Power quality in distribution systems has been attracting an increasing interest during recent years. Research studies include the quality of voltage supply with respect to temporary interruptions, voltage dips, harmonics, and voltage flicker. Voltage flicker occurs when large industrial loads, such as electric arc furnaces, rolling mills, and pumps operate periodically in a weak power distribution system. The most commonly used device for compensation of voltage flicker is the Static Var Compensator (SVC). This paper presents the digital modelling and simulation of the voltage flicker phenomenon, which was observed in a 3 phase 415 V utility/customer distribution system.
