Despliegue Óptimo de Redes Ópticas para Comunicaciones en Redes Eléctricas Inteligentes

This article shows the optimal design of the optical communications network in smart grids. To analyze the coverage problem, each of the substations is defined with their respective georeferenced coordinates, by means of the algorithm proposed it is possible to create the minimum spanning tree that communicates all the actors in the electricity sector. A series of restrictions are taken into account, such as the performance of each stage in terms of data bit rate, power, bit error rate and jitter requirements. The objective is to limit the distances between the substations in order to avoid additional intermediate equipment such as optical signal amplifiers. The optical fibers analyzed are type G.652, G.652b and G.655 implemented inside the OPGW guard cable deployed on the transmission towers in the electrical system. The parameters to be met by the design of the optical transport network are subject to the ITU-T G.959.1 standard for short distance multichannel applications.
