This investigation develops an enhanced method for estimating the voltage flicker of the electric arc furnace (EAF). The method not only considers the reactive power variation but also the active power variation in calculating the estimated ΔV10 value of EAF. This study also considers field measurements of ac and dc EAFs. The results reveal that the estimated ΔV10 value is significantly smaller than the observed value. The conventional way of estimating ΔV10 is ineffective. The survey results demonstrate that variations of active power and reactive power of EAFs are strongly alike. Meanwhile, an ΔV10 estimate must account for the effect of active power variation. However, this study proposes a maximum complex apparent power fluctuation method (MCAPFM) that can yield a more accurate ΔV10 estimation than the conventional method.
