Abstract
ABSTRACTThe comprehensive power quality (PQ) issues in electrified railways have concerned many research innovations. Many of these topics need a detailed traction power supply system (TPSS) modelling. In response to such a need, a generalized simulation platform is therefore presented. It contains an offline simulation platform and an online monitoring platform, which are developed using MATLAB and LabVIEW software, respectively. The offline platform conducts power and harmonic simulations of the dynamic TPSS over a specific period. It consists of four main subsystems: (1) background utility subsystem, (2) dynamic traction load behaviour subsystem, (3) TPSS solution subsystem, and (4) PQ assessment subsystem. The platform is user-friendly and can be used to model and modify the traction topology (e.g. multiple lines, utility system, and catenary system) and parameters (e.g. different train types, transformers, and infrastructures). Finally, three case studies are presented, and the results show a good performance of the proposed platform.
