Voltage quality enhancement using unified power quality conditioner (UPQC)

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
Recently power quality has become more important issue. Day by day in industries and in distribution area power electronics based device are widely used and creates more power quality problems. The quality of the power is defective by certain reasons. This improvement of the quality of the power is seen e.g. as sag, swell, over voltages, under 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.

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 ...

Compensation of voltage flicker using Unified Power Quality Conditioner (UPQC)

2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2014
Voltage flicker, which is a repetitive voltage magnitude change of low frequency, is one of the power quality problems. The problem is aggravated with the use of non-linear load. The paper presents the use of a Unified Power Quality Conditioner (UPQC) as a solution to voltage flicker. A simple control technique is proposed to control UPQC.

A novel control strategy for unified power quality conditioner (UPQC)

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
This paper presents a novel and easy to implement control strategy for unified power quality conditioner (UPQC). This control strategy is usable in three-phase three-wire utilities. The control strategy of parallel active filter (PAF) is based on combination of extended p-q theory and instantaneous symmetrical components theory while the control ...
