Abstract

The invention discloses an electric meter transformer area identification method based on voltage data. The method comprises the steps that a concentrator (CCO) sends a district identification commandto a whole-network intelligent electric meter through a broadband carrier communication system; the intelligent electric meter on the concentrator side and the intelligent electric meter to be subjected to transformer area identification start to acquire respective voltage data in a specified time period according to command requirements; a communication module in the intelligent electric meter reports acquired voltage data to the CCO through the broadband carrier communication system; after receiving the data, the CCO calculates the voltage data similarity between any two in-phase ammeters in combination with the phase information of the electric meters and the routing information between the electric meters; in order to improve the identification precision, the CCO carries out voltage data collection and similarity calculation for many times in different time periods; and after the collection frequency reaches the specified requirement, the CCO comprehensively judges the transformerarea affiliation relationship of all the intelligent electric meters in the transformer area network based on the data.

Description

technical field [0001] The present application relates to the technical field of electricity consumption information collection of low-voltage power grids, in particular to a method for identifying electric meter stations based on voltage data. Background technique [0002] In the power consumption information collection system of the low-voltage power grid, the station area refers to the power supply range of a transformer, and the power consumption management department also uses the station area as the basic unit for network management and function maintenance. The smart meter is not only a metering device for the amount of electricity consumed by users, but also has the function of collecting key parameters of electricity consumption by various users. Very important for management. The current electricity consumption information collection system generally sends the electricity meter file to the concentrator through the master station, and then performs cost measurement...
