This paper shows the method of improving the power quality using shunt active power filter. In order to protect the supply system from current harmonics, we have to use the active power filters. These are used to compensate the reactive power compensation, but the performance of active power filters are based on various control strategies. This paper presents the complete examination to estimate the working of SHAF for generating the current references under steady and transient for balanced, unbalanced and non-sinusoidal conditions by using PI controller. The P-Q theory and synchronous reference frame theory, which are widely used in SHAF. The most validate results obtained by simulation with matlab/simulink software are carried out with PI controller for P-Q control theory for various voltage conditions like balanced, unbalanced and non-sinusoidal conditions and dynamic load changes.

In Series

Series active filters, besides the dc voltage regulators, incorporate controller such as voltage controller and hysteresis band controllers, etc.. The conventional PI controller suffers from the significant drawback of having a high content of ripples and the low speed due to variable switching frequency caused by the usage of hysteresis controllers. In order to overcome this shortcoming, two different control strategies (i.e., sinusoidal fryze voltage control and adaptive tabu search-sinusoidal fryze voltage control strategy) have been developed in this research work. The performance of SAFs has been analyzed by using these current control strategies. The proposed ATS-SFV control strategy based voltage controller yielded better performance as compared to those obtainable from the SFV control strategy. The comparisons of the proposed strategies among themselves facilitate a need-based selection of them for the supply system. To realize these control strategies, MATLAB/Simulink-based models have been developed for simulation.

Abstract Current harmonics are one of the most common power quality problems and are usually resolved by the use of shunt active filters (SHAF). Control strategies (p-q and id-iq) for extracting the three-phase reference currents for shunt active power filters are compared, evaluating their performance under different source conditions. Three-phase reference current waveforms generated by proposed scheme are tracked by the three-phase voltage source converter in a hysteresis band control scheme.The performance of the control strategies has been evaluated in terms of harmonic mitigation and DC link voltage regulation. The proposed SHAF with different fuzzy M.F.s (Trapezoidal, Triangular and Gaussian) is able to eliminate the 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 proposed control strategies.
