Impact of the number of angles and levels on harmonic mitigation in multilevel converters

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
This paper investigates about the impact of the number of levels and of the corresponding modulations angles on the mitigation of harmonics in cascaded H-bridge multilevel inverters. A mathematical model to reduce Nth odd harmonics from the output voltage of a multilevel converter is represented as a constrained optimization problem.

Power Improvement by Mitigating the Harmonic Distortions

Quaid-e-Awam University Research Journal of Engineering, Science & Technology
The study of harmonics in power systems (PS) is very crucial and mitigation of harmonic distortions is one of the main issues these days. Harmonics are distortions in the waveform of a power system with a frequency that is an integral multiple of the frequency variable of the fundamental power line.

A Review and Critique of Advances in the Mitigation of Harmonics

ARID ZONE JOURNAL OF ENGINEERING, TECHNOLOGY AND ENVIRONMENT
In electrical power distribution systems, harmonics has always been a major concern as it can adversely affects the performance of the connected loads when tolerable or recommended standard limits are exceeded. There have been consistent and considerable efforts to study the sources, generation and control of harmonics over the years.

Active power filters for harmonics mitigation

This technical note presents the principles and control strategies of shunt active power filters (APF) designed for harmonic current mitigation in electrical grids. It discusses the identification of harmonic components generated by non-linear loads, reference current generation methods, and the design of high-bandwidth current controllers. Finally, it

Harmonics mitigation of industrial power system using harmonic blocking compensators

2015
This paper presents a passive harmonic blocking compensator (PHBC) for harmonic suppression and reactive power compensation in distribution systems. PHBC composed of a line series filter tuned to the fundamental frequency and a shunt passive filter. FORTRAN Feasible Sequential Quadratic Programming (FFSQP) is used as an optimization tool to find the ...
