Abstract

Problem statement: Now days, power quality has been given attention due to the intensive use of power electronic equipments in all types of industries such as steel, paper, textile industries and so on. These power electronic devices induce harmonic distortion into the supply lines which gives rise to many undesirable effects. Approach: This study presents a new method for harmonic and reactive power compensation with a Fuzzy logic controller and a new control algorithm for active power filter to eliminate harmonics and compensate the reactive power of three phase diode bridge rectifier with RL load. The Fuzzy logic controller was used to predict the reference current values and the firing pulses were generated using hysteresis current controller. The system was modeled and simulated using MATLAB/SIMULINK power system toolbox. Results: The total harmonic distortion for the system is reduced from 29.16-1.08% using the proposed fuzzy logic controller based shunt active filter. Conclusion: The simulation results found were quite satisfactory to eliminate harmonics and improve the power factor for non linear loads.
