An integrated model for the study of flicker compensation in electrical networks

This paper presents an integrated model for the simulation of the voltage flicker introduced to a power system due to an arc furnace operation. The model was developed for power system planning purpose in the ATP computational environment. It can be adjusted to the desired operation conditions so as to correctly simulate the furnace operation stages (melting or refining stage) and the expected furnace's degree of flicker severity, for each particular arc furnace and power system combination. Chua's oscillator circuit is used to achieve the chaotic nature behavior of the arc voltage and a Static Var Compensator (SVC) is used for flicker compensation. Modeling and simulation of the full package, including an IEC flickermeter used to evaluate flicker severity, are presented.
