This article presents the properties of electric power networks for use as a channel for transmitting telecommunications signals. It starts by exploring the principles and theoretical basis for calculating power lines' critical technical parameters, referring in detail to the following primary parameters: inductance, capacitance, conductance and resistance. It then deals with e secondary parameters (most useful from a telecommunications perspective): characteristic impedance and propagation constant (the attenuation constant being the latter's real component). Different topologies and low- and medium-tension aerial power line structures are verified; a mathematical model is then proposed to analyse their behaviour at high frequencies, extending to most aerial electric power distribution systems in Colombia. This work includes some of the results from previous research which was known as "Using power line telecommunications (PLT) technology for designing a solution for accessing the broadband internet in rural areas of Colombia" by the present author and the Pilot University of Colombia. The proposed mathematical model provides a tool for making theoretical calculations applicable to PLT.
Este artículo presenta las propiedades de las redes de energía eléctrica para su utilización como canales para la transmisión de señales de telecomunicaciones. Comienza explorando los principios y fundamentos teóricos para el cálculo de los parámetros técnicos críticos de las líneas eléctricas, por lo que trata con detalle lo referente a los parámetros primarios: inductancia, capacitancia, conductancia y resistencia, y, asociados a estos, los parámetros secundarios (más útiles desde el punto de vista de las telecomunicaciones): impedancia característica y constante de propagación; de esta última, su componente real, la constante de atenuación. Se verifican las diversas topologías y la estructura de los sistemas eléctricos de potencia para líneas de media y baja tensión aéreas y se propone un modelo matemático para analizar su comportamiento a altas frecuencias extensible a la mayoría de los sistemas de distribución aéreos de energía eléctrica colombianos. El trabajo incluye una parte de los resultados de la investigación denominada "Diseño de una solución a través de la tecnología PLT (Power Line Telecommunications) para acceso a Internet de banda ancha en regiones rurales de Colombia", realizada por el autor con la Universidad Piloto de Colombia. Mediante la utilización del modelo matemático propuesto se tiene una herramienta teórica de una parte de los cálculos aplicables a PLT.
