Problems solved by technology

[0003] At present, the user's station area identification mainly relies on the power carrier technology, which needs to send the carrier signal from the concentrator, and then connect the user terminal to the measurement tool for measurement. Not only the workload is very heavy, but also it is easily interfered by electromagnetic signals

Abstract

The invention relates to an automatic identification method for an electric energy meter platform area, which belongs to the application field of electric parameter measurement of a distribution network. Firstly, a voltage loss model is established based on the accurate data of the existing station area. Then, based on the voltage loss model and user-end data, the voltage of the master meter in the area is estimated. Finally, the correlation analysis between the estimated voltage and the actual voltage is carried out, and the station area to which the user's electric energy meter belongs is comprehensively determined, and the correlation coefficient between the two is given, so as to improve the management ability of the power grid and promote the healthy and stable operation of the power grid.

Description

technical field [0001] The invention belongs to the application field of electric parameter measurement of a distribution network, and relates to an automatic identification method for an electric energy meter platform area. Background technique [0002] In the daily management of the distribution network by the power company, issues related to the station area to which the user's electric energy meter belongs are often involved, such as remote fee control, clock timing, three-phase power balance, phase sequence control, and line loss calculation, etc. . Accurately identifying the station area to which the user's energy meter belongs can realize refined marketing and effectively reduce consumption and loss. [0003] At present, the user's station area identification mainly relies on the power carrier technology, which needs to send the carrier signal from the concentrator, and then connect the user terminal to the measurement tool for measurement. Not only is the workload v...
