In this paper load compensation using shunt active power filter (SAPF) is investigated balanced and unbalanced source voltages. PQ and d-q control algorithms are used for compensating the load current. The reference current given to the hysteresis controller is attained from PQ and d-q control methods. The exhibition of the proposed methods is assessed regarding reactive power, source voltage, and source currents, compensating currents and harmonics compensation as per IEEE-519 standard. To find out the suitability of the proposed control method, the paper is assessed under various source voltage conditions under balanced sinusoidal source voltage condition, all control techniques accumulated similar results. Under unbalanced sinusoidal source voltage condition, dq and PQ theories have demonstrated similar result, but in transient response PQ control has better performance. Simulation results are presented to validate the control methods.Refference:
