A rigorous method is introduced to evaluate the overall impact of high-speed railway (HSR) traction loads on a power system using the electrical transient analyzer program (ETAP) platform (Operation Technology, Inc, USA) in this paper. By establishing the detailed models of Network elements and the general traction substation model with the powerful simulation software, this method is capable of handling the large-scale Power systems and the various transformer connection schemes. As the interaction between the power system and the traction power-supply system is considered, the negative sequence components and harmonics effects can be estimated in detail both at the points of common coupling (PCCs) and in public grid. Shanghai-Nanjing intercity railway is taken for an example, in which four power quality indices are simulated and evaluated in different operating conditions. By the comparison of simulation data and measured data, the proposed method is verified to be credible and feasible for the power quality evaluation in practice.
