Fuzzy Controller based Topologies of NS-UPQC and B4-UPQC
2020 IEEE International Conference on Advent Trends in Multidisciplinary Research and Innovation (ICATMRI), 2020In this paper the controller which have been used to find Kp and Ki values are different than the conventional one.Basically fuzzy controller have been used in both the layouts. NS type layout utilizes just nine IGBT switches for both the cycle of DVR and DSTATCOM.

Comparative performance analysis of UPQC and Open UPQC
2015 Annual IEEE India Conference (INDICON), 2015In recent days, the quality of power has become more important to the most of the customer load. The unified power quality conditioner (UPQC) is the ultimate solution to provide the quality of power irrespective of the type of power quality problems. The UPQC can improve the quality of power for all end users, but it will not provide the power quality ...

10th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.02EX630), 2004
In this paper an analysis of the line interactive device UPQC (unified power quality conditioner) from a reliability point of view is carried out. A brief description of its topology points out the components constituting it, such as the static transfer switch, the converters, the energy storage unit and the input static switch.

Performance evaluation of R-UPQC and L-UPQC based on a novel voltage detection algorithm
2012 IEEE Symposium on Industrial Electronics and Applications, 2012This paper proposes a new method to detect voltage imperfections such as balanced/unbalanced voltage sag/swell, voltage flicker, and voltage disturbance in a single or three-phase electrical systems with excellent performance characteristics. The proposed method is based on single-phase synchronous d-q reference frame transformation. In contrast to the

Operating Region of Single-Phase UPQCs
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006The stationary analysis of a single-phase unified power quality conditioner is introduced. The decomposition of a single-phase waveform into a sum of sine and cosine functions gives a representation of the original signals and at the same time allows to find the operating region of the system.

A Novel UPQC based on variable impedance
2021 Power System and Green Energy Conference (PSGEC), 2021A unified power quality controller based on a magnetic flux control tunable reactor is proposed. The magnetic flux control tunable reactor is composed of a voltage source inverter (VSI) and a transformer with an air gap. The power quality controller is divided into two parts: the harmonic open circuit part is connected in series in the system, and the ...

A Novel Control Strategy for UPQC
2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005UPQC is the powerful tool to settle the power quality problem. This paper presents a novel control strategy of UPQC. It can be used in the system that voltage and current are unbalanced or/and with harmonics. Only the voltages and the currents measured are used in the control, it avoids the transformation like Park transformation of dq0 theory which is

Traditional schemes of UPQC and OPEN UPQC are proposed in literature to solve both the voltage quality problem of the load and the current quality problem of the grid. However, the traditional UPQC is not flexible when configured to compensate an industrial park if not all loads are sensitive. The previously proposed OPEN UPQC scheme has the advantages
