Modelagem trifásica de um Regulador Eletromagnético de Tensão com controle independente por fase

Abstract

The search for solutions to several problems related to power-quality, such as voltage variation and imbalance, has resulted in proposals for innovative devices that comply with the applied standards. Therefore, despite the recognition of a wide range of products on the market for this purpose, the design of equipment based on simple control and principles, competitive cost and less need for maintenance, still presents a challenge for research and development of new products. In this circumstance, the present work continues the explorations carried out by researchers from the Group of Power-Quality Research (NQEE) at the Federal University of Uberlândia (UFU), whose focus is to propose a new concept for modeling and development of voltage regulating devices. The aforementioned researches have evolved and the research developed in this Completion of Course Work aims at the three-phase modeling of this device with independent voltage regulation control per phase. This modeling complements the previous investigation, making it possible to analyze its performance not only related to the voltage variation indicator, but also to the voltage imbalance indicator, consequently. Unlike most of the previous developments, modeled on the ATP software, the modeling contemplated by the present work was done by the Matlab software, using the Simulink tool.
