2x25KV Railway Feeding System Simulation Database

This dataset corresponds to a paper published in IEE Transactions on Power Systems entitled: "High-Speed 2x25kV Traction System Model and Solver for Extensive Network Simulations"

In this work, a simplified model of a 2x25kV bi-level traction power system for feeding high-speed trains is presented. A Modified Nodal Analysis (MNA) based algorithm for solving the system with and adaptive damping factor is also explained. The main novelties of this work are the inclusion of train protections (over-current and over-voltage) in the model and the development of the MNA solving procedure that increases the stability and robustness of the iterative solving process. Another important feature of the model is that it can be easily adapted to a single voltage feeding systems by deactivation of specific parameters. The accuracy and performance of the proposed simulator is compared and verified relative to the derivative based solvers.
