Electric energy meter online fault detection method and system based on electric power broadband carrier communication

Abstract

The invention provides an electric energy meter online fault detection method and system based on electric power broadband carrier communication, and belongs to the field of electric power broadband carrier meter reading. The online fault detection method comprises the following steps of: finding a neighbor electric energy meter on a power line according to the carrier communication signal strength; establishing a mutual detection relation with the neighbor electric energy meter; acquiring electric energy parameters of the neighbor electric energy meter regularly; and comparing the obtained electric energy parameters of the neighbor electric energy meter with own electric energy parameters, and judging whether the electric energy meter has metering faults or not. The invention also provides a system for realizing the online fault detection method. The method has the advantages that: faults can be found earlier and more timely, maintenance can be conducted in time, power utilization disputes are reduced, the user satisfaction degree is improved, negative errors are found in time, losses of electric power companies can be reduced, and the line loss rate is reduced.

Description

Technical field[0001]The present invention relates to the field of power broadband carrier meter reading, and more particularly to a power meter online fault detection method and system based on a power broadband carrier communication.Background technique[0002]Energy consumption is closely related to us, especially the use of power energy, and the energy meter as the meter of electric energy as a power meter, and the accuracy of its work is directly affected by our safety electricity and power grid. management. The power meter has long been operating in the grid. The stability of its work is not able to master the current technology in real time. Generally, users cannot use electricity complaints to the grid company customer service or electrical data is abnormal. Customer service, arrangement personnel to check the inspection of the detection center test to find that it is caused by the user to produce cost disputes. Second, the energy meter measurement fault causes a small energy ...

Problems solved by technology

[0004] The power carrier meter reading system is currently used as a communication module, reading the event data and electricity data of the energy meter cannot judge the accuracy of the energy meter measurement data

Relying on the zero-crossing detection circuit of the broadband carrier module to realize station area identification and phase line identification, it is also impossible to judge the accuracy of the energy meter measurement data
