  ABSTRACT: Voltage stability is a major challenge for African industrial power networks, where highly inductive loads and variable consumption profiles compromise supply quality. This article presents the design and evaluation of a Static Var Compensator (SVC) controlled by a Mamdani fuzzy regulator, applied to the industrial network of Maloukou (220/110 kV) in Congo-Brazzaville. After recalling the analytical stability criteria and establishing the mathematical model of the SVC, the fuzzy regulator is developed and then integrated into a Simulink environment. Comparative simulations highlight a clear improvement over PI control: stabilization time reduced to less than 0.45 s, voltage maintained within the 0.98 - 1.02 p.u. range, damping of transient oscillations, and about 15% reduction in active losses. Beyond these performances, fuzzy logic proves robust against realistic disturbances (measurement noise, processing delays, sudden load variations), confirming its relevance as a tool for modernizing African power networks. This work paves the way for extensions towards hybrid regulators and the integration of intelligent solutions to support the energy transition in Central Africa.
