Remote online verification method for intelligent electric energy meter

Abstract

The invention discloses a remote online verification method for an intelligent electric energy meter, which relates to the technical field of electric energy metering. The method comprises the following steps of S1, setting an electric energy meter end interface and a reserved verification interface on the intelligent electric energy meter, S2, connecting one end of acquisition equipment with an intelligent electric energy meter end interface, connecting the other end of the acquisition equipment with a merging unit used for sampling current and voltage values of the intelligent electric energy meter, connecting one end of the acquisition equipment with the reserved verification interface, and connecting the other end of the acquisition equipment with a calibrator, and S3, enabling the acquisition equipment to send a data request to the calibrator and the intelligent electric energy meter. The online verification of the intelligent electric energy meter is realized, the verification data of the tested electric energy meter can be managed and analyzed by using the remote server, the remote monitoring of the operation state of the electric energy meter is realized, the lean management of the electric energy meter is improved, and the social benefit is good.

Description

technical field [0001] The invention relates to the technical field of electric energy metering, in particular to a remote online calibration method for an intelligent electric energy meter. Background technique [0002] The development of electricity is related to the resource allocation of the whole society. Therefore, the reform and progress of the electricity market can mobilize all aspects of society to make reasonable investment, reduce electricity prices, and reduce waste, thereby bringing huge economic benefits to the entire society. The reform of the electricity market has great impact on Electric energy measurement puts forward new requirements, such as power quality and reactive power measurement, remote automatic meter reading and calibration, etc. These new requirements make the power departments of various countries realize the shortcomings of traditional inductive energy meters and management methods, which greatly promotes The development of new electric ener...

Problems solved by technology

[0003] Most of the traditional existing electric energy meters are carried out by professionals to the site for periodic inspections. The cycle is long, and it is difficult to find out the measurement failures that occur between the two inspections in time, which has a great impact on billing management. The standard The meter is used in the laboratory environment. In the environment of strong electromagnetic interference, temperature, humidity and other conditions in the substation, the accuracy and stability of the standard are affected. For this reason, a remote online calibration of smart energy meters is proposed. The method has solved the above problems
