摘　　要：在传统的电表中,采样和数据处理模块用于计算测量值和电能,电压和电流电路直接或通过电磁变压器与电表连接,因而对数字电能计量系统进行研究有重要意义。本文通过与传统计量系统的比较,讨论了数字计量系统的应用结构和特点,给出了数字电能表的溯源模型,并通过一系列测试对数字电表的计量特性进行了检验研究,提出了有关检测项目、标准定量值追踪、转移方法和计量表分级,最后对误差结果进行可视化。验证系统性能表明,该方法可以有效地解决数字电表的验证和追溯问题。In traditional electricity meters,sampling and data processing modules are used to calculate measured values and electrical energy.The voltage and current circuits are connected to the electrical meter directly or through electromagnetic transformers,so it is of great significance to study digital energy measurement systems.This paper discusses the application structure and characteristics of the digital metering system by comparing with the traditional metering system,gives the traceability model of the digital electric energy meter,and examines and studies the metering characteristics of the digital electric meter through a series of tests,and proposes related tests.Project,standard quantitative value tracking,transfer method and meter classification are proposed,and finally the error result is visualized.The performance of the verification system shows that this method can effectively solve the verification and traceability problems of digital meters.
