The paper presents a three-phase unified power quality conditioner using a fuzzy controller. The fuzzy controller replaces the conventional PI controller in this work. The results obtained through the fuzzy controller are found superior to those obtained through conventional PI controller in terms of dynamic response. This is because of the fact that the fuzzy controller is based on a linguistic variable set theory and does not require a mathematical model of the system. Moreover, the tedious method of tuning the PI controller is not required in case of fuzzy controller. Simulations are carried out using MATLAB/Simulink to validate the theoretical findings.

Abstract This manuscript grants a control system for Power Quality (PQ) issues of Unified Power Quality Conditioner (UPQC) based hysteresis controller and augmentation the PQ with the help of numerous optimization methods. In numerous attractive features of UPQC, like voltage sags, voltage swells negative series current and harmonics. Foremost aim of PQ issues is the recompense of the D-FACT devices that origins an undesired effect on bearing. Optimal values for converter of UPQC its presentation can be meaningfully enhanced PQ. This paper discoursed about the UPQC physical process asserts the required meliorate the PQ at DC link integrated. The adaptive control technique for hysteresis developed by the modifying PQ with the use of the UPQC method is also briefly excused. The measurement of voltage sag and swell will be improved and sinusoidal after inoculating current and voltage to the UPQC source current and source voltage. The evaluation results inevitably show the effectiveness of the voltage sag and the voltage swell in the UPQC system based on the Neuro Fuzzy Control (NFC) controller is improved.
