Abstract

The main objective of this paper is to develop Fuzzy controller to analyse the performance of instantaneous real active and reactive power (p-q) control strategy for extracting reference currents of shunt active filters under balanced, un-balanced and balanced non-sinusoidal  conditions. When the supply voltages are balanced and sinusoidal, the all control strategies are converge to the same compensation characteristics; However, the supply voltages are distorted and/or un-balanced sinusoidal, these control strategies result in different degrees of compensation in harmonics. With PI controller the p-q control strategy unable to yield an adequate solution when source voltages are not ideal. Extensive simulations are carried out with Fuzzy controller for p-q control strategy under different main voltages. The 3-ph 4-wire SHAF system is also implemented on a Real Time Digital Simulator (RT DS Hardware) to further verify its effectiveness. The detailed simulation and RT DS Hardware results are included.
