Harmonic Mitigation in Distribution System by using Passive Filters

The advent of power electronics and computerized equipment in recent decades has brought enhanced efficiency and improved system but at the same time also created harmonics and waveform distortion to the power system network. Due to the growing use of nonlinear load equipment and new technologies in buildings, harmonic currents and voltages generated in distribution systems pose a new problem for electrical engineers. This is a serious problem when power quality is a prime concern. Harmonics are the main types of power quality problem that are very common to the power system containing electric arc furnace EAF . Electric arc furnace EAFs are widely used in steelmaking and in melting of nonferrous metals. In this paper, EAF is presented guide lines for the accurate evaluation of harmonics generated in No. 3 Steel Mill, Ywama, Yangon. Passive filters have been most commonly used to limit the flow of harmonic currents in distribution systems. Their performance is limited to a few harmonics, and they can introduce resonance in the power system.
