This paper deals with the development of an enhanced controller for investigation of dynamic voltage restorer (DVR) compensation capabilities. Two levels, 24-pulse DVR is modeled with a new control scheme to control the switch signal in the voltage sourced converter. A study on voltage sag compensation capability, harmonic elimination, effect of phase shift on DVR sizing, influence of induction motor load and effect of capacitor value on DVR performance have been investigated. Results proved that the DVR is a suitable device for maximum power quality (PQ) compensation. Thus, the developed model and controller will be useful for further power quality studies in a distribution system.
