Simulador computacional aplicado no ensino de proteção diferencial de transformador de potência

Abstract

The power transformer is one of the most important components in all sectors of the power system, from generation to the use of electric power. Long-term performance does not have to be performed in function of physical performance. To ensure maximum system reliability, power transformers are protected through intrinsic protections, the programs that are part of your design, and external protections, which are related to overcurrent and differential. Transformer differential protection is more expensive, more reliable and more complex from the point of view of calculation, installation and operation methods. For this reason, understanding the factors that influence the method of safety adjustment is essential to ensure the reliability of the electrical system. The purpose of this paper is to show a transformer differential memory simulator developed in JAVA. The simulator that has been used as a tool to support the teaching of activation, presenting itself as a non-learning facilitating agent of the differential protection function.
