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.

Performance analysis of a Nonlinear system with reduced Total Harmonic Distortion (THD) based Hysteresis Current Controller (HCC) using 3 phase DC/AC

2020 International Conference on Computational Intelligence for Smart Power System and Sustainable Energy (CISPSSE), 2020
A nonlinear system determines the quality of power under closed and open control. An issue with power is overcome by a three-phase DC/AC embedded DC/DC ZETA converter with proposed Hysteresis Current Controller (HCC). In this proposed system, personal computers are operated in order to record harmonic generation.

Impact of Grid Connected Photovoltaic System on Total Harmonics Distortion (THD) of Low Voltage Distribution Network: A Case Study

2018 Twentieth International Middle East Power Systems Conference (MEPCON), 2018
Integrating renewable energy resources especially photovoltaic systems with microgrids has become an unavoidable choice for most countries and in Egypt the government has this ambition to reach a percentage of 20% of the total national electricity generation from solar energy. Which in turn bring some challenge to the electrical utility operator.

Control and reduction of terminal voltage total harmonic distortion (THD) in a hybrid series active and parallel passive filter system

Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002
A simple and cost-effective solution to reduce the passive filter terminal voltage total harmonic distortion (THD) is outlined. A modified synchronous reference frame (SRF) based controller for the series active filter allows injection of a controlled percentage of the higher harmonic load currents into the supply, in compliance with the IEEE 519 ...

Design and Implementation of SVPWM Inverter to Reduce Total Harmonic Distortion (THD) on Three Phase Induction Motor Speed Regulation Using Constant V/F

2020 3rd International Seminar on Research of Information Technology and Intelligent Systems (ISRITI), 2020
The electric motor has replaced motor fuel as the main mover of the equipment. One of them is the use of a three-phase induction motor in the industrial sector. Equipment in an industry requires many speed controllers in operation. The induction motor speed can be changed by changing the number of poles, changing the stator voltage, and changing the ...

ANALISIS TOTAL HARMONIC DISTORTION ( THD % ) ARUS SECARA TEKNIS PADA GARDU DISTRIBUSI POLITEKNIK NEGERI MALANG

2018
With the standard IEEE 519-1992 Refers harmonics can be identified by comparing the measurement results with those standards so it can be known whether a certain point (point of common coupling) are harmonics. Where the percentage of allowable voltage below 69 kV attached to harmonic voltage is 5% while for Total Harmonic Distortion (THD%)current is 15%
