Improving the energy efficiency of railway transport by using mobile devices of transverse capacitive compensation

Abstract

The authors of the article propose the use of mobile devices for transverse capacitive compensation of reactive power to improve the energy efficiency of railway transport. The possibility of reducing the existing inter-train intervals of heavy trains along the section of the Achinsk-I–Chernorechenskaya railway of the Achinsk power supply distance is considered when using transverse capacitive compensation of reactive power at the Tarutino sectioning station to increase the available capacity of the railway section under consideration. The calculations were verified in the KORTES software package. The calculation performed in the KORTES software package shows that when using mobile devices for transverse capacitive compensation of reactive power on the Krasnoyarsk Railway, it allows to increase energy efficiency and increase the throughput of the calculated section of the Achinsk power supply distance Achinsk-I–Chernorechenskaya. The use of mobile reactive power compensation devices makes it possible to increase the voltage level on the current collector of electric rolling stock by 1,05–1,33 kV and ensure the movement of freight trains of increased mass (up to 7,100 tons) in an even direction with an inter-train interval of 14 minutes. When the second power transformer is turned on at the Achinsk-I and Chernorechenskaya traction substations, the voltage on the electric rolling stock current collector increases by 2,43–2,65 kV, and the inter-train interval decreases to 8–9 minutes. The authors of the article believe that the results of the calculation can be useful for optimizing the operation of railway systems and increasing their efficiency in general.
