Abstract

Power quality has turned into an imperative element today because of wide use of power electronics based equipment. Traditional equipment for upgrade of power quality is getting to be lacking. Unified power quality conditioner (iUPQC) is one modern device which manages voltage and current defects all the while. This paper displays the Unified Power Quality Conditioner (iUPQC) with completely fuzzy logic controller for enhancing the dynamic execution of UPQC. The UPQC is a custom power device which is integrated by series and shunt active power filters (APF) sharing a typical dc bus capacitor. Fuzzy control has developed as a standout amongst the most dynamic and productive regions for examination in the utilizations of fuzzy set hypothesis, particularly in the domain of industrial procedure, which don't lend of quantities data information in regards to the data yield relations. In this a simplified intelligent control system for a dual three-phase topology of a unified power quality conditioner i-UPQC is Different from an ordinary UPQC, the i-UPQC has the series filter controlled as a sinusoidal current source and the shunt filter controlled as a sinusoidal voltage source. In this way, the pulse width modulation (PWM) controls of the i-UPQC manage a surely understood frequency spectrum, since it is controlled utilizing voltage and current sinusoidal references, not the same as the conventional UPQC that is controlled utilizing non sinusoidal references. .The proposed concept is implemented to Fuzzy logic controller by using Mat lab/Simulink software.
