Batch identification device and identification method of low-voltage court household-transformer relationship

Abstract

The invention relates to a batch identification device and identification method of a low-voltage court household-transformer relationship. The batch identification device comprises a housing providedwith a three-phase four-wire joint. A controller and a power router are arranged in the housing and are connected. The power router is connected with a court three-phase four-wire unit through a three-phase four-wire connector and smart electric meter data of the user are obtained by the carrier. The controller includes a main control chip, a data acquisition module, an electric meter clock comparison module, a court identification and analysis module, a data storage module, and a wireless transmission module; the data acquisition module, the electric meter clock comparison module, the courtidentification and analysis module, the data storage module, and the wireless transmission module are connected with the main control chip by wires. The wireless transmission module is used for connecting a cloud server through a network. With the identification device, smart electric meters under the jurisdiction of all court transformers are analyzed and identified and then whether the smart electric meters of all users are connected correctly is identified rapidly, so that the management of the low-voltage court household-transformer relationship is realized well.

Description

Technical field [0001] The present invention relates to the technical field of identification of household change relations between stations and districts, in particular to a low-voltage station area household change relations batch recognition device and method. Background technique [0002] The household-to-station relationship refers to the power distribution relationship between the user's smart meter in the power supply area of ​​a transformer and the transformer in the power system, where the user's smart meter has a carrier module. The accuracy of the station-area-user-change relationship of the station-area management ledger is the basis of power system management, such as the division of the responsibility of the station-area manager, the maintenance and management of the PMS system ledger, meter reading management, operation and maintenance management, line loss statistics, and so on. It is the basis for the remote meter reading of the electricity information collection...

Problems solved by technology

The work efficiency of these two methods is relatively low, it takes a long time to complete, and the workload of the staff is heavy.

Moreover, the first method will also be affected by complex lines such as buried cables, and it is difficult for the staff to work. The second method is also vulnerable to the distance between the master detector and the extension detector, or the common zero line and common ground. Influenced by line, harmonic interference, etc., there is a phenomenon of inaccurate detection
