Análise da transmissão de energia elétrica sem fio usando micro-ondas para Região dos Campos de Cima da Serra em uma área de difícil acesso

Abstract

This work analyzes the feasibility of a wireless electric power transmission system in the rural area of Vacaria, Rio Grande do Sul, characterized by difficult access and a lack of basic infrastructure. The proposal employs a Cassegrain parabolic antenna and a Magnetron generator for microwave power transmission, offering a solution to serve remote communities. The approach includes theoretical analyses and detailed simulations, evaluating parameters such as gain, directivity, and propagation losses. The Cassegrain antenna demonstrated good beam concentration, radiation control, and a gain of 35 dBi in the main lobe, ensuring efficient energy transfer, while its configuration showed significant attenuation in the side lobes, reducing losses and interference. The Magnetron generator, operating at 3 GHz, provided the stability and power required for the system. Simulation results indicate that for a transmission power of 10 kW, the received power was approximately 3 kW, reflecting the system's efficiency under real conditions, considering factors such as atmospheric absorption, obstructions, and inherent microwave beam losses. The configuration proved functional and effective for applications in hard-to-reach areas, demonstrating its suitability for meeting the needs of isolated communities. [resumo fornecido pelo autor]
