    Abstract

    With the continuous outstanding development of electronic devices, the power quality problems have been remarked as a great growing concern, whereas voltage sag and swell problem are the most frequently occurring and detrimental power quality problems. Therefore, the purpose of this study was to mitigate voltage sag and swell problem with UPQC using proposed adaptive multi converter (AMC). The proposed device was implemented during generating voltage sag and swell problem in electronic appliance. The quick response view of AMC-UPQC power distribution system with regard to reactive power was illustrated at 0.02 sec. The results showed that the developed converter was capable to compensate the voltage sag problem by 99.72%, 96.24%, 94.45% and the voltage swell by 93.33%, 83.33%, 77.27% at 1phase, 2-phase, and 3-phase, respectively. Besides, it can combat the dynamic load significantly, 87.06 % and 75 % at voltage sag and swell condition respectively. The unique feature of AMC-UPQC is the rate of potentiality of voltage sag /swell mitigation notably higher compared to conventional UPQC as adaptive multi converter responses on account of reactive power quickly and timely. As a result, the developed power distribution system was substantiated as a proficient compensator for the reactive power requirement of the load and in future it can be used as a fancy power distribution system for the protection of dynamic load. Key words : Sag, swell, AMC, UPQC, reactive power.
