Abstract

The power quality improvement of a sensitive load by an unified power quality conditioner (UPQC) is presented. The UPQC, consists of back-to-back connected series and shunt active filters, is modelled using a state-space-averaging technique to analyse its behaviour. The enhancement of shunt active filter performance is achieved by applying a moving time window method. The performance of UPQC under load nonlinearities and source disturbance conditions is investigated using simulation as well as experimental results
