Abstract
This work consists in a simulation study of the power flow state of the electricity distribution grid of Abomey-Calavi and the Lome Golfe. For this purpose, the CYME software was used to construct the single line diagrams of each grid based on the actual modeled parameters and data of the generators, busbars, transformers, lines and loads of the network. This power flow resulted in determining the power transits on the sections and the technical losses along the cables and in the transformers. It appears that the distribution grid of Abomey-Calavi and that of Lome Golfe respectively comprise a set of power plants totaling 127MW and 130 MW, a medium voltage system of 93 km spread over three (03) departures and 930 km spread over twenty-eight (28) departures, at the end of 2019. These grids respectively experience technical losses of 12.16% and 9.09% of the total transit power. The purpose of this work is first of all to show the effective existence of enormous losses in the electrical distribution grids in TOGO and BEBIN, then to give some recommendations necessary to reduce these losses. The reduction of these technical losses requires a study of the behavior of the existing grid and a better optimization of the design of subsequent grids.
