Estudo de viabilidade técnica de um sistema de geração de energia fotovoltaico aplicado a um religador automático de proteção de redes de distribuição de energia em média tensão

Abstract

Modern power distribution systems require increasingly reliable, cost-effective and flexible protection equipment. Seeking to meet these conditions, this course completion paper initially presents the history of renewable energy, discusses the distribution system adopted by energy utilities, focusing on protection device called automatic recloser, its electronic control and distribution that provides supply, as well as presents the photovoltaic system isolated from power generation with its main components. Sequentially, this study performs the project of the application of the photovoltaic system of power generation for the electric power of the electronic control of an automatic recloser of protection used in distribution networks in medium voltage (13,8kV) of Companhia Paranaense de Energia - Copel, to verify the technical viability as an alternative to the usual use of a distribution transformer with low voltage power network (220 / 127V). After the costs of the materials were verified, a brief economic comparison was made between the two presented systems, being demonstrated as the least cost of the photovoltaic system. Finally, according to the information obtained, the result of the work is presented, where it was concluded the existence of the technical feasibility and the economic advantage in the implantation of the photovoltaic system in relation to the conventional system by the energy distribution network suggestions to be explored in new research.
