摘要：

电能表是最为主要的电能计量装置,其质量直接决定了电能计量的准确性和可靠性。本文针对电子式电能表的寿命特点提出了一种分层分阶段的抽检方案,该方案将电能表全生命周期划分为两个阶段,依据实验室检定数据及现场运行校验结果设置合适的样本量及损坏率参数,对各个阶段进行动态分层抽样。综合了精度与成本因素,从根本上解决电能表质量跟踪成本高、实施难的现状,对将来电能表的选型决策和电能计量可靠性的提升有一定帮助。

Abstract: The quality of energy-meter, the most major energy metering device, determines the accuracy and reliability of energy measurement directly. A stratified and staged sampling method is proposed in this paper based on the life feature of electronic energy meters. The program divides the full life cycle of energy meters into two stages, and a stratified dynamical-sampling in each stage is proposed. The method integrates precision and cost factors and supplies a fundamental solution about high cost and difficult-implement in the quality trace of electronic energy meter. The result of the paper will play an important role in the selection of the energy meter and metering policy to enhance the reliability in the future.
