| Abstract: | This study discusses design of city metro power supply system and key technology for mountainous areas considering the schemes for train braking energy feedback, parallel supply connecting the upward and downward the traction network catenaries, laying of special section ring cables, installation of special section catenaries, as well as high soil resistivity area grounding setting according to Guiyang Rail Transit line 1. Some of these design schemes achieved the desired results with the trial operation of line 1. This article is expected to provide some references for the subsequent design of subway power supply for mountainous cities n. |
