Electric power becomes one of the most essential things in today's world. Maintaining a quality power supply is an important potential problems to the power Engineers. All the primary and secondary distribution systems use three-phase four-wire systems (3P4W) to provide the electric supply to the consumer. Many single phase loads are connected to the three-phase four-wire system which leads to the system unbalance. Since all the loads connected the 3P4W system is not same. Due to improvement in power electronic technology, a lot of power devices are used in the industrial and commercial applications. These types of converters have non-linear characteristics and create a flow of harmonic component in lines. Due to this effect, load voltages, load currents and the neutral current waveform due to unbalance gets distorted. If this component is not mitigated, then it affects the performance of the overall system. In this project, the above effects are mitigated by Fuzzy Hysteresis Controller based series active filter in the phase conductor. By single installation of the filter, load voltage becomes nearly sinusoidal and the distortion in the load and neutral current is reduced significantly. In this project, MATLAB/Simulink model is used to verify the proposed method.
