User network topology recognition device and method for low-voltage areas

Abstract

The invention discloses a user network topology recognition device and method for low-voltage areas. The device comprises an electricity utilization information collection system which consists of a collector, a concentrator and a main station, wherein the collector is used for collecting electric energy information of an electric energy meter and exchanging data with the concentrator; the concentrator is used for collecting data of the collector or the electric energy meter and storing and processing data information required by area topology recognition; an area network topology recognitionsignal sent by the main station is obtained and stored area user data is uploaded to the main station; the main station is used for realizing a user network topology recognition algorithm for low-voltage areas and generating a final area network topological map; and a topology recognition instruction is sent to the concentration and data information uploaded by the concentrator is obtained. The device and method are capable of enhancing the informatization and intelligence levels of power distribution network management.

Description

technical field [0001] The invention belongs to the technical field of electric power automation, and in particular relates to a user network topology identification device and method for a low-voltage station area. Background technique [0002] With the rapid development of my country's urbanization and construction, the number of power users has increased significantly, and it is of great significance to realize the informatization and intelligence of distribution network power management. In the process of realizing informatization and intelligentization of distribution network management, many functions are inseparable from the topology information of the distribution network itself. [0003] In the low-voltage station area, due to insufficient attention to it in the past, many station areas lack jurisdictional user information, let alone the topological relationship between user points. The existing station area identification method is mainly based on carrier communic...

Problems solved by technology

[0005] 1. The method of recording the structure of the station area by means of observation and manual drawing by maintenance personnel operating in the low-voltage station area is inefficient, and unified digital storage cannot be realized, and there is no unified interface for further use of the system

[0006] 2. In the station area identification method based on carrier communication technology, the transformer cannot completely isolate the carrier signal. The carrier signal has cross-talk problems such as common high voltage, common ground, and common cable trench crosstalk, which leads to the accuracy of the identification method based on carrier communication technology. lower
