Transformer area user automatic identification system

Abstract

A transformer area user automatic identification system is characterized by comprising a transformer area identification information controller, a user electric energy meter identification information gatherer and a backstage computer management system; the transformer area identification information controller mainly comprises a GPRS communication interface circuit, a three phase power frequency communication signal modulation circuit, a three phase power frequency communication signal sampling circuit, a three phase voltage zero crossing detection circuit, and a microprocessor circuit; the user electric energy meter identification information gatherer mainly comprises a RS485 communication interface circuit, a single phase power frequency communication signal modulation circuit, a single phase power frequency communication signal sampling circuit, a single phase voltage zero crossing detection circuit, and a microprocessor control circuit; the backstage computer management system mainly comprises a computer, a data base management system and a GPRS communication device. The backstage computer management system can be directly used to obtain user identification information function of each transformer area in a power grid, thereby improving transformer area user general survey work efficiency and automation degree.

Description

technical field [0001] The invention relates to the field of load balance management of a low-voltage distribution network, in particular to an automatic user identification system in a station area. Background technique [0002] When the power sector maintains and manages the operation of the power grid, it often adjusts, increases or decreases the transformers of the distribution network and the electric energy meters of the affiliated users according to the change of the load of the distribution network. After the adjustment, increase or decrease of users in the station area, the original station area and phase affiliation of some electric energy meters have changed. How to judge which distribution transformer and which phase the user electric energy meter belongs to in the intricate distribution lines, Accurately grasping users' station areas and different attributes is necessary for rationally allocating user loads, reducing line losses, and improving power consumption ...

Problems solved by technology

[0003] The purpose of the present invention is to design an automatic user identification system for station areas to overcome the current problem of accurately grasping the user's station area and phase difference in order to judge which distribution transformer the user's electric energy meter belongs to and which phase of the distribution transformer to supply power in the intricate distribution lines. attribute, you need to go door-to-door with the receiving device to the location of each user meter, connect the receiving device to the power line, and collect the information including the transformer number and phase in the station area, in order to determine which transformer and which line the user meter belongs to. Very cumbersome and inefficient
