Abstract: The quality of the electric power in distribution systems gets retrograded because of the introduction of low order harmonic currents due to non-linearity of adjustable speed drive systems. This substantiality of non-linear loads turns our attention towards power quality in the power distribution systems. In power systems, harmonics are taken as the main problem attributable to the use of power electronic devices in various applications. Active power filters are commonly used to mitigate these harmonics. Three phase shunt active power filters are used to eliminate the harmonics arising due to adjustable speed drive systems fed from voltage source inverter. Synchronous reference frame algorithm is used to extract the compensating currents. The control signal to the three phase shunt active power filter is achieved with the help of hysteresis current control method. The three phase shunt active power filter for current harmonic mitigation with a variable speed drive system as a non-linear load is simulated through MATLAB/Simulink Software and the THD is arrived as per the IEEE 519 recommendations.
