Simulation and Experiments on One Phase and Three Phase Shunt Active Power Filters

Abstract

Based on synchronous detection method a shunt active power filter for a single phase has been developed. Harmonic pollution is increasing day-to-day by the use of non-linearity devices such as power electronics rectifier, inverters and many other device. Improvement in the quality of power has become the big task for the present electrical society. So we modelled a 1-phase SAPF(shunt power filter active in nature) using the synchronous detection method under which the hysteresis and triangular current controller technique was shown and total harmonics distortion was shown for both the cases. Results based on simulation were highlighted to depict the working of 1-phase SAPF due to non-linearity in the load. To prove the simulation results an experimental setup was also developed using various components in the project work.Also an instantaneous reactive power technique was developed for the compensation of reactive power and reduction in harmonics, and the results of the total harmonic distortion was compared for every case
