The improvement of traction power supply systems of the transport complex is associated with the search for new technical solutions that can improve operational and energy efficiency, reliability and energy security. Electric energy storage systems make it possible to solve these problems. One of the aspects of the application of electrical energy storage systems is the voltage mode at the connection points. The studies of the operating modes of electric energy storage systems on mobile vehicles and stationary objects show the short duration of charge and discharge episodes due to the traction load of electric vehicles. An urgent task is to assess the change in the voltage level of electric energy storage systems in short-term modes when operating in traction power supply systems for various electric energy storage devices. The paper describes a model of the traction power supply system and electric rolling stock containing electric energy storage systems. The change in the degree of charge and voltage depending on their capacity and the time of the applied load is shown. For the conditions of the traction power supply system, the most preferable ones in terms of the minimum voltage level were selected.

The concept of building a traction power supply system with power storage devices provides for their operation to solve the following problems: increasing the transit and carrying capacity, energy efficiency of transportation, reliability of power supply and quality of electric energy. The implementation of pilot projects to solve various problems in the field of traction power supply both in Russia and abroad shows their technical effectiveness.Improving reliability of power supply with the help of storage devices today is considered mainly for options for their use as on-board devices on electric rolling stock or as stationary devices at traction power supply system facilities. Increasing reliability of power supply is achieved through operation of energy storage systems in case of forced or post-emergency modes of operation of traction power supply systems. When solving this problem, it is required to evaluate the voltage level, the change of which is due to the discharge characteristic of the used energy storage device.The objective of the work is to assess the change in the voltage level and energy intensity of the energy storage device used on-board electric rolling stock or as stationary one at traction power supply facilities.Based on the proposed models, the paper assesses the change in the voltage of the energy storage device for the conditions of a short-term absence of voltage in the catenary system using the example of three types of batteries and a supercapacitor. The results obtained in the work allow proceeding to assessment of the performance of electric energy storage systems under various conditions of development of traction load and for different operating modes of the traction power supply system.
