Unit Vectors of SRF Control Algorithm based DVR for Power Quality Improvement

Today India trends towards the Research Development as the Research leads to make the country developed. In all the several Disciplines in Research Power System shows the great embark in development. DVR is used for compensation of Voltage sensible problems like swell sag etc. The Unit Vectors of SRF control algorithm used for the compensator plays a major role in power quality improvement. Unit Vectors of SRF Synchronous Reference Theory is considered as control algorithm for the compensator. Generally, control algorithm generates the reference signal. In the conventional SRF control algorithm the reference is generated with the help of Phased Locked Loops but it consumes more time. Hence this paper proposed the unit vectors for the generation of references for the load voltage. Hence the generated reference signal is compared with load voltages. Thus, obtained error is converted into the pulses with the help of a PWM converter and is given to DVR. Form the pulses DVR inject this error into the system and compensate the power quality problems. The projected DVR is simulated in Matlab 2012a and the results are validated by simulation results.
