Influence of Voltage Variation on the Measurement of Total Harmonic Distortion (THD) by AMI Smart Electricity Meters

2021 13th International Conference on Measurement, 2021
Power quality parameters specified in standards IEC 61000–4–30 and EN 50160 are used to power quality evaluation in the power grid. These parameters are, among others higher harmonics and the Total Harmonic Distortion (THD). Measurement and recording of power quality parameters is carried out mainly by power quality analyzers.

Total Harmonic Distortion (THD) Estimation Technique Based on Power Concept for Smart Power Meters

2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2019
This paper proposes a time-domain total harmonic distortion (THD) estimation technique for smart power meters with significant reduction of calculation steps and high accuracy. In addition, the potential advantage of the proposed THD estimation technique is that the active and reactive power components obtained during the calculation can be further ...
