Modelagem no domínio da frequência de um regulador eletromagnético de tensão baseado na compensação série

Abstract

The search for solutions to the different problems associated with power quality, in particular the regulation of the supply voltage, has motivated the development of many innovative proposals, which fit satisfactorily within the legislation presently practiced. In particular, although recognizing the wide range of products on the market, the design of devices based on principles and control which are simple in concept and still able to provide competitive costs, lower maintenance requirements, among other things, still present challenges to the research and development of new products. In this context, this paper continues a line of developments conducted by researchers at the Federal University of Uberlândia (UFU), which is focused on the proposition, modeling and development of a new conception of regulating device. The investigations conducted in this dissertation are directed to the mathematical model of the equipment in the frequency domain, as a complement to previous studies which aimed at the time domain representations through the ATP simulator. The use of this modeling strategy presents itself in a simpler and more effective way for obtaining the basic parameters of the regulator equipment and evaluating the effectiveness of the voltage regulation process. To meet such goals, this dissertation highlights the design and physical structure of the machine, presents a prototype already developed of the device, conducts experimental studies of performance and finally establishes comparative terms between the regulator performances through the computational resources originally available and the new formulation proposed here
