Desenvolvimento e análise de um micro aerogerador de baixo custo para aplicação em ambiente rural

Abstract

Wind energy is a renewable and well-known source. Although it is currently little used in relation to other energy sources, such as: Use of coal, oil and natural gasit. Wind energy is of great importance, mainly in the context of reducing greenhouse gases, since the use of a clean energy source (without pollutant emissions) when replacing the use of a non-renewable source (with pollutant emissions) implies a reduction in the rates of greenhouse gas emissions. According to the Brazilian Association of Wind Energy (2018), Northeast represents 85% of the supply for the Brasil. Pernambuco stands out for having a wide territory on the coastline and in the interior of the state, a region of high elevation due to its location on the Borborema plateau, a region of great potential due to the strength of the winds being high at high altitudes. Knowing the potential of the region for applications in the sense of wind generation, the purpose of this work was to discuss ways of taking advantage of this wind potential with the application of a prototype of a micro wind turbine that had the characteristics of having: Low cost associated with the elaboration of the project, low manufacturing complexity, use of recyclable materials and a practical application to help reduce electricity costs for small rural producers. For the execution of the work, still in the planning phase, theoretical data of the behavior of the wind in the region where the prototype would be applied were collected, in addition to stipulated values of theoretical power generated by the turbine from the coverage area of the turbine blades. In addition to the production and theoretical analysis of data, this work deals with the financial and social gains associated with the application of a micro wind turbine in small rural communities. In addition, the work presents the total budget of the project and its possible practical applications. Presenting satisfactory results in relation to the average power generated and turbine efficiency, in addition to the 80% lower cost of the prototype in relation to commercial wind systems with the use of reused material.
