Abstract: Series compensators are implemented in power system to overcome the power quality issues like voltage dip (sag) and voltage swell. Series compensators such as Dynamic Voltage Restorer have demonstrated their effectiveness in enhancement of power quality. The control techniques for these devices underwent the progressive changes as per industry needs. Control techniques can be majorly classified as frequency domain (s-domain) and time-domain techniques. In the time-domain algorithm reference signal generation is important step for successful implementation of algorithm. In this paper the two reference generation methods namely Synchronous Reference Frame (SRF) method and Unit Vector template (UVT) method are analyzed and compared for their suitability considerations.
Keywords: Phase lock loop, Power quality Series compensator, Synchronous Reference Frame, Unit Vector template
