MODELLING AND VERIFICATION OF SIMULATION RESULTS IN COMPUTER AIDED ANALYSIS OF ELECTRIC TRACTION SYSTEMS

Modern electric traction systems require efficient tools for analysis, especially in the area of new technology, when modern technical solutions are being introduced. In order to make the elements of electric traction systems compatible, even at the design stage of the project, it is required to foresee the possible operating conditions of the locomotives,power supply, or signaling equipment. It is especially important when new technology is to be applied on an existing railway line with old-type infrastructure. This case was observed on Polish State Railways, where main railway lines were constructed 20-30 years ago and now face modernization requirements for high-speed high-power locomotives. Different models of electric traction vehicles, traction substations, catenary, signaling, and control circuits exist and are widely used. Because of the complexity of the phenomena and mutual dependencies between subsystems, the models differ in the simplification assumption and in different purposes of their usage. One of the critical points in their application is the verification of the models, which could allow making the models more coherent with the systems. This paper presents the derived simulation models of the elements of the electric traction subsystems such as rectifiers, traction vehicles, and models of direct current (DC) electrified railways. Verification of the models with the measured values in real systems is also presented. In addition, the paper contains the results of the application of the models in research works performed for Polish State Railways.
