This study presents a diagnostic and strategic planning methodology for the distribution network supplied by the Liminga HV/MV substation in the DRC. Confronted with critical load rates (101.79% for MV/MV transformers, 112% for 6.6 kV feeders) and voltage drops exceeding 20%, the analysis identifies a reinforcement need of 55.56 MVA. The proposed solution includes the installation of eight additional 15 MVA transformers and optimization of the 6.6 kV network topology. Simulations over a 10-year horizon (5% growth rate) validate the improvement in safety margins and power quality.
