Evaluating the implementation of automatic recomposition systems on electricity distribution networks in Brazil

Electricity distribution systems based on aerial networks are susceptible to transient or permanent failures that can interrupt power supply in affected sections of the grid. In recent years, there has been great concern in Brazil over the need to modernize the supervision and control systems of electric utilities, leading to huge engineering efforts and significant investments in automation. The automation of power distribution networks contributes to improving quality indicators by isolating faulty sections of the grid through remote controls for opening and closing devices, as well as by transferring non-faulty sections to alternative supply sources. This paper presents the results of a statistical study carried out in a sample of a system already implemented in a power distributor that compares quality gains achieved through the Structural Logframe (Matriz Logica Estrutural - MLE) methodology and applies a multi-criteria decision model to use in Live Working area.
