Abstract

With fast trends in the industry, electricity pleasant turns into very important. Power quality is described as any electricity trouble manifested in the voltage, current or frequency deviations that bring about failure or mal characteristic of the purchaser equipment. Power quality problems may be categorized as quick period voltage variations, lengthy period voltage variations, waveform distortions, transients, voltage imbalance and voltage flicker. Among the numerous electricity pleasant problems, voltage sag, voltage swell and harmonics are extra dominant in the distribution system. To compensate those problems, Dynamic voltage Restorer (DVR) is used. DVR is a sequence compensating device to mitigate voltage sag and voltage swell. It is likewise used as collection active filter to mitigate harmonics. In this work, Modeling of the DVR collectively with optimized ANFIS controller, have been evolved below the MATLAB /Simulink surroundings to mitigate Voltage sag and harmonics in the electricity system. PSO tuning topology is followed for optimizing the ANFIS controller.
