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.
