Harmonic Distortion Evaluation And Reduction In Radial Distribution System

Prof S.Parthasarathy, E.Jeyasri

In electric power systems due to the integration of power electronic devices, the power quality issues has been raised and has led to waveform distortion. As a consequence of Harmonics the strange condition at various electrical equipment that are connected to the power systems has been created. As a result of this, current Total Harmonic Distortion (THDI) values violates its limit as mentioned in standard specified by IEEE 519- 1992.This paper deals with the conventional design of passive harmonic filter for Radial Distribution Systems (RDS).The test system is simulated in DIgSILENT 14.1.6 Powerfactory.The performance of the proposed filter is analyzed on IEEE 9 bus and IEEE 34 bus RDS. The investigations validate the effectiveness of the proposed passive harmonic filter.
