Análise do consumo de energia elétrica e da eficiência energética em uma indústria de processamento de madeira

In the industries of wood processing (sawmills), where timber is sawn in equipment such as band saws, circular saws, trowel, thicknessers, among others, that mechanically transform this resource and use of electric motors, which are not unusually poorly scaled working or overloaded, often a factor that is not found in these industries and has fundamental importance in the production process is energy efficiency that is achieved by both technological innovation and through all the practices and policies that aim to lower energy consumption, lowering energy costs and increasing the amount of energy offered no change in generation. For both during the design of an electrical installation, both overall and in various sectors of the installation, investigations are necessary, considerations and uses of variables and factors that put into practice the theme of energy efficiency. Therefore, in this paper, these factors were calculated and analyzed for a wood processing industry (sawmill) in the municipality of Taquarivaí - SP, namely: active power, power factor, demand factor and load factor. Where they were small in relation to the literature, these events that occur when devices are connected at the same time and due to the conditions of processing the wood, where the engines have large variations in electricity consumption during the unfolding of the same, due to efforts with the load and idle moments between each machining operation in the equipment

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

A integração da indústria de energia elétrica na América do Sul: análise dos modelos técnicos e de regulamentação.

Os recursos energéticos naturais não estão distribuídos uniformemente pelo globo terrestre, e são raros os países que os têm na quantidade e na qualidade que necessitam para atender as suas necessidades. Ante a essa realidade, o comércio de energéticos tem sido a forma principal de acesso dos países que não os dispõem em relação as suas necessidades. Esse comércio, que muitas vezes é regido por tratados ou acordos firmados entre países ou blocos econômicos regionais, diversificou-se, traspassou fronteiras e, atualmente, tornou-se um item significativo nas pautas de exportações de vários países. A evolução desse comércio tem a favor a alternativa de integração por meio de interconexões estratégicas de redes e da constituição de mercados comuns, que viabilizam a exploração do potencial de complementariedade energética de forma mais racional. Diante desse contexto, esta dissertação apresenta um estudo exploratório que avalia o estado da arte da integração energética sul-americana e faz análises dos modelos técnicos, das regulamentações, das regulações regionais e multilaterais estabelecidas pelos blocos econômicos sul-americanos e pela Organização Mundial do Comércio. De forma complementar, o estudo verifica e apresenta os fatores que podem comprometer o avanço e a instituição de um futuro mercado comum de energia no continente, conclui pela viabilidade do prosseguimento de ações em prol da ampliação da integração da indústria de energia elétrica na América do Sul e tece recomendações. Os resultados e as recomendações deste trabalho oferecem um embasamento procedimental para a gestão e a atuação institucional dos envolvidos no processo de integração energética da indústria de energia elétrica da região sul americana.

Administração limpa e enxuta em sistemas hidráulicos de colhedoras de cana-de-açúcar

Among the important changes in the production processes, it is necessary to guarantee the sustainability of the human enterprises, what makes us to foresee changes in the managerial administration to adapt to a new model, with the insert of the concepts of Clean Production, Cleaner, Lean and Total Productive Maintenance (TPM). The main focus of this work was to elaborate a methodology that made it possible to guarantee the reliability in the waterworks of the sugarcane harvester, identifying and analyzing the manners of flaws, in order to result in the improvement of the environmental and socioeconomic quality in the atmosphere of an industry of sugarcane through the significant decrease of hydraulic oil spill. Through the existent report in ERP (Enterprise Resource Planning), used in a Sugarcane Industry Plant, it was possible to accompany of the operational acting of the sugarcane harvester used during 03 crops, regarding the manners of flaws in the waterworks of the same ones, and, in one of the crops it was elaborated the total control of the waterworks of 5 harvesters. Based on the obtained data and the developed methodology it was possible to develop a software that specifies the electric outlet of decisions.
