Modified Packed U-Cell Active Filter using Fuzzy Self-Tuning Control Method for Power Systems

In this study, the Fuzzy Self-Tuning (FST) control method that is implemented to Modified Packed U-Cell (MPUC) Active Filter is presented. The MPUC Active Filter application is designed for compensation of reactive power at power systems. The main purpose of MPUC is filtered out undesirable harmonics in the power system. This study deals with the control of active filter topology that is reconfiguration of packed u-cell inverter. The MPUC active filter consists of three cells separated by two capacitors. The FST control method and generation of the reference signal is implemented to MPUC active filter. The MPUC active filter based on the FST control method can eliminate harmonics, compensate reactive power and balance load instability. The generation of current and voltage reference is one of the important points of a proper application of this MPUC active filter. The FST control operation of the MPUC active filter is verified by Matlab/Simulink software. The simulation results show that the applicability of the MPUC active filter with the FST control method and compatible with IEEE 519 and IEC 61000-3-2 Standards.
