地铁和电气化铁路的牵引供电系统比较研究

随着经济与科技发展,我国地铁网络规模在空间上不断扩大,提升了社会的整体运行效率,其中,牵引供电系统的发展成熟及其广泛应用直接促进了地铁和电气化铁路的发展进步。与此同时,牵引系统的安全性和稳定性也受到越来越多的关注,因其一旦出现故障将会带来重大的生命财产损失。为了促进牵引供电系统更加安全稳定地应用,对地铁和电气化铁路牵引供电系统的工作原理、运行方式和牵引供电保护方式进行了比较分析,希望能为牵引供电系统的应用提供理论与实践起到一定的借鉴作用。

With the development of economy and technology, the scale of China’s metro network has been expanding in space and improving the overall operation efficiency of the society. The development and maturity of traction power supply system has di-rectly promoted the development and progress of Metro and electrified railway. At the same time, the safety and stability of traction system is also attracting more and more attention, because once it fails, it will cause significant loss of life and property. In order to promote the safe and stable application of traction power supply system, the working principle of the traction power supply system of metro and the electrified railway traction power supply operation mode and protection mode are analyzed, hoping to provide theory and practice plays a certain reference role for the application of traction power supply system.
