一种新型牵引供电网构想

A New Traction Power Grid on Main Railways

在深入分析我国电气化铁路单相工频交流牵引供电网目前存在的主要问题的基础上,提出了用高压直流牵引供电网集中解决这些问题的构想,较系统地阐述了这种牵引供电网电压等级的选择、整个供电系统的基本结构、卓越的技术经济性能、面临的历史条件、需要解决的关键问题等。初步得出了这种牵引供电网比现在干线铁路上使用的任何一种牵引供电网性能更好,而其建设投资更少的结论。

This paper deeply analyzes the main problems with the current traction power grid in our country and puts forward the relevant solution by use of the high voltage DC traction power grid. Regarding the newly proposed system, selection of the voltage level, the basic structure, outstanding technical and economical performance, current conditions, and key problems awaiting to be solved are described systematically. The preliminary conclusion is drawn that the high voltage DC traction power grid is better in performance and lower in cost as compared with any other type of traction power grids which are being employed on the mair railway lines.
