Redimensionamento de linha de 110 kv (cl3a) que interliga as subestações de Macia e Dzimbene na Provincia de Gaza.

Abstract

This work is the result of a problem detected during a professional internship at EDM-DTSU, which consists of the need to increase the power transmission capacity of line CL3A of the southern transmission network, which connects the Dzimbene and Macia substations in the province of Gaza. To solve the problem, the installed capacity was surveyed as well as the maximum loads recorded on the line. Based on the load, the power to be transported was determined, followed by determining the line's service current. The service current led to the conclusion that the best alternative between building a new line or doubling the section of the existing one was to replace the Dove conductor with a capacity of 500 A with a Lisbon conductor, which increased the line's capacity to 1200 A. This increase in capacity makes the southern transmission system more reliable, especially in the provinces of Gaza and Inhambane, since their power supply is guaranteed by the CL3 A line.(TRADUÇAO NOSSA)
