Abstract

This research investigates the adverse impact of harmonic disturbances present in distribution substations on the electrical installations and distribution network of the University of Cape Coast in economic terms. Power quality analyser using the “very-short time” monitoring duration and referenced against the IEEE 519-2014 harmonics standard was employed to obtain both the voltage total harmonic distortion (THD_V) and current total harmonic distortion (THD_I). The average total harmonic distortions measured on the university was 16.43% with dominant harmonics of the 3^rd, 5^th, 7^th, 11^th and 13^th orders culminating in a reduced true power factor of 0.944. Further computations and analysis on the network showed a reduction of the THD_I level from 16.43% to 8%. Modelling and simulation of the electrical distribution system was also carried out using Electrical Transient and Analysis Program (ETAP) software. The extracted harmonic waveforms and spectrums revealed harmonics of the 3^rd, 5^th, 7^th and 9^th orders to be more dominant within the network. Significant improvement of the true power factor with considerable savings of about Gh¢ 1,161,493.71 per annum was realised. The installation of tuned paralleled passive filters to mitigate harmonics gave a net present value of Gh¢ 2,736,028.00 at a discount rate of 8% with a payback period of 6.23 years.
