Abstract

The fundamental components of harmonic analysis and works linked to it were the main emphasis of this study. The total harmonic distortion is a measurement of the harmonic content in the network as a result of power electronics devices. Electrical Transient Analyzer Program (ETAP) software was used to model and simulate the Okwuzi 33/11/0.415kV distribution network. To ascertain the degree of harmonic distortion in the network, the harmonic load flow analysis tool integrated into the ETAP 19.0 software is used to show the results of the total harmonic distortion (THD) for the network. The results revealed that, at buses 3, 4, 5, 6, 7, and 10, the total harmonic distortion limitations as specified by IEC 61000-3-6:2008 were breached when a harmonic source was connected at bus 6; the point of common coupling (PCC). The first harmonic of bus 6, the point of common coupling, is 8.69 kV, the third harmonic is nonexistent, the fifth harmonic is 0.439 kV, and the seventh harmonic is 0.261 kV. The THD of bus 6 is 6.43%. Bus 8 has the most distorted waveform due to its proximity to the harmonic source relative to all other buses. To remove the network's 5th, 7th, and 11th order harmonics, three single tuned filters were connected. Simulations were performed with and without the single tuned filter to demonstrate the filter's influence in reducing harmonic content, and the results revealed a notable reduction, which improved the power quality and voltage profile.
