Improvement of Power Quality Using Repetitive Controller for Dynamic Voltage Restorer
Lalitha V, Vindhya Smitha K
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. This paper discusses a controller based on repetitive control for a dynamic voltage restorer (DVR) to compensate voltage sag, harmonic voltages and voltage imbalances. Repetitive control can achieve zero steady-state error. The simulation is carried out in the MATLAB/SIMULINK environment which shows reliable results.
