Title: Investigation and Analysis of Technical and Commercial Losses in Electrical Military College Substation
Author: Elsamani, Alaa Awad Omer
Abstract: The technical and commercial losses in electrical distribution network in Sudan represent about 20% from the total maximum load. This research presents basic concepts of technical and commercial losses and themain reasons. MILITARY COLLEGE substation was taken as case study in Omdurman area. Calculation of losses was carried out according to the IEC standards requirements for static equipments such as transformers and lines parameters in medium and low voltage level and NEPLAN program was used for modeling and simulaton and the data was collected from Sudanese electricity distribution company-SEDC. Maximum technical losses were found in MILITRY PRION feeder, the losses in 11 KV line are0.604 MW and the voltage drop percentageat the end of the line is14.27%. The minimum losses were found in the WD ELBAKHEET feeder, the losses in 11 KV line are0.011 MW and the percentage of the voltage drop at the end of the line is 1.82%. the research contributed to reduce technical losses in MILITARY COLLEGE substationfrom 1.375 MW and 15.137 MVAr to 0.725 MW and 2.758 MVAr.And this reduction represents47.3% of the total MW losses and 81% of the total MVAr losses in the substaion.Also the annual energy consumed in substation was calculated for each feeder to investigate and obtain the reasons of commercial losses in substation, such as the defected Meters, the pilferage and direct theft of energy. Conculosin and some recommendations was offered for practices and policies to reduc the losses in electrical distribution network.
