Abstract: The most important aspect for electrical engineering is power quality in recent year. Power quality problem is an event of abnormal voltage, current. The major problems here are the voltage sag and swell such a problems is now mitigated advanced power electronics technology. The dynamic voltage restorer is a power electronics based device that provides three phase controllable voltage source whose magnitude and angle assist to the source voltage during sag event to restore the load voltage to pre sag condition. The new configuration of DVR has been proposed using d-q-0 controllable technique. A control technique based on PID controller. The simulations are carried out using MATLAB/SIMULINK software.
Keywords: Dynamic Voltage Restorer, Voltage Source Converter, Power Quality, Voltage Sag and Swell, PID controller, etc.
