Simulación de un canal PLC para AMI para empresas distribuidoras de energía eléctrica con fines didácticos y de investigación

Jorge E. Veglia, David Luis La Red Martínez, Reinaldo J. Scappini

Resumen


Gran parte de las Infraestructuras Avanzadas de Medición (AMI, Advanced Measurement Infrastructures), desplegadas en los sistemas de distribución de energía eléctrica para el registro de los parámetros facturables y de calidad de servicio utilizan las mismas redes de energía como medio de comunicación (PLC, Power Line Communications). Para ello, utilizan la banda de frecuencias NB-PLC (Narrowband PLC, o PLC de banda estrecha, entre 90 y 500 KHz), con esquemas de modulación tales como la Multiplexación por División de Frecuencias Ortogonales (OFDM, Orthogonal Frequency Division Multiplexing). Dado que las redes de distribución de energía no se diseñan como canales de comunicación, presentan serios desafíos para la obtención de comunicaciones confiables. En este trabajo se propone modelar en Matlab/Simulink® el canal PLC con fines de docencia e investigación, para una configuración típica de distribución en Baja Tensión.
