Model and Algorithm for Traction Power System Simulation of Urban Rail-line

The article presents a brand new model and algorithm(RS) applicable in traction power system simulation of urban rail transportation. The model RS concludes a consistent algorithm to be realized by computer easily for different kinds of power systems of the subway and light railway traction. RS has wide adaptability and high accuracy satisfying engineering requirements with reasonable hypothesis. The model can not only provide analytical data for demonstrability and design for the construction and reconstruction of the urban rail transportation, but also calculate and check the technical parameters of the power traction substation. The computation result of the simulation software has been successfully applied in designing, testing, and optimizing power systems of the subway and light railway traction.
