Abstract

Voltage sag and harmonics are major problems that affects the power quality thereby causes severe damage to customer equipments. These power quality problems can be mitigated efficiently using Dynamic Voltage Restorer (DVR). This paper proposed two control strategies namely PI controller and Fuzzy Logic Controller with dq0 transformation for DVR using MATLAB/SIMULINK. In these control strategies, Discrete PWM pulse generator along with Phase Lock Loop was used. Simulation results show the effectiveness of control strategies to mitigate the voltage sag and harmonics during various fault conditions.
