This study presents a modelling and simulation method for the analysis of short‐circuits in 1 × 25 kV railway traction systems (RTSs). First, the authors developed models of major components and a full‐scale model of a RTS. The component models developed in this study include a specific Le Blanc traction transformer and an overhead catenary system. The models are represented using corresponding coupling‐free equivalent circuits to facilitate implementation using software packages MATLAB ® /Simulink ® . The short‐circuit fault simulation of a RTS was conducted on a personal computer operating with MS Windows 7 ® . Field testing data was used to verify the simulation results. The modelling and simulation technology developed in this study provide a valuable reference for power engineers involved in the planning, design, and operation of a railway traction network.
