Comparing series and parallel hybrid filters for harmonic reduction in hot strip mill with cycloconverters

This paper presents a comparison between two hybrid filtering approaches applied for harmonic filtering in a hot strip mill. The study is carried out through digital simulation. The relevant waveforms of the system are analyzed mainly concerning their harmonic spectrum, allowing the performance analysis of each filtering system in the electrical system power quality. The structures behavior are also evaluated regarding the reduction of the current in the system of passive filtering, front to a possible expansion of the system. The obtained results show that the best solution for harmonic reduction is the active-passive series structure.
