In recent years, attention to construction of high speed electrical railway has been increased. So, attention to high speed AC electrical railway network load flow is very important. Because, by running of load flow the efficiency of feeding system design is determined. In present study, first, the second chapter deals with the existing structures in the electrical railway and selection the best structure for the high speed railway network that can meet the expected needs. In the third chapter, modeling of the components of feeding system and the modeling of train movement is performed that is required for load flow. In Chapter Fourth, three solution methods (Gauss - Seidel, Newton - Raphson, and backward - forward) are used in load flow calculations and their equations and algorithms are investigated. In Chapter fifth, the results of the train movement simulator calculations and electrical network simulator are analyzed and the results of the three aforementioned solution methods are compared in detail. the final chapter deals with concludes of simulation results and offer suggestions. Based on the simulation results, Newton - Raphson method was more efficient in terms of response accuracy parameters and number of repetitions required for convergence to reach the final answer and backward - forward method in terms of time parameter required to calculate the final response than other proposed methods.
