The most complete configuration of hybrid filters is the unified power quality conditioner (UPQC), which is also known as the universal active filter. UPQC is a multifunction power conditioner that can be used to compensate various voltage disturbances of the power supply, to correct voltage ...
unified power quality conditioner (UPQC) is a combination of back to back connected shunt and series active power filters (APFs) to a common DC link voltage, which compensates voltage and current based distortions, independently.Using instantaneous active and reactive Power theory ,harmonic detection...
This paper proposes a new connection for a unified power quality conditioner (UPQC) to improve the power quality of two feeders in a distribution system. It is demonstrated how this device is connected between two independent feeders to regulate the bus voltage of one of the feeders while ...
An advanced control approach for power quality compensation using Unified Power Quality Conditioner (UPQC) is presented in this paper. This approach has capability of voltage distortion mitigation as well as current harmonics compensation. In the UPQC control, Series Active Filter (SAF) is controlled ...
This paper proposes a new configuration of UPQC (Unified Power Quality Conditioner) that consists of the DC/DC converter and the super-capacitors for compensating the voltage interruption. The proposed UPQC can compensate the reactive power, harmonic current, voltage sag and swell, voltage unbalance,...

Aiming at the problem of three-phase unbalanced voltage sags in the power system,an energy optimization control strategy for a unified power quality conditioner( UPQC) was proposed. Based on the fundamental wave phasor diagram of UPQC during three-phase unbalanced voltage sags,the optimal steady-sta...
Power quality has turned into an imperative element today because of wide use of power electronics based equipment. Traditional equipment for upgrade of power quality is getting to be lacking. Unified power quality conditioner (UPQC) is one modern device which manages voltage and current defects all...
The Unified Power Quality Conditioner (UPQC) is a custom solution for power quality problems. The equipment corresponds to the back-to-back connection of a series and a shunt active filter, so the topology acquires the characteristics of both filters. It has the ability to compensate for voltage...
