AbstractImprovement in power loss, voltage drop of electric power distribution systems have become a topic of increasing concern in Laos, because of rapid load growth, the wide geographical area it cover and high loss level in the power systems. Since loss is one of the basic parameters indicating the efficiency of the system, loss reduction is also necessary for efficiency improvement of the power system. The aim of this study is to analyze the power loss of the Vangvieng District distribution system and find the best way of reducing high systemic losses. Using technique of capacitor placements and increasing the capacity of distribution transformers in the primary distribution system, losses have been reduced effectively. The result of this study prove that not only loss reduction but also alternative improvements involving the power factor and the voltage profile were achieved with these loss reduction techniques. Analysis has been considered in three cases. Losses of Vangvieng District Distribution system were evaluated in existed case to measure the actual technical losses of the system, capacitoring case has been analyzed for loss reduction of the system and economic analysis case for evaluation the cost of losses and present worth savings. The economic evaluation of Vangvieng District distribution system has been studied for economically feasibility of loss reduction techniques, economical analysis was only made with one cost of energy.
