• Abstract:

  At the National Technological Institute of Mexico, Veracruz Campus, in the Electrical Engineering program, the course " Modeling of Electrical Power Systems " is taught in the 7th semester. This course provides electrical engineers with the ability to interpret, represent, calculate, and explain the behavior of loads and power flows in an electrical power system, including analysis under fault conditions, in order to operate them efficiently. 
  It introduces students to the methodological analysis of interconnected electrical power systems to understand load management in normal or transient operation through transmission lines, substations, and electrical power distribution networks. See Figure 1
  This research project seeks to address the academic challenges faced by electrical engineering students in learning how to calculate short-circuit currents under symmetrical unbalanced fault conditions in subtransient time.  
  Based on a historical and methodological analysis of calculation tools in electrical power systems, there is a clear need for a teaching resource that facilitates the understanding of these complex concepts and, at the same time, allows students to visualize each step of the calculation procedure.  
  In this regard, the project proposes the creation of an accessible and practical tool in Excel format that contributes to improving accuracy and understanding in the analysis of unbalanced faults.
