Es un proceso complejo que impacta sobre la ejecución de los proyectos. El presente trabajo propone una función programada en MATLAB, para la selección automática del modelo ideal de baterías de plomo-ácido para la alimentación de respaldo de los centros de comunicaciones, a partir de tablas de datos de catálogo. A partir de estos datos, se identificó la distribución logarítmica como la que caracteriza las curvas de tiempo de autonomía en función de la corriente de descarga. Se ajustaron los modelos de regresión correspondientes y se utilizaron las ecuaciones resultantes para seleccionar la cantidad y capacidad de baterías apropiadas para respaldar cargas específicas, en períodos de tiempo no especificados por el fabricante. De esta manera se logra una herramienta que contribuya a la formación de los proyectistas y operadores de redes de comunicaciones.]]></p></abstract>

It is a complex process that impacts on the execution of projects. The present work proposes a function programmed in MATLAB, for the automatic selection of the ideal model of lead-acid battery for backup power supply of communication centers, from catalog data tables. From these data, the logarithmic distribution was identified as the one that characterizes the autonomy time curves as a function of the discharge current. The corresponding regression models were fitted and the resulting equations were used to select the appropriate number and capacity of batteries to support specific loads, in periods of time not specified by the manufacturer. In this way, a tool is achieved that contributes to the training of designers and operators of communication networks.]]></p></abstract>
