A model of the electric power system of an alternating current railway with account of primary power supply system in the southern part of Iraq

Introduction. The electrification of railway transport is the key component in the modernization of national transport infrastructure. With increasing demand for efficient and eco-friendly transportation solutions, it plays a vital role in meeting these needs. The introduction of electric power systems is becoming a key factor for ensuring sustainable development. Alternating current (AC) railways are characterized by high-energy efficiency, which makes them attractive for large infrastructure projects, especially in regions with developing economies. Goal. This study aims to create a comprehensive model of the AC railway power system in southern Iraq considering the primary power supply system. The model is designed to ensure efficient integration between the railway network and existing energy system in the region with account of such factors as technical specifications of power supply and operational loads. Materials and methods. The study involves developing an enhanced model of the electrical system using the ETAP software, which considers national electrical grid connections, aids in determining the electric load consumed by trains, and compares it with current electricity production levels in Iraq. Results and discussion. The studies provide information on the problems associated with a shortage of electricity production compared to consumption and offer solutions to meet energy needs in southern Iraq. Conclusion. The article centers on securing a reliable power supply for the Baghdad-Basra railway in southern Iraq. Electrification has been a crucial step in modernizing rail transport, promoting regional development, and enhancing the power supply system across vast areas of the country.
