Abstract: This paper investigates the impact of inte-grating a 35 MW industrial load into an electrical transmission network, with a focus on the role of the Static Var Compensator (SVC) in voltage regulation and system performance enhancement. The added load induces a voltage drop below 0.9 p.u., threatening dynamic stability and potentially triggering unwanted phenomena such as electromechanical oscillations or protective device misoperations. These disturbances are further exacerbated by a decrease in the power factor due to increased phase shift between voltage and current, leading to higher system losses. The SVC demonstrates high effectiveness in mitigating these effects by dynamically injecting reactive power and restoring voltage levels close to nominal values. Its thyristor-controlled operation provides fast and adaptive compensation, outperforming traditional fixed capacitors and reactors in transient response. Using real-world data from the Congolese power grid, this study employs simulation-based scenarios to evaluate the SVC’s performance under local operating conditions. Results confirm that optimised reactive power com-pensation enhances grid reliability and facilitates the integration of heavy industrial loads. Recommendations are proposed for efficient SVC deployment in developing electrical infrastructures.Abstract: This paper investigates the impact of inte-grating a 35 MW industrial load into an electrical transmission network, with a focus on the role of the Static Var Compensator (SVC) in voltage regulation and system performance enhancement.
