摘要

摘要本文介绍了用远程无创技术估算电能表校正因子的误差分析。阐述了一种基于被测仪表和参考仪表功耗曲线中同步检测功率阶跃的CF估计方法。电表CF估计不确定度对功率阶跃幅度、每个观测间隔的功率阶跃数量以及由一个参考电表监测的测试电表数量的依赖性是近似的。合成的消费者有功功率分布用于获得由这些近似方程拟合的训练数据点。

Estimation of Energy Meter Accuracy using Remote Non-invasive Observation

Abstract This paper presents an error analysis of the estimation of energy meter correction factor (CF) using a remote non-invasive technique. A method of the CF estimation based on the comparison of synchronously detected power steps in power consumption profiles of meter under test and reference meter is elaborated. The dependence of meter CF estimation uncertainty upon the magnitude of power steps, the number of power steps per observation interval, and the number of meters under test monitored by one reference meter is approximated. The synthesized consumer active power profiles are used to obtain training data points that are fit by these approximating equations.
