Abstract
En Chile la enorme cantidad de hogares conectados a las redes distribuidoras de servicios básicos, junto con el sistema de recolección de información actual el cual consiste en una visita de personal de la empresa a cada vivienda a usuario una vez al mes, hacen imposible la obtención de datos útiles para la industria. Por ejemplo, el consumo eléctrico en hora punta o incluso datos como la cantidad de energía inyectada a la red por cada usuario exigido por la Ley 20.571 de “Net Metering” en vigencia desde el 22 de Octubre del año 2014 la cual permite a los domicilios autogenerar energía y ser retribuidos por sus excedentes entregados a la red.Para solucionar este problema, en más de 40 países a nivel mundial ya se encuentra implementada la tecnología de Smart Metering la cual consiste en la instalación de medidores inteligentes los cuales reportan constantemente el consumo de los clientes a la empresa distribuidora. Lamentablemente esta tecnología aún no ha sido implementada masivamente en Chile debido al gran esfuerzo que significa. En este trabajo se analizan aspectos técnicos de las opciones de Smart Metering como son: conectividad, tipo de arquitectura sobre la que opera, escalabilidad de usuarios y escalabilidad a otros servicios, tratando de buscar el óptimo entre estas características y el valor de la solución.Así idealmente se busca una implementación de Smart Metering económicamente sustentable y adecuada a la realidad chilena.De las tecnologías evaluadas, por motivos de costo de la solución y en busca de no depender de un proveedor particular, se optó por un sistema AMR (Automatic Meter Reading) con una arquitectura de árbol con concentradores que recolectan la información de un grupo de medidores y la envía al servidor. La comunicación se realiza mediante enlace RF en la banda de 910 a 913 MHz y el dispositivo concentrador fue desarrollado particularmente para el sistema en base a computadores de bajo consumo con un dispositivo SDR (Software Defined Radio).La arquitectura completa que soporta el sistema fue evaluada a modo de prototipo vertical considerando junto con el sistema de recolección (Medidor y Concentrador), el almacenamiento y despliegue de datos para usuario final.La funcionalidad de este sistema fue corroborada en todas sus componentes.
In Chile the huge number of households connected to distribution networks of public utilities, along with the current information collection system which consists of a visit by company staff to each user once a month, make it impossible to obtain useful data for the industry as, for example, electricity consumption at peak times or even data such as the amount of energy fed into the grid for each user required by Law 20,571 of "net Metering" in effect since October 22, 2014 which allows self-generating power homes be rewarded for their surplus delivered to the network.To solve this problem, in more than 40 countries worldwide is implemented Smart Metering technology which involves the installation of smart meters which consistently report consumption customers to the distribution company.Unfortunately this technology has not yet been implemented massively in Chile because of the large effort involved. In this paper the main technical options Smart Metering as are analyzed, such as: connectivity, type of architecture on which it operates, scalability of users and scalability to other services, trying to find the optimum between these features and the value of the solution.So ideally, what is sought, is an implementation of Smart Metering sustainable economically appropriate to the Chilean reality.Of the evaluated technologies on the basis of cost of the solution and looking for not depend on a particular supplier; we opted for an AMR (Automatic Meter Reading) with a tree architecture with a hub gathering information from a group of meters and sends it to the server. Communication is done via RF link in the band of 910-913 MHz and the hub device was developed particularly for the system based on low power computing device with an SDR (Software Defined Radio).The complete architecture that supports the system was evaluated as a vertical prototype considered together with the collection system (meter and concentrator), data storage and end-user deployment.The functionality of this system was confirmed in all its components.
