Abstract:

The growing interest in power quality has led to variety of devices are designed for mitigating power disturbances such as harmonics caused due to different problems. By minimizing Total Harmonic Distortion (THD) the Harmonic Pollution will be reduced and Power Quality will be increased. Different types of load draw non - sinusoidal current from mains. This non - linear load appears to be the main source of harmonic distortion. Thus the main aim of shunt active filter that comprises of PI Controller, filter hysteresis current control loop and DC link capacitor is used to mitigate Total Harmonic Distortion (THD). Thus, in order to overcome these harmonic problems it is verified using MATLAB/SIMULINK package. Active filters are used to eliminate current harmonics near non – linear loads. Here the two methods are compared Instantaneous reactive power theory and sinusoidal theory. The results of both the methods are shown on the basis of the MATLAB/SIMULINK. Thus, following thesis gives the overview of the harmonic problems and its impact on power system and how shunt active filters mitigate these harmonics using MATLAB.
