Aplicação do conceito de geração distribuída a um sistema fotovoltaico residencial

This work presents a study about distributed generation using photovoltaic systems in the context of smart grids. The characteristics of a Smart Grid and the several aspects this concept involves - distributed generation among them - are discussed. There are also examples of equipment, like smart meters, and of national and international projects. The specificities of distributed generation and the rules and standards necessary in this sort of installation are talked through with focus in the solar energy generation method. Regarding photovoltaic systems, the working principles of the panels are presented, along with its main electrical characteristics and the technologies available. Finally there is a study concerning the sizing of a distributed generation system that involves photovoltaic panels in a residential plant. An analysis of the costs and return of investment period is made about the specific case in consideration.

Aplicação e análise da utilização do software Eberick em um projeto residencial popular

Due to new technologies in civil engineering and the competition of the market, the demand for computer programs for the elaboration of structural projects of reinforced concrete is raising in a quick and efficient manner. This paper presents a study based on Eberick, a structural calculation software, and this software was applied to a low cost residence project. By performing structural calculation manually, it is possible to compare and analyze the criteria that Eberick uses for the design and detailing of structural elements like columns, beams and slabs. As the software functionality becomes clear, the engineer will use it careful and safely, exploring all of its resources and advantages

Projeto de condomínio residencial sustentável

It's devised in this work the starting project for the implementation of a residential condominium, focused in the use of technics and technologies to attain sustainability, also stretching to the pilot project for the model house. It's highlighted the methods for exploitation and reuse of water, energy conservation and reduction of environmental impacts. The proposal is to demonstrate the possibility of the use of simple, but effective, ecology technics to make an environmentally sustainable and economically viable project. The main motivators for this work is the growing hydric crisis faced by São Paulo state and the unpaired importance of the sustainability concept as the fundamental term to surmount the challenge of supplying the needs of the current generation without jeopardizing the future of the next generations

Utilização de painéis solares fotovoltaicos no segmento residencial

In order to diversify the global and national energy matrix and reduce harmful impacts on the environment caused by the emission of polluting gases into the atmosphere, the use of clean and renewable energy sources is presented as a good alternative. This work discusses the use of photovoltaic solar energy, a source that presents such characteristics. The photovoltaic system under study is the type distributed connected to the grid, in the residential segment. It is informed of its use in the global and national levels. They are also present their characteristics, electrical and electronic circuits that make up the equipment required for its operation and the design of a system to be installed in a residence

Impacto da redução do nível de tensão na iluminação residencial em uma rede inteligente

In this paper, we will present an overview of the smart grid defining the three main systems that compose it: smart infrastructure system, smart management system and smart protection system. We will conceptualize a functionality of smart management system, the conservative voltage reduction, citing its benefits and its history of application. And, finally, we'll cover a test in which we reduce the nominal voltages on incandescent bulbs, CFL and LED, in the context of residential lighting, and on LED and HPS, in the context of public lighting. The test aims to check whether the voltage reduction adversely affects sources of lighting by measuring the temperature manually with a thermal imaging camera FLIR and illuminance with a LUX meter. The set of power factor, total harmonic distortion, and input power values will be collected automatically through the power quality Analyzer Fluke 345 with a probe Fluke Hall Effect Current. For residential lighting, it was found that both CFL and LED had good performance with the smallest variations in illuminance. Between both, the LED source had the lowest harmonics and the lowest power consumption, on the other hand incandescent bulbs had a bad performance as expected. Public light sources also had a good performance and obtained power factors within the standards, as opposed to the CFL and LED residential sources. The data collected clearly shows the feasibility for nominal voltage reductions. Even with small reductions, there are possibilities of savings which can be passed on to the utilities and consumers
