Determinação dos parâmetros de compensadores estáticos de reativos e estratégia para o projeto otimizado de reatores saturados

Abstract

Due to the increasing demand of consumption, the electric energy systems have faced, in the current times, problems with its operation, being the voltage control one of the most relevant matters. To provide means to solve such problems, the use of static compensators has emerged, amongst others, as a classical alternative. Although the modern solutions are mainly based on power electronic equipments, in the past, an old fashion compensator using saturated core reactor had been largely used. This is composed, basically, by a magnetic core with special windings operating in parallel with a fixed capacitor. This equipment, due to its robustness, low cost, minor maintenance requirement and good performance, consists in an attractive alternative in relation to electronic proposals when the voltage requirement control is not so strict. However, the technology of this product, appeared in the year of 60, is quite rare documented. This has created a great lack of information regarding the project and construction of these compensators. In this context, the present thesis aims at searching for mechanisms to support the design of the saturated reactor. The searched process, amongst other properties, focuses the optimization of losses associates with the operation of the device. On the basis of these procedures, in addition to computational tools utilizations to predict the equipment performance, a real size saturated reactor is designed, constructed and tested. The results are then used to validate two software (FEMM and SABER) chosen to evaluate the equipment performance analysis before the final construction.
