Web Application in Python for Voltage Regulation Calculation in Short Transmission Lines: Development and Validation

Abstract

The analysis of electric power systems requires tools that facilitate understanding of the phenomena associated with transmission lines. Among the most relevant parameters, voltage regulation stands out as a key indicator for evaluating the operational performance of a network. This paper presents the development of a didactic web application implemented in Python, designed to calculate the voltage regulation of short transmission lines through an interactive environment that supports teaching in electromechanical engineering. The tool incorporates a database of ACSR conductors and displays both intermediate and final calculations, promoting active and visual learning. Validation was carried out through complementary academic and reference-based approaches, including educational examples and classical textbook problems. The results show a high level of agreement with traditional analytical methods, confirming the technical accuracy and pedagogical value of the proposed tool. The study concludes that the application represents an open, replicable, and accessible resource for strengthening practical learning in transmission line analysis.
