Abstract

Quality of the output power delivered from the utilities has become a major concern of the modern industries for the last decade. These power quality associated problems are voltage sag, surge, flicker, voltage imbalance, interruptions and harmonic problems. One such reliable customer power device used to address the voltage sag problem is the Dynamic Voltage Restorer (DVR). It is a series connected custom power device, which is considered to be a cost effective alternative when compared with other commercially available voltage sag compensation devices. The main function of the DVR is to monitor the load voltage waveform constantly and if any sag occurs, the balance voltage is injected to the load voltage. This project intend to investigate the performance of DVR to mitigate the occurrences of voltage sags has been presented. Two control techniques; PI and Fuzzy Logic (FL) have been proposed to control the injection voltage. The performances of DVR based on these two control techniques have been analyzed using MATLAB/SIMULINK simulation software and has shown reliable results. The result shows that FL controller give a better performance compares to PI controller. Apart from those two control techniques, other factors that also can affect the performance and capability of DVR are presented as well.
