Proposta de metodologia para gestão de produção, visando redução no consumo de energia elétrica em uma unidade fabril do setor de bens de consumo

Actually the energy efficiency is making more space in the industry, due to the search for the sustainability, the electrical energy costs reduction, the goals achievement or the efficiency of production processes. In consumer goods industries, such a beverage industry, as the work is based, the productivity is directly related to the electrical energy consumption. The development of methodologies and/or routines, in addition to some tools which allow to align more efficiently these two aspects (production and consumption of electrical energy), in the viewpoint of the Energy Conservation, is very important. In this case, the study will show the Plant Modulation concepts, a production management methodology, based in some factors related to the productive process, installed equipment, production supplies and energy cost. The proposed methodology was implanted in a plant along 2015 and show the results, in face to confirm its efficiency. Finally, in this study, it was shown the capacity of Plant Modulation to positively impact in the energy efficiency inside a big industry

Geração distribuída de energia elétrica e panorama fotovoltaico brasileiro e português

This work presents a study on the design of a photovoltaic system connected to the grid.It discussed the main characteristics of the solar cell which is the basic component for the manufacture of solar modulethe main components of the photovoltaic system and the steps of the photovoltaic and electrical design of the system, ranging from the choice of the photovoltaic module to the dimensioning of the components of the electrical installation.In addition to the technical design, this work contains a complete comparative analysis of the current situation of photovoltaic generation distributed in Brazil and Portugal, through incentive programs to energy use as well as current legislation in both countries

Estudo comparativo da proteção da rede secundária de uma distribuidora de energia elétrica utilizando chave fusível e seccionalizador monofásico

The objective of this work is to conduct a comparative study between the fuse key and the single-phase seccionalizador, which are protective equipment used in an electricity distribution networks. This study has also the purpose to reduce the number of electrical power breakdown. Distribution networks are not free from faults, disturbances and failures, then the occurrence of adversities on the network, which may be transient or permanent faults, results in the interruption of electric power. Thus, there are protective systems of distribution networks, which aims to ensure that the electric system continues to function. The incidence of transient faults in the distribution network of this electricity company was used to generate immediate shutdown of customers due to the bad use of fuses as protective equipment by the reclosers. With the use of the fuse switch in the distribution network, there was the immediate shutdown of customers, however, using the single-phase seccionalizador as protective equipment by the reclosers, there are three attempts to restart the electricity power. As the attempts to restart the electricity power are able to eliminate a transient fault, not causing shutdown of any costumer, with the implementation of single-phase sectionalizers to replace the fuses, the number of company shutdowns due to transient faults was reduced by 47.6%
