This thesis deals with the optimization of power consumption in an intelligent digital home, where the appliances are powered either from a distribution network and also from the photovoltaic source owner. The optimization of consumption we will see both economically and in terms of load distribution network. Renewable power supply operates in a green bonus. Optimization is done using the backup system and the unit Home Manager by SMA. Backup system in collaboration with the batteries will store power from photovoltaic sources, if you're not consumed by appliances in the home. Since it may be a smart home, which is performed by means of inteligent wiring components and accessories (Inels system from the company ELKO EP), is possible thanks to intelligent multimedia extensions and appliances also optimizme consumption.

[pt] A presente dissertação tem por objetivo geral validar em condições reais de operação, a técnica (desenvolvida em ambiente laboratorial) de monitoramento remoto de baterias estacionárias e como objetivos específicos identificar as limitações das tecnologias convencionais de monitoramento de baterias estacionárias, avaliar a confiabilidade do método de monitoramento remoto proposto e justificar a alternativa tecnológica proposta à luz do impacto econômico que dela decorrem. O desenvolvimento deste tema de dissertação de mestrado foi motivado pelas contribuições que poderá produzir para a Light e demais empresas dos setores elétricos, óleo e gás, bancário, de telecomunicações, entre outros setores que utilizam baterias estacionárias. A Light e o CPqD realizaram o projeto de PeD Light-Aneel 033/2008. Este projeto teve como objetivo o aumento da confiabilidade dos serviços auxiliares das subestações e redução dos custos de manutenção. Para tal efeito, foi desenvolvido um sistema automatizado de monitoramento e gestão individual e remota de todos os elementos que compõe o banco de baterias. A pesquisa de mestrado avaliou, quantitativamente, a confiabilidade da medição remota realizada na subestação Baependi da Light, na cidade do Rio de Janeiro. A metodologia aplicada na presente dissertação consiste em estudos estatísticos (Testes de hipóteses paramétricos e não paramétricos) para comparação de resultados de tensão elétrica e impedância obtidos em condições reais de operação (Medições SIMBA-GEBAT) em relação ao equipamento portátil de medição. A pesquisa validou aos níveis de significância de 90 por cento, 95 por cento e 99 por cento, a metodologia empregada para avaliação remota de baterias para os ensaios de impedância e tensão elétrica e identificou a repetitividade da metodologia da avaliação remota. O resultado da pesquisa foi fundamental para provar a credibilidade do sistema de monitoramento remoto de baterias. A utilização desse sistema ora validado contribuirá para o aumento da confiabilidade dos equipamentos que utilizam sistema de backup, além de redução dos custos de manutenção preventiva. / [en] The present work has the general objective of validating, under real operation conditions, the technique (developed in a laboratorial environment) of remote monitoring of stationery batteries. The development of this MsC dissertation theme was motivated by the contributions that it is expected to give to the Light S.E.S.A. and other companies of the Electric Sector, Oil and Gas, Bank, IT and many others which use stationary batteries in their DC energy supply. Light and CPqD developed together a Research and Development Project named ReD Light-ANEEL 033/2008. This project had as its main objective to increase the reliability of the ancillary services of substations and to reduce their maintenance costs. To reach this target, was developed an automated monitoring system and a remote individual management of all elements that form the batteries bank. The MSc research evaluated, quantitatively, the reliability of the remote metering, performed to the Light’s Baependi substation, which is located in the south zone of Rio de Janeiro City. The methodology applied in this dissertation consists of statistical studies (Hypothesis testing parametric and nonparametric), for comparison of voltage and impedance results obtained in actual operating conditions (Measurements SIMBA-GEBAT) compared to portable measurement. The research has validated, to the significance levels of 90 per cent, 95 per cent and 99 per cent, the methodology used to the remote evaluation of batteries relatively to the impedance and voltage essays, and has also identified the repetitivity of the remote evaluation methodology. The research results were fundamental to prove the credibility of the remote monitoring system of batteries. The use of this system will contribute to increase the reliability of the equipments which use backup systems, besides promoting a cost reduction of the predictive maintenance.

This master thesis is mainly focused on the backup systems and describes each individual backup techniques in detail. Next main point of this thesis, is explaining functionality of IPv4 and FTP, which are closely related to the topic. Outcome is a backup application written in Java language, which is capable of backup files on FTP server or on local/ network storage area. Backup application also allows settings for automatic backup and restoring files from the storage area. Finally there was made a measurment, where were point out advantages and disadvantages of transfer mediums and where was practically shown a logic of creating the backup system. Goal was a creation of multiplatform backup application.
