Conceptual Study of Unified Power Quality Conditioner (UPQC)

2006 IEEE International Symposium on Industrial Electronics, 2006
This paper deals with conceptual study of unified power quality conditioner (UPQC) during voltage sag and swell on the power distribution network. One of the peculiarities of UPQC is that it can inject voltage from 0deg to 360deg. Based on this injected voltage phase angle with respect to the utility or PCC voltage phase angle, UPQC can absorb or ...

Review on Unified Power Quality Conditioner (UPQC) to mitigate power quality problems

2021 2nd Global Conference for Advancement in Technology (GCAT), 2021
For the normal working of the electrical apparatus customers want an uninterrupted flow of sinusoidal voltage and current of continual magnitude and frequency at the AC mains. Although the generated voltage at power plants is almost sinusoidal but our current power system has wide range of electrical apparatus some of which are non-linear in nature ...

A simple new control technique for unified power quality conditioner (UPQC)

2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat. No.04EX951), 2005
It is expected that, in future, utility service providers will enforce more strict power factor and harmonic standards. Therefore, efforts are being made so that power electronic system or any other load drawing reactive volt-amperes is made to appear as linear load drawing current in-phase with the utility voltage.

A single phase unified power quality conditioner (UPQC)

2016 IEEE International Conference on Power System Technology (POWERCON), 2016
This paper proposes a simple power circuit topology for single phase unified power quality conditioner (UPQC). The number of power circuit switches of conventional single-phase UPQC is reduced to half and hence it has resulted in considerable reduction of cost, weight, volume, protection circuits, power losses and control circuit complexity.
