Analysis of Technical Power Losses at ILE IFE Distribution Network

Onaopemipo Taiwo

Abstract: As a result of impedances in Transmission lines, power transformers and distribution lines, as well as metering errors, inaccurate meters, improperly read meters, energy theft and administrative errors, some power losses are incurred at the distribution network. Some of these losses are inevitable and it is desired to bring these losses to the barest minimum to improve the overall efficiency of the network. The Ile Ife Electrical distribution network has been selected as a case study. The Ile-Ife distribution network comprises of three (3), 33/11kV injection substations namely: Ilesha, Ondo and AP. These substations are fed from Ajebandele (132/33kV) which is in turn gets its supply from Osogbo. Each substation supplies various 11/0.415kV from which consumers are fed. For this analysis, the method adopted is the modelling of losses in individual components. This entails obtaining the line diagram for the network, conversion of component values (resistance, capacitance and inductance and impedance) to the respective per-unit equivalents as well as the simulation of the equivalent line diagram using 'Power Systems Analysis Toolbox (PSAT)'. The research aims at improving the efficiency of the network such that its performance in the future can be forecasted.
