This paper deals with a three-phase unified power quality conditioner (UPQC), with a combination of shunt active power filter and series active power filter is used to eliminate supply current harmonics, compensate reactive power, voltage sag and voltage swell compensation on distribution network. The performance of the active power filter mainly depends on control strategy used to generate ref...

This paper, presents a new unified powerquality conditioning system (MC-UPQC) , The response of the Multi converter unified power quality conditioner, for different types of controllers are studied. This paper capable of simultaneous compensation for voltage and current in multibus/multifeeder systems. In this configuration, one shunt voltage-source converter (shunt VSC) and two or more series ...

ABSTRACT This paper presents a system that provides photovoltaic generation as well as the functions of a unified power quality conditioner (UPQC). The system can be controlled for current harmonics and reactive power compensation simultaneously by using a converter operating as active shunt filter. The other converter is used as active series filter and it compensates voltage harmonics or volt...
