Abstract

With the development of the urban power grid, the insufficient transmission capacity on key transmission section and the restrictions on building new transmission channels have become a common problem. As the latest generation of Flexible AC Transmission System (FACTS) devices, UPQC provides an effective method to solve this problem by integrating various flexible control means of FACTS components. In this project a new hybrid power conditioner is proposedfor suppressing harmonic currents and neutral-line currentin three-phase four-wire distribution power systems. The proposedhybrid power conditioner is composed of a neutral-line current attenuatorand a hybrid power filter. The hybrid power filter, configuredby a three-phase power converter and a three-phase tunedpower filter, is utilized to filter the nonzero-sequence harmonic currentsin the three-phase four-wire distribution power system. With the major fundamental voltage ofthe utility dropping across the power capacitors of the three-phasetuned power filter, the power rating of the neutral-line current suppressorcan thus be reduced. The proposed hybrid powerconditioner can effectively develop using Matlab-Simulink.
