Transformer area identification method of intelligent ammeter

Abstract

Disclosed is a transformer area identification method of an intelligent electric meter which comprises the steps that a management terminal issues an intelligent electric meter transformer area identification command to a concentrator; a concentrator performs clock correction on the intelligent electric meters in the identification range; the concentrator issues a transformer area identificationcommand to the intelligent electric meters in the identification range, and requires the related intelligent electric meters to acquire power frequency period zero-crossing data in a specified time window and report the power frequency period zero-crossing data; after receiving the command issued by the concentrator, an intelligent electric meters in the identification range collect and report power frequency period zero-crossing data of the intelligent electric meters in a specified time window, and the concentrator collects and stores the power frequency period zero-crossing data of the intelligent electric meters in the specified time window; and after the concentrator receives the data reported by the to-be-identified intelligent electric meters, data similarity analysis is made on the data reported by the to-be-identified intelligent electric meters and the concentrator in-phase acquisition data one by one to obtain a transformer area identification result. Court identification is carried out based on power frequency period (zero-crossing) data, information of original data is fully utilized, and the identification accuracy is high.

Description

technical field [0001] The invention relates to a power supply station area identification technology, in particular to a household variable relationship / station area identification method. Background technique [0002] In the low-voltage power line power consumption information collection system, the station area refers to the power supply range or area of ​​a certain transformer, and is an important division for the power management department to finely manage low-voltage users. At present, most power companies in my country have adopted the method of sub-regional management for low-voltage power users, and use the sub-region as the basic unit for marketing management, which can better monitor power consumption and prevent power theft. As the core equipment of power management, the smart meter is very important to correctly identify the affiliation relationship of its station area. [0003] At present, there are mainly the following methods for station area identification...

Problems solved by technology

Although this method reduces the manual workload, the accuracy of the recognition results is not high due to factors such as signal crosstalk.

3) The low-voltage station area identification equipment based on FSK carrier and pulse current technology is used for station area identification, but the function of this type of equipment is relatively single, the test accuracy still needs to be improved, and there are problems such as large equipment size and inconvenient use
