Comparison of Traction Substation Topologies for AC 25kV Electrical Railway

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
The paper is focused on topologies of traction substations for AC railway traction system especially for 25kV, 50Hz (respectively 60Hz). The current progress of power electronic field of study allows to use semiconductor converters as a part of distribution power grid (i.e. for HVDC), for traction issue but also for traction substations. This expansion

System for converting the DC traction substations into active substations

2015 9th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2015
This paper is concerned with the possibilities of transformation the DC traction substations with uncontrolled rectifiers into active substation, being able to ensure both the braking energy recovery and active filtering function. There are a lot of approaches on the management of regenerative braking energy, most of them based on energy storage ...

Implementation of an Active Regeneration Unit in a traction substation

2014 16th European Conference on Power Electronics and Applications, 2014
Abstract This paper describes the practical implementation of an Active Regeneration Unit (ARU) at two locations of the metro network in Rotterdam. Surplus braking energy that cannot be used by other vehicles is supplied back into the public grid.

Application of Case-Based Reasoning for Traction Substation Design

2008 International Conference on Computer Science and Software Engineering, 2008
The paper analyzes traction substationpsilas structure and spare parts, product main model. It mainly studies the application of case-based reasoning (CBR) in the design of traction substation. The application adopts architecture and object-oriented presentation to represent productpsilas structure and case base. It adopts level-2 indexing to determine
