Abstract
Shunt active filter is used for suppression of current harmonics of nonlinear load to adjust total harmonics distortion (THD) of terminal voltage to the IEEE standards to improve the power quality. A specific control strategy which uses voltage detection of harmonic to reduce harmonics distortion in the waveforms of source current and terminal voltage resulting from distorted source and nonlinear load (together or separately) is applied. Moreover , the proposed control strategy is used to adjust the terminal voltage without effect on the other loads connected to the same common coupling point. This is used to reduce the voltage drop caused by current source by reducing harmonics on distribution power system to improve the power quality. The effectiveness and reliability of the specific control strategy used to control the shunt active filter has been verified by simulation results. In addition, theoretical analysis is presented to confirm the validity of the simulation results
