Abstract
It is expected that, in future, utility service providers will enforce more strict power factor and harmonic standards. Therefore, efforts are being made so that power electronic system or any other load drawing reactive volt-amperes is made to appear as linear load drawing current in-phase with the utility voltage. One of the solutions towards this end is to employ active power filters (APF). This paper presents a control technique for unified power quality conditioner (UPQC), which is a combination of series APF and shunt APF. A control strategy based on unit vector template generation is discussed in this paper with the focus on the mitigation of voltage harmonics present in the utility voltage. Simulation results based on Simpowersystem (SPS) of Matlab/Simulink are presented to verify the effectiveness of the proposed control technique.
