International Journal of Engineering and Information Systems (IJEAIS)   Year: 2020 | Volume: 4 | Issue: 12 | Page No.: 117-127 Enhancement of Atbra -Port Sudan Transmission Line Using SVC and TCSC Mohammed Elmubarak Adam, Mohammed Altom, Rami Alsir, Bahaaldeen Mohammed , Abdalla Naeem , Diaeldin Zayan Abstract: Due to the ever increasing demand for power, economic and environmental constraints that limit the expansion and restructuring transmission networks, the transmission lines are prone to be operated under harsh conditions, and power systems to operate near peak limits. This research investigates different scenarios to enhance the power transfer capability of (Atbara-Port Sudan) transmission line as one of the national grid problems. Simulation was conducted using NEPLAN software, based on data given from Load Dispatch Center (LDC) in Sudan. National grid has been studied in peak and off-peak cases, to clearly represent the issue. All the results presented in comparison form to figure out the best case. Power transfer capability of (Atbara-Port Sudan) enhancing up to 50% of existing load by using TCSC beside SVC installed in Port Sudan.
