Title: Improvement of the Voltage Profile of Atbara-Port Sudan 220 KV Transmission Line
Author: Ahmed, Ehssan Abdelgoum Osman Seed
Abstract: The aim of this research is to improve the voltage profile of Atbara –Port Sudan 220kv transmission line. This line has witnessed considerable voltage drops leading to a decrease in the voltage at receiving ends in Port Sudan to about 20% below the rated voltage which constitutes a very serious technical problem.The technique used to improve the voltage profile is series compensation which involves the connection of capacitor in series with the line resulting in reduced line reactance and hence reduced voltage drop along the line. The study was carried out using ETAP program and the results showed that by the connection of a capacitor of -143 ohms reactance, the voltage at Port Sudan was improved from 177 KV to 224 KV which is a very acceptable result.
