Technical Loss Reduction on a Distribution Feeder. The Lahan Distribution Feeder in Nepal

Seminar paper from the year 2017 in the subject Engineering - Mechanical Engineering, , language: English, abstract: Distribution system provides a link between the high voltage transmission system and low voltage consumers thus technical loss in a distributed system is high because of low voltage and high current. The main target of the study is to reduce the power losses in a Nepalese existing distribution feeder. Technical losses of existing Lahan feeder and improvement on same distribution system through technical loss reduction is analyzed by implementing the feeder conductor replacement, rerouting and optimum capacitor placement (OCP) methods using (ETAP) load flow simulation. Technical losses for the existing feeder obtain 22% on peak load. Saving on active power by the first initiatives "e;rerouting with replacement of conductors"e; at 11 kV Lahan feeder is found 4%. Saving on active power by the second initiatives "e;OCP"e; which is considered after implementation of a first initiative is found 3.8%. Thus the total feeder loss could reduce to 14.2% from the existing loss of 22% by implementing both initiatives.
