ABSTRACT:
In this study a method is proposed in order to improve
the voltage compensation performance of Dynamic Voltage Restorer by using Self
Tuning Filter. The proposed control method gives an adequate voltage
compensating even for 50% voltage sag and distorted voltage conditions. The
proposed DVR control method is modeled using MATLAB/SIMULINK and tested both in
off-line and real-time environment. Results are then presented as a
verification of the proposed method.

CONCLUSION:
This
paper shows the effectiveness of implementing STF in the traditional control
method of DVR to compensate the distorted and unbalanced grid voltage condition
as well as sudden drop or increase in grid voltage. Performance of the improved
method is tested both in off-line and real-time mode. Results show that the
proposed method can significantly improve the performance of the DVR and thus the
load does not sense any kind of grid voltage disturbances.
Moreover,
the grid voltage harmonics are effectively suppressed on the load terminal.
