Control strategy for voltage sag/swell/harmonic/flicker compensation with conventional and fuzzy controller(UPQC)

This post provides a uniform system of power quality control strategy. This control strategy is in 3-phase and 3-wire system. The device combines a UPQC, shunt active filter with an active series filters in the back to back configuration. UPQC designed for simultaneous compensation of current and voltage harmonics. This paper focus on simple control strategy with voltage sag-swell/harmonic/flicker compensation, fuzzy controller benefits over PI controller. Simulation results based on SIMPOWERSYSTEM by MATLAB / Simulink are presented, and verified the effectiveness of the proposed control technology.
