POWER QUALITY IMPROVEMENT BY MITIGATION OF VOLTAGE SAG WITH DVR USING SVPWM TECHNIQUE
Main Article Content
Abstract
In last decade, research hasbeen carried out to address the problems associated with power quality improvement issues.The power quality is affected mainly due to the sensitive loads which results in voltage sag and voltage swells.It is necessary to investigate the suitable methodsformitigation of voltage sags.From the wide range of mitigation methods, the selected one has to be observed for the effect on the characteristics.Authors have carried out the study and implementationof mitigation method to address the stated problem.In this paper, authors have implementedDynamicVoltage Restorer (DVR) based on application of SpaceVector Pulse Width Modulation (SVPWM).The implemented model gives remarkable results and mitigation of voltage sag is achieved.
