Abstract

The urban railway systems using state-of-the-art technologies for train traffic, safety, traction and rail infrastructure are becoming increasingly widespread in the world. The Moscow Central Circle railroad is an example illustrating their integration into the urban transportation system of a megacity.Development and continuous modernization of such railroad systems during their operation generate new innovative approaches, particularly in the field of electric power supply.Electric traction load on the traction electric power supply system of the Moscow Central Circle railroad has several features explained by prevalence of passenger traffic and frequent changes of operating modes of electric trains. Frequently used regenerative braking determines the statement of the problem of developing a complex of measures to increase the efficiency of traction power supply system measured by the criterion of output capacitance reduction and of energy efficiency indicators’ growth. The use of electric energy storage systems within the traction power supply system can help to solve thementioned problem.The objective of the described research is to assess the efficiency of the implementation of the electric energy storage devices within the system of traction power supply system of the Moscow Central Circle. The research uses the methods of statistical processing of the measurement data and of simulation modelling. Simulation modelling of interaction of electric rolling stock with traction power supply system within the Moscow Central Circle allows to obtain the characteristics of load chart of electric energy storage systems and of bus voltage at sectioning posts, to evaluate the durations of operation cycles in charge and discharge modes, their number and relevant total amount of electric energy per day.The obtained results allow assessing the technical features of various types of electric energy storage devices regarding operating conditions within traction power supply system of the Moscow Central Circle and to determine the economic efficiency of their implementation.
