Desenvolvimento de Plataforma Virtual 3D para realização de ensaios em transformadores.

Abstract

The Electrical Engineering course at UFCG includes the Electrical Equipment discipline, which has a theoretical and a laboratory part. This discipline covers various equipment, such as circuit breakers and transformers, which are essential for the training of engineers. Among the various experiments, the one involving power transformers stands out, as it is the longest and involves the largest number of tests performed. Based on this, the objective of this study is to develop a virtual platform for the Electrical En-gineering student body that allows not only the interaction of the student with a power transformer, but also the simulation of “type” and “routine” tests. For this, the Unity 3D software was used as a basis, as it has characteristics that facilitate the development of 3D structures, objects and maps. The creation of the virtual platform included the modeling of a scenario similar to the physical laboratory in which the experiment was performed, as well as the transformer, character, measuring instruments and other graphic objects necessary to simulate the performance of the tests. The development made it possible to perform tests such as polarity determination, saturation curve survey test, insulation resistance measurement, transformation ratio measurement, short-circuit operation and no-load operation. In addition, the visual inspection procedure was implemented, offering the user the option of viewing the tested transformer, with its respective plate data, and also a model of the transformer without the housing, allowing the identification of the internal parts. Thus, the development of the virtual environment within Unity 3D was able to realistically represent the electrical equipment, the room where the experiments were performed, and the main instruments used to perform the different types of tests addressed. With this, a platform was made available to the academic community that allows access to a laboratory with several tools that allow indepth studies on transformers, without time restrictions, possible to be accessed remotely and that aims to offer accessibility to its users who do not have access to the physical laboratory.
