Kalman Filter Based Unified Power Quality Conditioner for Output Regulation

The Electrical power system contains a wide range of electrical and power electronics components in industrial and commercial applications. The power quality will be affected by various factors like ripples contamination, voltage sag and voltage swells due to the increase in loads of non-linear type like large power electronics converters such as IGBT and GTO, rectifiers, voltage and current glittering and switching of loads respectively which also affects the perceptive loads to be fed from the system. In this paper the compensation of harmonics and reduction of voltage sag/swells by using Kalman filter based UPQC is introduced. The aim of this paper is to regulate voltage of the source side of distribution line against any power quality issues like balanced and unbalanced voltage sag and reducing harmonics by using Realization of Multilevel Inverter using Intelligent based UPQC. The promising results are presented using MATLAB/Simulink.
