RESUMO

In its core, this thesis is concerned with a new technique in naturally saturated reactors basic projects, as they are applied in power system networks. Such a technique faces each and every kind of reactors and, more than this, it offers the necessary tools to deal any innovation in this particular field of engineering. Therefore, generality is the main characteristic throughout this report. As part of this technique, mathematical models have been developed to represent the naturally saturated reactors. As long as these reactors have the same general characteristic, the models are effective to represent any type of naturally saturated reactors. The mathematical models were developed to be used along with EMTP-ATP program since it is largely used for power system planning all over the world. Although, this very same kind of representation has been proposed by others researches, no one of them has succeeded in making it correct for high-current operations which appears during transients. These currents and conditions are seen here in this work. Finally to consolidated and refine the presented technique, reactors prototypes have been designed and manufactured according to what it is established by this technique. The prototypes have been tested and the testing results show the adequacy of this technique to design naturally saturated reactors and, consequently, the consistency and accuracy of the developed mathematical models. Among many other contributions of this research, and as a result of the technology developed, there is a study about the costs of a naturally saturated reactor. Its conclusions will be very useful for manufacturing companies and other researchers as they will find themselves deciding about the applications of naturally saturated reactors
