Abstract In this research paper, the shunt active filter (SHAF) is used to improve the power quality of electrical network by mitigating the harmonics with the help of different control strategies (p-q control strategy, Id-Iq control strategy, PHC control strategy) for three phase three wire system. It is quite difficult to optimize the performance of power system networks using conventional methods, because of complex nature of the systems that are highly non-linear and non-stationary. Three phase reference current waveforms generated by the proposed schemes are tracked by three phase voltage source converter in a hysteresis band control scheme. The performance of proposed control strategies has been evaluated in terms of harmonic mitigation and DC link voltage regulation under various source voltage conditions. The proposed SHAF with different control strategies is able to eliminate uncertainty in the system and SHAF gains outstanding compensation abilities. The detailed simulation results using MATLAB/Simulink software are presented to support the feasibility of the proposed control strategy.

This paper presents the fuzzy logic controller for shunt active power filter used to compensate harmonic distortion in a three-phase system. The shunt active filter employs a simple method for estimating the reference compensation current. A fuzzy logic based current control strategy is used to regulate the filter current and hence ensure harmonic free supply current. Classic filters may not have satisfactory performance in fast varying conditions. However, an auto-tuned active power filter gives better results for harmonic minimization and power factor improvement. The proposed fuzzy based shunt active filter maintains the THD well within IEEE-519 standards. The validity of the presented approach in harmonic mitigation is verified by simulation results in MATLAB/ Simulink and hardware prototype.
