Abstract: The active power filtering technique is becoming a reliable technology to compensate for the harmonics in the power system network that may be for the three phases or for three phases with neutral network which feed the loads that are non-linear. In this research a detail analysis is done on the various aspect of controlling strategies, working of individual components, explicit application of the components and the technicality involved in these systems. This research describes mainly an application of shunt active power filter to the system for elimination of current harmonics and fixed reactive power compensation. The above explained system consists of a low rated voltage source active power filter and a series connected LC passive filter in each phase. Excluding this no additional switching filter is needed for the current ripple elimination. This reality of this system can be checked by implementing this system in a MATLAB Model. Presently the modern shunt active filter is widely used for medium and high voltage application. In this research the Shunt APF is controlled by instantaneous real and reactive power theory (p-q) theory to compensate the power. By this strategy the Total Harmonic Distortion (THD) in supply current is reduced to a acceptable range. A MATLAB Simulink Model is taken for the investigation and the desired output is obtained for the above said idea.
