An AC arc furnace is an unbalanced, nonlinear and time varying load, which can cause many problems to power system quality. Different studies on arc furnaces harmonics analysis can be found in the bibliography on the topic; however, it is very difficult obtain an exact model that takes into account all the parameters that have influence on the process, therefore it is necessary to take measurements...
This paper presents a novel active current shaper, called hereinafter a load compensator (LSTATCOM), for a 12-pulse diode converter. The LSTATCOM injects compensation current through a split winding interphase reactor connected on DC bus of the 12-pulse converter. It is desired that the LSTATCOM provides sinusoidal shaping of the source currents for an output load varying over a wide range. The proposed...
