Investigation of Electric Power Losses on Primary Distribution Feeder: A Case Study of Sango - Ota Distribution Company, Ogun State, Nigeria

摘要

The role of distribution system in energy management system cannot be over-emphasized; it linked and served the generated energy to final consumers. Sadly, to know, the integrity of distribution system is being questioned due to its inability to return expected profit. This was not unconnected to power loss occurring on the distribution feeders. It was on this background, that this paper presents investigation of electric power losses on primary distribution feeder; a case study of Sango- Ota Distribution Company, Ogun State. The results of the analysis showed that losses experienced on the selected feeders increases annually and the average annual power losses was found to be 4.4555MW, 10.6935MW, 4.3795MW, 4.1635MW and 2.7175MW for Sango, Ota Ind, Idiroko, Odigbo and Ilaro 33kV feeders respectively. The research revealed that most of industries sited in Ota runs at lower power factor due to lack of capacitor and inductive bank and this contributed immensely to power loss on this feeder. It was observed that among the selected feeders, Ota 33kV feeder experienced the highest power losses while the Ilaro 33kV experienced the least power losses.
