A New Coordinated Operation Strategy for Unified Power Quality Conditioner (UPQC)

2018 IEEE 27th International Symposium on Industrial Electronics (ISIE), 2018
This paper proposes a new coordinated operation strategy to improve the low utilization rate of series inverter in traditional unified power quality conditioner (UPQC), and to fully optimize the total capacity of UPQC. When source voltage is in the normal range, the series inverter compensates part of reactive power by reducing the source power factor ...

A Novel Hybrid Unified Power Quality Conditioner (UPQC) for Medium-Voltage Power Grid

Advanced Materials Research, 2013
This paper proposed a three-phase three wire UPQC (hybrid UPQC). The topology is novel which consists of a series and a hybrid shunt filters. The unique topology can reduce the capacity of power devices in the hybrid UPQC when compensating source harmonic currents. In this paper a detailed design about the main circuit is presented.

A new reference waveform estimation strategy for unified power quality conditioner (UPQC)

2010 IEEE International Energy Conference, 2010
In this paper, a new reference waveform estimation strategy based on an adaptive notch filter (ANF) is proposed for unified power quality conditioner (UPQC). Two coupled ANFs are used to generate the reference waveforms for shunt and series components of UPQC. Mathematical properties of proposed algorithm are presented in detail.

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.
