Simulador didático para análise dos transientes de ondas de tensão em uma linha de transmissão similar à transmissão e reflexão de ondas eletromagnéticas

Abstract

The model of education in the last decades has undergone considerable changes from a didactic point of view. With the advancement of technology, the speed of getting information increases and the use of tools that allow the dynamic visualization of contents becomes a strong ally to the teaching-learning process. This work deals with the creation of an interactive tool to visualize the propagation of voltage waves in a transmission line similar to what happens to the transmission and reflection of electromagnetic waves that affect different dielectric means, allowing the insertion of data by the user, to facilitate the consolidation of knowledge. We created the model from the MATLAB GUIDE, which has a graphical interface with action buttons that, when clicked, perform actions such as calculating and displaying the animated graphic. It is important to emphasize that the creation of the program, besides facilitating the understanding, also allows greater familiarization with the computer simulation software and with the parameters used in the transient analysis of transmission lines. Thus, the analysis of transients of voltage waves in transmission lines, which comprises a difficult learning area, for its theoretical nature, becomes easy to assimilate with the use of this didactic-computational tool.
