Controle preditivo de estados finitos baseado na teoria p-q para regulação de tensão e compensação de harmônicos em um GIAE isolado

Abstract

This work deals with a predictive finite set control together with the Instantaneous Power Theory (p-q theory) for parallel compensation of an distributed off-grid generation system based on a self-excited induction generator (SEIG), ensuring power quality through voltage regulation and harmonic compensation. Furthermore, the controller reference signals are calculated from active and reactive power obtained by the p-q theory, in order to perform an optimized control. The inverter employed is a three-leg voltage source inverter (VSI), which is a well known simple solution for this application. Since the inverter has a finite switching possibilities, a discontinuous control is chosen to predict the next switching state that minimizes the cost function, for that, a FS-MPC strategy is defined. Simulation results are presented in this work in order to validate the proposed control system.
