Abstract
The generation of wind energy mostly occurs through large turbines and wind towers, however, although this method is established, it does have some negative factors, such as environmental impacts, geographical limitations for its installation, high cost of implementation and questionable power efficiency in certain scenarios. Thus, it is noticed the need to study other models of wind energy generation, thefore this article focuses its research on Ducted Wind Turbine (DWT) systems, which has as its operating principle the capture and redirection of the wind through funnels and tubes, where it is accelerated based on the foundation of the Venturi effect, as soon increasing its efficiency. This technology is proposed to bring solutions or mitigations to the major problems involving the traditional model of wind power generation, so this innovation has important benefits for the renewable energy field. Due to this, the present work aims to carry out a study of the technical and economic viability in the generation of wind energy from channeled wind turbines in the state of Rio Grande do Norte, Brazil, in addition to carrying out a comparison between the system based on conventional Wind Generating Towers and the DWT system. To conduct this analysis, the study was divided into three stages: first, a bibliographic review of wind generation technology and data collection regarding microgeneration of energy in the Brazilian scenario; followed by software simulations of the two power generation systems present in order to obtain information about the amount of energy generated and the cost of each system; and finally, an analysis of the results obtained in the simulations to compare the relevant factors that influence the cost and feasibility of the both systems and identify the scenarios where generation by DWT is feasible, in addition to determining the influence of wind speed on the results of the system efficiency. From that, it is expected to show that, through channeled wind technology, it is possible to mitigate the main environmental problems associated with the usual model and to have a better energy efficiency with a lower cost than the traditional system in relation to the power microgeneration outlook in the region where the system was simulated and analyzed.
