The goal is to publish the highest quality research regarding applied mathematics and energy systems that cover all the engineering areas for solving complex and current issues. The Journal selects the articles based on high-quality standards, and it is edited by the Universidad Tecnológica de Bolívar.</p> <p><strong>ISSN:</strong> 2745-0120 (<em>Online</em>)<br><a href="http://creativecommons.org/licenses/by/4.0/" rel="license"><img src="https://i.creativecommons.org/l/by/4.0/88x31.png" alt="Licencia Creative Commons"></a></p> https://revistas.utb.edu.co/index.php/tesea/article/view/439 Construction and Simulation of a Planar Transformer Prototype 2021-12-15T03:47:24+00:00 Sebastian Guarin sebas1302@utp.edu.co Sergio Velarde svelarde@utp.edu.co Edwin Castaño galeanoe@utp.edu.co Alexander Molina-Cabrera almo@utp.edu.co <p>This paper illustrates the design and building of a planar transformer prototype with a 1:1 transformation ratio for high-frequency applications in power electronics. By using reference literature and considering the ferrite core dimensions, the windings were conceived and exported to Gerber format using PCB design software. The transformer prototype was then assembled and tested under laboratory conditions for frequencies from 800 Hz to 5 MHz, which showed a sinusoidal wave at the transformer output from 1.3 kHz onwards and a better performance starting at 10 kHz, where the loses were significantly reduced and the transformation ratio was closer to the originally designed. As a final step, a finite element method (FEM) analysis was carried out to understand the electromagnetic flux behavior using a 3D Multiphysics simulation software. The 3d building process and details are explained step by step and the resulting magnetic flux density is graphically shown for the core and the windings.</p> 2021-12-15T00:00:00+00:00 Copyright (c) https://revistas.utb.edu.co/index.php/tesea/article/view/440 Implementation of an Energy Management System in Colombian Manufacturing - A Methodological Approach 2021-12-15T03:55:57+00:00 Juan David Marin Garcia {juadmaringar@unal.edu.co Juan David Marin Jiménez jdmarinj@unal.edu.co Sandra Ximena Carvajal Quintero sxcarvajalq@unal.edu.co <p>This paper aims to analyze mechanisms such as the Energy management systems approach in industry 4.0. The paper is a review of techniques for optimizing energy consumption with energy efficiency, advanced metering infrastructure and<br>rational and efficient use of energy to reduce the pollution as well as to strengthen Industry 4.0 models and the monitoring and management opportunities that exist with the implementation of this models in Colombia.</p> 2021-12-15T00:00:00+00:00 Copyright (c) https://revistas.utb.edu.co/index.php/tesea/article/view/441 Impacts of the Inclusion of Distributed Generation on Congestion of Distribution Networks and in the Islanding Operation Capability 2021-12-20T14:11:52+00:00 Jose David Beltrán Gallego jbeltrang@unal.edu.co Leidy Daniela Castro Montilla ledcastromo@unal.edu.co Alexandra Castro Valencia alcastrova@unal.edu.co Camilo Augusto Giraldo Muñoz cagiraldomu@unal.edu.co Dahiana López García dahlopezgar@unal.edu.co <p>The growing demand for electricity in the world has led to power systems having to constantly increase their generation capacity and expand their transmission and distribution systems. Consequently, distributed generation has positioned as a technology able to integrate generation close to consumption centers, freeing up capacity in the transport systems, which can be translated into a deferral of investments in network expansion. Therefore, this paper analyzes the impact of the inclusion of distributed generation in the congestion of a typical distribution network and evaluates the potential of providing the island operation capability ancillary service in a section of the system to identify the possible challenges and benefits that the development of this technical support service could have in typical Colombian distribution networks.</p> 2021-12-15T00:00:00+00:00 Copyright (c)
