Abstract :
Flicker, caused by large fluctuating loads as arc furnace, is one of the power quality problems that include
interruptions, voltage sags and dips, harmonics. The state of the art technology to reduce flicker is shunt compensation
using Static Var Compensator with thyristors. However, this kind of technology has an intrinsic limited flicker
mitigation capability. Traditionally, flicker is mainly due to reactive power fluctuation. However, Flicker generation is
more complicated and in the paper, drop voltage and shunt compensation methods are described step by step to explain
flicker. Simulations of arc furnace installation with shunt compensation device using Voltage Source Converter or
STATCOM with its control are presented. Multilevel structure simulation is shown. Reduction of PST versus shunt
compensation methods is shown.
