Modern principles of electrification design of the Southern Iraqi railways

Abstract

Introduction. Railway transportation plays a key role in the national economy as the primary means of moving goods and passengers between regions with minimal costs. It efficiently transports large volumes of cargo over long distances, making it attractive to corporations. Additionally, it is environmentally cleaner compared to other modes of transportation, contributing to sustainable development. Railway infrastructure also fosters regional development by providing access to employment, education, and healthcare. Technological advancements improve safety and reliability.Goal. One important focus of this article is the transformation of the 600-kilometer-long southern line of the Iraqi railways, stretching from the capital Baghdad in central Iraq to the far south, into an electrified railway system.Materials and methods. For the successful implementation of the electrification project, researchers utilized an assimilation system created using ETAP software. This powerful tool enables the determination of electric load values consumed by electric trains and accurately models the entire electrical infrastructure.Results and discussion. During the research, valuable information about complex and unified alternating current systems, as well as network systems for calculating loads on traction distribution wires, was discovered. This allows for the optimization of the system's operation, ensuring smooth and efficient movement of electric trains along the entire route.Conclusion. Based on the conducted research, it can be concluded that the transition of the southern line of the Iraqi railways to an electrified system is a significant milestone for the country, reflecting its commitment to developing a modern and sustainable transportation infrastructure. This also confirms Iraq's readiness to implement advanced technologies in the railway sector, contributing to further development and economic prosperity of the nation.
