A Comparative Analysis on the Effect of Various Controllers for Shunt Active Power Filter

This paper represents the use of different controllers such as Proportionate, Integral, PI and PID and studies its performance on the Shunt Active Power Filter. An active power filter connected in shunt may be used to eliminate voltage and load current harmonics for reactive power compensation. The shunt active power filter has been developed based on control techniques like active and reactive power method (p-q method), active and reactive current method (d-q method) and other algorithms. Considering the simplicity and good performance of the p-q method, it is used in this work for harmonics filtering and the compensation of the shunt active power filter. A theoretical study based on the various control schemes is done in this paper and the theory of p-q control method is implemented in simulation work on MATLAB/Simulink platform and its harmonic compensation results are analyzed.
