Abstract: The line-commutated converters cause significant harmonic distortions in electrical power systems. They can operate as a six-pulse converter or configured in parallel arrangement for high-pulse operation; twelve pulse converters are usually used for DC arc furnaces. The DC arc furnaces can cause time varying power quality disturbances in the feeding network, mainly waveform distortion and voltage fluctuations. In this paper the problem of the waveform distortion assessment of these important disturbing loads is taken into account. The study is performed using computer simulations based on Power System Blockset, that is a tool of Matlab®, and using a chaos-based model for simulating the dc arc.
