Abstract

The present work of curricular integration has as objective the development of a computational tool for the solution of power flows in radial and unbalanced distribution networks, this tool can be used as a playful element to improve the teaching processes in the preparation of future engineers. The computational tool contains power flow solution methods which use three-phase alternating electrical circuit equations to obtain more accurate results or linearized equations which simplify mathematical calculations and thus reduce simulation times. The proposed methods are Forward and Backward and Linear Method, whose software implementation makes use of the information of the IEEE 13-bar system, which is an unbalanced system with overhead and subway lines, in addition to other particular characteristics. For the validation of the results obtained through these methods, we proceeded to compare these values with results obtained with commercial software using similar solution methodologies to those applied, which in this case were PowerFactory DIgSILENT and CYME. In order to validate the programmed methods, calculations and simulations are performed for a test network of 33 unbalanced busbars, obtaining similar results in both cases, duly validated by results obtained in the aforementioned commercial software. A graphic interface is implemented for the use of the generated programs, which allows visualizing the results of voltages and angles of each bus, as well as the power in each branch and its losses
