Dimensionamento de um rádio enlace para a ligação entre a subestação móvel de Chongoene e subestação de Chicumbane

Abstract

This report aims to design a microwave radio link for the link between Chicumbane substation and Chongoene Mobile substation, substations located in Gaza province and belonging to Electricidade de Moçambique, E.P. traditional (based on calculations to obtain results) and modern (use of software to obtain results), these methods were useful for calculating the attenuations, availability and unavailability of the microwave radio link system, in these calculations recommendations and equations belonging to the recommendations of the ITU-R (International Telecommunication Union – Radiocommunication Sector). The project presents radio link concepts, the importance of radio links and their application in different areas, it also talks about electromagnetic waves that are the basis for studies of these phenomena, presents the importance of studying the Fresnel ellipsoid in the radio links and steps to be considered for the design of a radio link project. After the sizing, the results were presented, proving the operation of the radio link and the monthly and annual availability. Finally, the equipment to be used in the implementation and budgeting phase of the project was presented.
