Lithium ion battery application in traction power supply system
2014 16th International Power Electronics and Motion Control Conference and Exposition, 2014Technology development has been promoted aiming for an environment-friendly traction power supply system for railways. Among other things, a stationary energy storage system using lithium ion batteries for hybrid cars has been put into practical use since 2007. This device temporarily stores regenerative power generated from an train when it is stopped

Composite Load Equivalent Modeling of Traction Power Supply System
2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES), 2021In recent years, China's high-speed railway from zero to one, from weak to strong, has achieved a leapfrog development. However, the access of a large number of electrified railways is a further challenge for the safety, stability and economy of the power grid, but the current research on the composite load characteristics of traction substations is ...

A hybrid railway power conditioner for traction power supply system
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013Co-phase traction power supply system was proposed for supplying the long-distance electrified railway without neutral sections. However, a railway power compensator (RPC) needs to be installed in each substation together with the traction transformer for improving the power quality.

Wide Area Protection System for AT Traction Power Supply
2021 International Conference on Control Science and Electric Power Systems (CSEPS), 2021All-parallel AT traction power supply has become a commonly used power supply mode in China high-speed railway. The current relay protection system for the all-parallel AT traction power supply mode has the defect that it will cause comparatively wider area and longer time of power outage.
