Abstract: Today Power Quality is a prime concern due to the introduction of high-tech devices. Power quality problem is natural event such as non-sinusoidal voltage, current or frequency whose outcome is failure of end use equipments. Usually, Voltage Perturbation is a major power quality problem. Voltage Perturbation is due to use of much electronic equipment in industrial distribution system. The voltage perturbation is such as voltage sags, swells, harmonics, Unbalance & Flickers. To figure out these difficulties, custom power devices are used. Among them the DVR (Dynamic Voltage Restorer) is the most efficient & effective in power distribution. DVR gives fast dynamic response to the perturbation. In this thesis modeling of DVR for voltage compensation is done by using MATLAB software is presented in which we use PI Controller and Discrete PWM Generator.
Keywords: Dynamic Voltage Restorer, voltage sags/swells, VSI, Phase Sequence Analyzer.
