RESUMO

Modern world is more connected each day by all technological means available. This allows more people to communicate, turning the virtual communication road obligatory to the survival of small, medium and large companies, whether public or private. The great technological advance of the 20th century was the large use of the PCs (personal computer), usually called microcomputers. This advance also reached the power electric systems with the digitalization of the substations. These digitalized substations, run the risk of cybernetic invasion, internal or even external. Although the possibility of external cybernetic invasion is small, it exists. In that context, the present thesis proposes the application of a security system for an electric power system. The focus will be the study of intruder detection systems (IDS), on its two basic forms: the IDS by abuse and the IDS by anomaly, using artificial neural networks. These concepts will be tested in a simulated electric power system, with a communication network based on microcomputers, with actual digital relays with the digitalization of the substations.
