A New Control Strategy for Unified Power Quality Conditioner (UPQC) In Distribution Systems

2006 International Conference on Power System Technology, 2006
This paper presents a novel and easy to implement control strategy for unified power quality conditioner (UPQC). The control strategy of parallel active filter (PAF) is based on fourier transform theory, while the control circuit of series active filter (SAF) is based on positive sequence detection theory. Operating of PAF using this method compensates

Novel unified power quality conditioner (UPQC) of two DC links connected with resistor

2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA), 2016
This paper proposed a novel topology, which series inverter and shunt inverter both have capacitors in DC links, and connected by a resistor. And then establish mathematical model and control transfer function. At last compare the performance of traditional UPQC, separate UPQC and proposed UPQC in sag, harmonic and unbalance condition.

Unified Power Quality Conditioner (UPQC) research study on steady - state power flow

i-manager's Journal on Circuits and Systems
This paper presents a conceptual study of the Unified Power Quality Conditioner (UPQC) in mitigating voltage swell and sag occurrences on power distribution networks. A distinctive feature of UPQC is its capability to inject voltage within a range of 0° to 360° relative to the utility or Point of Common Coupling (PCC) voltage phase angle.
