HARMONIC ANALYSIS OF A SUB-DISTRIBUTION NETWORK: THE CASE OF A NIGERIAN FEDERAL UNIVERSITY

This paper investigates the harmonic distortion level in subdistribution networks in a university community. Quantitative analysis of load data was used to model the distribution network using occupancy harmonic source modeling. Phone (GSM charging), Compact Florescent Lamp (CFL), Laptop (LAP), Personal Computer (PC), and Television (TV) were discovered to be the highest contributors of harmonics with 16%, 14%, 12%,11%, and 11% respectively. The results showed that four (4) units of the 19 PCCs contributed about 56 % of the total harmonic distortion level. This research underscores the importance of addressing harmonic distortion in academic institutions, contributing to better operational performance
