to complete household-transformer correspondence relationship identification. The real-time performance is good; the manpower is saved; and the accuracy is high.

Description

technical field [0001] The present application relates to the technical field of topology identification, and in particular to a topology identification method and system for a low-voltage distribution station area. Background technique [0002] In the distribution network, the premise of realizing the intelligent monitoring of station area distribution is that the topology structure of the station area is known, but in the daily operation and maintenance management of power distribution, there are often unclear connections between households and substations, especially in newly built stations. The topology cannot be obtained directly at all, and manual inspection is required, which results in a huge workload, resulting in a waste of manpower and material resources. Moreover, this method also has the risk of inaccurate acquisition of the topology of the station area. At the same time, when the topology of the station area changes, it cannot be found in time. The problem has ...
