Abstract

The present invention proposes a precise control system and method for online error calibration of smart electric energy meters, considering that in the process of error measurement, calibration and correction of intelligent electric energy meters, the errors of intelligent electric energy meters may come from such as measurement errors, creep Performance affects aspects such as light load error, sampling error of sampling circuit, and attribution error. Through the normalized configuration of ternary calibration information, a multi-angle integrated intelligent electric energy meter online error calibration precision control system and its method are realized. The method avoids technical problems such as lack of feedback parameters and imperfect statistics in the prior art for smart electric energy meter error verification.

Description

technical field [0001] The invention belongs to the field of information technology of a new generation of intelligent internet of things, and in particular relates to a precise control system and method for online error verification of an intelligent electric energy meter. Background technique [0002] As an important node component of the power grid structure, the smart energy meter has replaced the traditional energy meter and has become the main node for power consumption observation of systems or enterprises and individual users, as well as an important power grid monitoring function terminal. [0003] Smart meters are an important part of modern power systems. Whether it is household meters or industrial, commercial, mechanical, and electric power meters, more and more smart meters appear and use. Unlike traditional meters, smart meters include users. Functions such as terminal control, two-way multi-rate metering, and data transmission are the embodiment of the develo...
