Optimal Placement Of Load Or No Load Regulator Across A Transformer. Reduction Of Copper Losses

Authors : Mathurin Gogom . Tchoffo Moffo . Elvis Tokoh . John Ngundam .


In this article, we present an optimal and reliable approach of the placement of a regulator, with or without load across a transformer. The approach consists in placing the regulator at the secondary of the transformer in order to minimize the copper losses it causes. In fact, the regulator incorporated in the power transformer in order to improve the voltage profile of the electric network increases the copper losses. The usual solution, which consists of placing the regulators on the transformer’s side where the current is lower, helps to reduce the effects of electric arc without resolving the problem of copper losses that it creates. Copper losses are however higher if the regulator is placed at the primary of the transformer. The main objective of this paper is to show that these losses could be minimized. The approach is tested on a five nodes network, and on the Congolese interconnected electricity grid were simulation results obtained justify our claims.
