Abstract :
The proposed Dynamic Voltage Restorer(DVR) is used to mitigate voltage sag, swell, harmonics and unbalance in the supply voltage. This paper presents Instantaneous Reactive Power Theory(IRPT) Control Algorithm for three-leg Voltage Source Converter (VSC) based DVR in the three-phase distribution system. The proposed DVR injects voltages in series with source voltage to regulate rated voltage. The gating signals for three-leg VSC based DVR are extracted from reference load voltages. The proposed IRPT Control Algorithm based DVR results are validated through computer simulation studies using MATLAB/SIMULINK.
