This study was carried out having as an area for pilot the city of Porto Alegre, RS, where the distributor is responsible for the supply of electricity. The objective of this proposal was to define locations for carrying out a vegetation inventory through a predictive model. From satellite images, the existing vegetation in the distribution network was digitally extracted and, from this, five prioritization factors were associated via Hierarchical Process Analysis (HPA), resulting in an equation with consistency ratio where each factor is given a specific weight, resulting in a priority map. The final model is explained by 36% by the number of power outages, 21.5% by vegetation close to the grid, 21% by the affected population, ...

The main objective of this paper is to show the potential energy existing in landfills, even in medium-sized cities, and that the energetic use of biogas is an accessible alternative to be implemented. For this, it was analyzed two forms of energy generation from municipal solid waste. At the first case it was considered the use of biogas generated in landfills and at the second the waste incineration and for both cases it is presented a study of economic feasibility.

The limits of power quality disturbances that will be monitored are defined by international norm (IEEE 1159). Together with the power quality monitoring system, a power quality assessment was implemented by changing the input variables of the generator in order to restore the standards of the power grid (voltage, current and frequency). The proposed system is a management system, able to identify, quantify and monitor the power quality and can be used as a diagnostic tool for maintenance and a control system for decision-making to reestablish the generation system.

In this context, the gasification of coal is gaining ground because of technological developments, enabling the generation of electricity cleanly and with greater efficiency when compared with consolidated thermoelectric plants. From these premises, this paper will address the national energy demand growth, cost analysis and deployment of IGCC technology comparison with other economic means of generating clean.

The T.P.A. is a two degree of freedom induction machine similar as two linear motors in a unique traction element. To validate the simulations, a real T.P.A. was built with Steel1010 as core material. The magnetic flux was measured by exploratory coils and compared with numerical model software's results. After the validation, the core's material was substituted by SMC Somaloy500which has a high magnetic permeability allied with a higher resistivity than Steel1010and new simulations were made with variation of operating frequencies. The validation's results indicate a correct numerical modelled device with a maximum error of 9,64% and a better response with SMC Somaloy500 for force measurements especially in relative high frequencies up to 120Hz. With Somaloy500 the x-axis force were almost 9 times higher than the Steel1010 as primary core material.

Besides the bad smell and of being forts contaminants, these residues are still collaborators of the greenhouse effect due to the composition of the gases that comes from his decomposition. The high methane concentration in the composition of these gases favors the production of biogas, what can be converted in electric or thermal energy. The objective of this study is to conduct a case study of the implementation of a biodigester in a residential condominium, aiming for the treatment of the residues and use of a produced biogas, minimizing damage to the environment.

However, the thermoelectric plants can bring harm to the environment by the emission of particulate material into the atmosphere. Filters of various principles can be used for containment of those fly ashes, as the cyclone filter. Given the relatively low costs involved this is widely used in a industrial scale and, for having a greater scope for gains in efficiency, will be addressed during this exposed. Is this article, it's contemplated the study of the influence of the system's variables, such as flow velocity of the gas inlet and the diameter of the particles suspended therein. It must be said that this study aims to technical study the filter, not normally considered the economic feasibility of possible changes and implementations; as such factors may serve as a disincentive to finding new methods and technology, which, since then, must be evaluated economically.
