摘要：Traditionally when one imagine about power quality, images of classical waveforms comprising 3rd, 5th, 7th etc.harmonics come into picture .On this basis IEEE in team with industries and utilities and academia began to attack thisproblem in “power quality ” from the 80s. However in last few years the term power quality has grown in meaning form asimple power system harmonics. Since the growth of the industries is inevitable with more complex and sensitiveequipments involving semiconductor etc. the power quality engulfed a whole new dimension of errors that appear inpower system. These issues or anomalies are becoming more unavoidable and growing strongly and sensitive equipmentswill become even more sensitive due to the fierce market competition. Now, efficiency and cost are treated as peerparameters of equal importance. In such a situation Active Power Filters have emerged as the solution in which SAPF isemployed for removal of load current harmonics and reactive power compensation .Active filters for power conditioningoffer the following:Reactive-power compensation, Harmonic compensation, harmonic isolation, harmonic damping, and harmonictermination, Negative sequence current/voltage compensation, Voltage regulation. The terminology active filters are oftenseen in different fields apart from power processing.In this work both PI controller based and Hysteresis Band controller, three phases SAPF is used to compensate thereactive power that are elevated in the system due to ihductive load to better the quality and is implemented on threephase wire system. The simulation of the results
