The effect of passive filter on the 3rd, 5th and 7th harmonic in nonlinear load

Abstract

This project discusses the effect of passive filter on 3rd, 5th and 7th harmonic in nonlinear load. The passive filter considered is the single tuned harmonic filter. In the design of the filter, the passive elements of the filter are derived. Studies are made to investigate the effectiveness of using single tuned filter in reducing harmonic distortions and also to determine the optimal location of installing the filters. The effects of power factor correction capacitor and load parameters variation on harmonic distortion are also investigated. Simulation results show that the single tuned filter is effective in reducing harmonics. The study also proves that passive filter give better performance in reducing harmonics when it is placed close to the harmonic producing loads.
