Steady State Power Flow Analysis of Unified Power Quality Conditioner (UPQC) [PDF]
This paper deals with the steady state analysis of unified power quality conditioner (UPQC). The UPQC, a combination of shunt and series active power filter (APF), is one of the best solutions towards the mitigation of voltage sags and swells problems on distribution network. The analysis is based on active and reactive power flow through the shunt and

Unified power quality conditioner (UPQC) with voltage dips and over-voltages compensation capability
Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. Diverse control techniques have been proposed to evaluate the instantaneous output voltage of the series active power filter of the UPQC but, in most cases, these ...
