Abstract

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