Calculation of the parameters and performance indicators of the power storage system in areas with regenerative braking of the electric rolling stock
The prospects for solving problems of increasing the capacity and energy efficiency of the traction power supply system are associated with the appearance of regulated devices. This type of device includes power storage systems that affect the load capacity indicators, the level of energy efficiency and the reliability of the traction power supply system. The performed calculations show that various conditions for the use of regenerative braking on the site affect the conditions and performance of storage systems. The main effects when using regenerative braking are manifested in a decrease in the filling coefficients of the graph and the charging characteristic, the predominance of charge in the graph and degree and an increase in the required total energy intensity. The change in the main statistical performance indicators when using the power storage system in various conditions of the regenerative braking are shown, for example, one of the railway sections.
