Summary:Due to harmonic distortion, voltage dips, voltage swells, and frequency variations, power quality is the most crucial problem in the distribution system. A device which is connected in series known as Dynamic voltage Restorer is smaller in size, has a higher energy storage capacity, and is more power-efficient than other specialized power devices, is used in this paper to compensate for voltage dips. In this study, the voltage drop at various dipped values is balanced using space vector pulse width modulation approach. Employing Fast Fourier Transform analysis, the Total harmonic Distortion values are also computed and analyzed for two different conditions that is having filter unit and absence of filter respectively is utilized in the DVR section. The analysis shows the improvement in the Total harmonic Distortion by incorporating the filter section is also assessed.
