The operation simulation of energy storage systems on the double-track sections of direct current railways

The article deals with the research in the field of application of energy storage systems to in-crease throughput and carrying capacity on railway sections. The studies carried out by Russian and foreign researchers reveal various aspects of the application of energy storage systems in the energy supply systems of transport. In relation to the traction energy supply system the article shows the method of calculation of energy indicators, including those for the energy storage system, as well as algorithms of calculation and operation of the energy storage system at the sectioning station. The research demonstrates how the energy storage system influences the voltage level on the current collector of the electric rolling stock and the minimum inter-train intervals. The calculation results determine the threshold voltages and the charging characteristic, which makes it possible to maintain the energy storage system state of charge at the target level. The parameters of the energy storage system are defined. The reduction of the minimum inter-train interval is shown on the example of one of the double-track railway sections. It leads to the reduction of the payback period of the project on the introduction of energy storage systems.
