Complex wavelet based control strategy for UPQC

2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010
This paper discusses the utilization of complex continuous wavelet transform based on B-spline function for reference voltages and currents extraction which are used for compensating power quality disturbances by using unified power quality conditioner. The major advantages of choosing B-spline function are the reduction of computation time and ease of

Comparison between UPQC, iUPQC and improved iUPQC

2017 Third International Conference on Sensing, Signal Processing and Security (ICSSS), 2017
In this paper a new proposal for the control of power quality is made by interline unified power quality conditioner (iUPQC) and comparison is shown with conventional unified power quality conditioner. Improved iUPQC controller provides additional regulation as STATCOM to grid voltage.

UPQC compensation strategy and design aimed at reducing losses

Industrial Electronics, 2002. ISIE 2002. Proceedings of the 2002 IEEE International Symposium on, 2002
After showing how the UPQC is able to-compensate for network voltage variations through different operating strategies, one such strategy is proposed whose aim is to limit the total losses of the device. An estimate was made of the extent of the losses of converters as a function of the DC section voltage and of the maximum injectable voltage from the ...

STATCOM and UPQC: options to enhance fault-ride-through capability of a fixed speed wind generator

6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012
The enhancement of fault-ride through (FRT) capability of a Fixed Speed Induction Generator (FSIG) with the help of a Unified Power Quality Conditioner (UPQC) and STATCOM are examined in this paper. The FRT performance of these equipments are evaluated and compared in accordance with Irish Grid Code requirement. A simulation study carried out on a 2 MW

Coordinated control strategy for UPQC and its verification

2006 IEEE Power Engineering Society General Meeting, 2006
This paper researches profoundly on the coordinated control of UPQC (unified power quality conditioner). By analyzing the radical reasons of coupling effect between UPQC series unit and shunt unit, a simple and practical coordinated control strategy for UPQC series unit and shunt unit is proposed, i.e.
