Emulación de un sistema de distribución de 13.8 kV para la elaboración de prácticas en el Laboratorio de Distribución de Energía Eléctrica

Abstract

In the present degree project, a 13.8 kV scaled distribution system will be designed and implemented, considering the most used wire lengths and gauges of electric conductors used by electric companies, both in primary feeders and secondary circuits, this will allow the integration of theory and practice by doing experimental studies in the Electric Energy Distribution Laboratory at National Polytechnic School. The distribution system’s feeders will be represented only by their series impedance calculated with the application of the software CYMDIST of CYME using a per-unit (p.u.) based scaling method, considering just resistance and inductive reactance since the feeder lengths are small enough to consider them as short lines. The conductor resistance will be built using power resistors, while iron core coils will be used for the inductive reactance and the system load will be respectively dimensioned and the load will be emulated with a 2 W LED spotlight. Voltage and current measurements in several points will serve to identify voltage drops, as a function of the wire gauges and distances, these parameters are compared with those obtained virtually by applying the aforementioned software and MATLAB. The results will be visualized digitally.
