Low-voltage transformer area line-changing user topology identification edge calculation method based on HPLC carrier communication

Abstract

The invention discloses a low-voltage transformer area line-changing user topology identification edge calculation method based on HPLC carrier communication, and relates to the technical field of communication. A low-voltage transformer area HPLC carrier communication network is included and is composed of a CCO node and a plurality of STA nodes, the CCO node is configured in a concentrator, andthe STA nodes are branch box monitoring units and are configured in meter box monitoring units. Acquisition equipment of the low-voltage transformer area periodically exchanges acquisition data, the line relation of the installation position of the acquisition equipment can be identified based on the principle of synchronous fluctuation of acquisition data values of the same branch, the whole identification process is operated and verified by each edge equipment, and hardware equipment or master station operation does not need to be added. According to the method, the topological relation of the line-changing users in the low-voltage transformer area is recognized through an edge calculation method on the basis of original collection equipment, hardware cost and main station resources aresaved, and high accuracy and real-time performance are achieved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and specifically relates to an edge calculation method for identifying the topology of a low-voltage station area changing subscriber based on HPLC carrier communication. Background technique [0002] The electrical network topology of the distribution station area can help the power company quickly locate faulty equipment and improve the accuracy of collection. It is the cornerstone of the power company's power supply management. [0003] At present, the topology map of the distribution station area is drawn manually. Due to the large number of distribution station areas of the power company, the complicated electrical wiring, and the phenomenon of private construction, it is difficult to accurately grasp the electrical network topology of the distribution station area in time. At present, there are many topology recognition schemes in the market, but most of them choos...
