Abstract: Recently, the demand for electricity in Iraq has increased; therefore, there is an increased demand for generating and transmitting electrical power. Furthermore, Iraq’s electricity grid is interconnected with neighboring countries to supply electricity and compensate for the shortage in energy production. This work investigates the reliability assessment of secondary power transmission systems in the Iraqi Electricity Power Distribution Network (IEPDN). A fault tree analysis (FTA) technique based on fault tracing paths was applied to assess the reliability of the secondary power system in Iraq, due to its ability to perform a computation for all failure probabilities of the network components. The reliability of the Northern Secondary Power System (NSPS) and the Southern Secondary Power System (SSPS) was calculated based on the fault probability index. Findings indicate the reliability of both the Northern and Southern secondary power systems. Therefore, the Southern and Northern power grids can be used to connect Iraq with neighboring countries to meet Iraq’s energy needs.
