SIMULATION AND ANALYSIS OF UNIFIED POWER QUALITY CONDITIONER FOR POWER QUALITY IMPROVEMENT USING UVTG

Ravi Dave

Abstract :

<p>&nbsp;Nowadays, the quality of electric power supply has improved a lot by the use of power electronics based equipments. This power electronics based equipments plays a greater role in eradicating the power quality problems such as Harmonic Distortion, Current Transient etc. But the conventional power quality based equipment does not give 100% output in power quality. Therefore it is necessary for the power engineers to develop a dynamic and most advanced solution to these power quality problems. So they find a most promising solution to this problem is Unified Power Quality Conditioner (UPQC). UPQC deals with both load current and supply voltage imperfection. The UPQC is a combination of series and shunt active power filters connected in cascade via a common DC link capacitor. The series APF is mainly used for compensate voltage related problems like Voltage harmonics distortion, Voltage Sag/Swell, Interruption. Whereas, the shunt APF is used for current related problems like Current harmonics distortion, Transient Current. The UPQC is working with Unit Vector Template Generation based control technique. The simulation results of a three-phase Unified Power Quality Conditioner (UPQC) using Unit Vector Template Generation based control techniques have been carried to compensate voltage and Current related Problem.</p>
