Abstract(s)
A presente dissertação de mestrado tem como principal objetivo, o desenvolvimento de um projeto de uma linha aérea de alta tensão 60 kV, efetuando-se o estudo das metodologias, cálculos e dimensionamentos de acordo com as diretrizes da EDP-Distribuição, do regulamento de segurança de linhas elétricas de alta tensão (RSLEAT) e utilizando critérios de projetista.
Foi ainda desenvolvida uma aplicação implementada em ambiente de simulação Matlab, com o intuito de sistematizar o cálculo e projetos futuros. Esta aplicação permite também efetuar o estudo do comportamento das flechas das catenárias em função da variação da temperatura ambiente e do respetivo comprimento de vão. Estes modelos foram sustentados com base num projeto real, o qual consiste numa linha aérea de transporte de energia elétrica com um comprimento de 16.1 km, uma potência de transporte de 38 MVA e com uma tensão de transporte de 60 kV. Este projeto foi estabelecido tendo por base no regulamento de segurança de linhas elétricas de alta tensão, cumprindo todos os requisitos técnicos relativamente às localizações dos apoios, distâncias mínimas exigidas para as estruturas e para o meio envolvente.
The main objective of this master's thesis is the development of a high-voltage 60 kV overhead power line project, carrying out its study of methodologies, calculations and performing dimensioning according to EDP-Distribuição guidelines, high-voltage power line safety regulation (RSLEAT) and using designer criteria. An application was also developed and implemented in Matlab simulation environment, with the purpose of systematizing the calculation and future projects. This application allows the study of the behaviour of overhead catenaries sags, according to the variation of the ambient temperature and the respective span length. These models were supported based on a real project, which consists of an overhead power line with a length of 16.1 km, a transport power of 38 MVA and a transport voltage of 60 kV, this project was established based on the safety regulations for high voltage power lines, fulfilling all the technical requirements regarding the locations of the supports, minimum distances required for the structures and the surrounding environment.
