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 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 unified power quality conditioner (UPQC) for simultaneous voltage and current compensation

Electric Power Systems Research, 2001
Abstract The paper discusses the topology and control of a unified power quality conditioner (UPQC) that can be used simultaneously in voltage or current control mode in a power distribution system. In the voltage control mode, the UPQC can force the voltage of a distribution bus to be balanced sinusoids.
