Following a theoretical study of static compensation devices, we have developed robust calculation methods for filter- compensators (D.C.F). Our work, based on comparative and statistical analysis, allows for the adjustment of technical parameters to reduce voltage distortion, improve wave quality, and minimize installation costs. These solutions provide efficient and economically viable tools for the metallurgy and energy sectors.frThesis
