Nonlinear electronic devices and increasing applications of power electronic equipment induce large-scale harmonic current/voltage distortions in power systems, which influence the efficiency and reliable operation of the entire system. A shunt active power filter (SAPF) can be taken into consideration as a useful technical solution to mitigate harmonics as well as reactive power compensation in the modern power distribution system. Therefore, the design and implementation of reliable power filters that diminish current and voltage harmonics to fulfill IEEE-519 harmonic distortion limits and the power quality requirements is a substantial requirement of modern power systems. In this paper, the design and implementation of the bandpass filter (BPF) based proportional-integral (PI) controlled SAPF is presented to regulate total harmonic distortion (THD) well within IEEE-519 and IEC 61000 standards. The presented BPF based PI control method provides better harmonic rejection capability compared with the low pass filter required by the instantaneous p-q theories. Constant DC-link voltage control is also achieved during susceptible load changes. The presented method can be implemented in both single and three phase power systems. The various results are conducted to confirm the advantages and effectiveness of the presented BPF based current controller for the SAPF in comparison with the other representative control methods.
