Steady State Power Flow Analysis of Unified Power Quality Conditioner (UPQC) [PDF]

2005 International Conference on Industrial Electronics and Control Applications, 2006
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
