In the new era, with the increasing use of power electronic devices, power efficiency along with system efficiency is playing an important role in the progress of power supply. The fundamental purpose of the electric utility is to provide a sinusoidal voltage at constant magnitude throughout the system. This objective is convoluted because of the non-linear loads present in the system which produce harmonic currents. Hence, our work aims to mitigate harmonics injected by non-linear load system. The mitigation technique utilized in this project is implementation of Harmonic Filters. According to the recommended IEEE 519 power harmonic standards, the total harmonic distortion must be less than 5%. Hence, to reduce the THD, suitable filter design is implemented in this work. The mitigation of harmonics can report significant benefits for industries in terms of installation cost and protection against equipment faults in the power system. The overall process of Harmonic analysis and mitigation is performed using MATLAB/SIMULINK.
