O trabalho desenvolvido nesta dissertação decorreu no âmbito de estágio, realizado na EDP
– Distribuição SA, no departamento de Projetos e Construção, no Porto.
Os objetivos propostos ao estagiário consistiram, primeiramente, no desenvolvimento de um
projeto de uma linha aérea de alta tensão de 60 kV, com início na subestação de Caniços, em
Santo Tirso, e término na subestação de Areias, em Vila Nova de Famalicão. Para a segunda
parte do trabalho foi proposta a realização de um projeto de uma linha subterrânea, que
interligará o Posto de Corte da Prelada e a subestação da Boavista, seguido de um caso de estudo
referente à viabilidade técnica e económica do método de ligação de blindagens à terra, de um
cabo subterrâneo, denominado Cross-bonding, comparativamente ao método mais usual, o
Both-ends.
Ambos os projetos realizados, regeram-se pelo Regulamento de Segurança de Linhas
Elétricas de Alta Tensão, cumprindo todas as diretrizes referentes às localizações dos apoios,
às distâncias mínimas exigidas, para as estruturas e o seu meio envolvente, bem como, para os
condutores da linha, no caso de um projeto de uma linha aérea e, também, todos os requisitos
técnicos necessários à implementação de uma linha subterrânea, como a constituição dos cabos
a utilizar e a sua forma de implementação no solo.
The work developed in this dissertation was carried out at an internship at EDP - Distribuição SA, in the Department of Projects and Construction, at Oporto. The objectives proposed to the trainee consisted first of all in the development of a 60 kV high voltage overhead line project, starting at the Caniços substation in Santo Tirso and ending at the Areias substation in Vila Nova de Famalicão. For the second part of the work it was proposed the development of a project of an underground line, which will interconnect the Prelada Cut Station and the Boavista substation, followed by a case study regarding the technical and economic feasibility of the method of connection of shields to ground, of an underground cable, called Cross-bonding, compared to the most usual method, Both-ends. Both projects obey to the High Voltage Power Line Safety Regulations, complying with all the guidelines regarding the locations of the supports, the minimum distances required, for the structures and their surroundings, as well as for the line conductors, in the case of an airline design, and also all technical requirements for the implementation of an underground line, such as the design of the cables to be used and the way they are implemented in the soil.
