Abstract

The invention discloses a remote source tracing method and system of a digital electric energy standard meter based on a quantum technology. The method comprises the steps of: obtaining standard electric energy data generated after a pre-set power source is subjected to source tracing through alternating-current quantum voltage; sending the obtained standard electric energy data to a metering client side comprising a measured digital electric energy meter through a communication network; obtaining output electric energy detection result data when the measured digital electric energy meter in the metering client side responds to the standard electric energy data; and, performing electric quantity comparison based on the standard electric energy data and the electric energy detection resultdata, and calculating the electric quantity error between the two, namely the metering error of the measured digital electric energy meter. According to the remote tracing method and system of the digital electric energy meter based on the quantum technology in the invention, an electric energy signal subjected to source tracing through the quantum voltage is used as a standard electric energy signal; remote source tracing of the digital electric energy meter is realized; source tracing is efficient and reliable; and remote inspection can be avoided.

Description

technical field [0001] The invention relates to a digital electric energy meter traceability detection technology in the field of metering, in particular to a remote traceability method and system for a digital electric energy meter based on quantum technology. Background technique [0002] In a smart substation, the electric energy metering device is a digital electric energy metering device composed of an electronic transformer, a merging unit and a digital electric energy meter. Among them, the electronic transformer converts the high voltage and high current on the transmission line into a digital signal or a small analog signal according to a certain proportional relationship, and the merging unit is used as a digital interface between the acquisition and measurement of electrical parameters such as voltage and current. The digital signals or analog small signals output by multiple electronic transformers are time-related combined, and then the combined value of the dig...
