Abstract All the nodal voltages are the unknowns to be solved in the system of nodal voltage equations of electric railway traction network. There are substantial parallel elements in the network, which makes the dimension of the system of equations high and cost much time to calculate. A power flow Algorithm was designed for one-port and multiple-port AC electric railway network in this paper based on multiple-port Thévenin equivalence. It decreases the dimension of the iterative system of equations, reduces the calculation time, and increases the calculation efficiency. Verification was conducted with an example. It was also discussed in the aspects of the change of the train voltage during the iterations and multiple solutions.

Key words： Electric railway traction network power flow multiple load port Thévenin equivalence multiple power flow solutions
