JPS_V1_N2_RP3 Suhail Aftab Uzma Amin Journal on Power Systems Engineering 2322–0376 1 2 25 36 Energy Conservation, Rehabilitation Techniques, Power Factor Improvement, Transformer The main objective of this research paper is to show benefits of different energy conservation techniques. Different techniques are discussed in this paper and the most beneficial technique that is energy conservation by power factor improvement is analyzed in detail. As a first case study,I performed analysis on University of Gujrat, electrical power system. This case study involves analysis of motors and tube lights installed at the pumping stations and in Engineering Block of UOG respectively, with the help of energy analyzer before and after the installation of required rating capacitors. Power system analysis also done which includes power distribution system losses for example line losses and copper losses of different rating transformers of UOG. Cost and payback period calculation had been done. Cost of capacitors includes both static and automatic capacitors calculations. Second case study is performed on 11 KV Ali Park and Rachna Town feeders to show fruitful results obtained by implementing rehabilitation techniques on the above said feeders. FDRANA Software is used which is capable of calculating voltage drop, power losses and KVARS required for improving the power factor. The results showed by adopting energy conservation techniques not only energy is conserved, it also brings other benefits. May - July 2013 Copyright © 2013 i-manager publications.
