چکیده مقاله:
The excessive of power electronics devices in distribution system has evolved the problem of power quality. Arc Furnaces, Variable Frequency Drives (VFD), Computer power supplies play major role in the deterioration in the quality power by injecting harmonics in the utility supply source. This paper represents the effective solution of shunt active power filter for eliminating the harmonics to maintain the quality of utility power supply. In the proposed scheme shunt active filter acts as a current source and eliminates harmonics by injecting equal but opposite harmonics components at the point of common coupling. Simulation of shunt active filter based on instantaneous reactive power theory is carried out using MATLAB-Simulink Toolbox. To prove the flexibility and effectiveness of the proposed scheme two types of loads have been considered and simulation results are observed.
