摘要:
随着铁路向更复杂线路条件、更高速度、更高安全性、更高可靠性和更智能化的方向发展，作为牵引列车唯一的动力来源，牵引供电系统面临的外部电网供电能力不足与冲击性负荷随机波动的平衡问题、服役环境恶劣与高供电可靠性之间的匹配问题、多元新能源灵活接入与实际节能减排效果之间的优化问题等将更加突出。针对电气化铁路牵引负荷的特殊性，本文结合目前正在开展的成渝中线项目，深入研究速度400 km/h及以上高速度铁路牵引负荷需求与牵引供电系统技术的适应性，进一步研究提高牵引供电能力、延长供电范围、减少速度损失的供电新方式，解决速度400 km/h及以上高速铁路牵引供电系统的技术难题，为工程设计方案的优化奠定基础。
Abstract:
As the railway is developing into a system of more complex line conditions with the prospect of higher speed, safety, reliability, and more intelligence, the traction power supply system, as the only power source of traction train, is facing more and more prominent problems, such as the balance between making up the insufficient power supply capacity of the external power grid and overcoming the random fluctuation of impact load, the requirement of matching the high power supply reliability to the harsh service environment, and the optimization between providing flexible accesses of multiple new energy sources and improving the actual energy saving and emission reduction effects. In view of the particularity of traction load of electrified railway, combined with the ongoing Chengdu-Chongqing Middle Line Project, this paper made an in-depth study on the adaptability of the traction power supply system technology to the traction load demand of high-speed railway with a speed of 400 km/h and above, and further on the new power supply modes to improve traction power supply capacity, extend power supply range and reduce speed loss for the purpose of solving the technical problems of traction power supply system of high-speed railway with a speed of 400 km/h and above, and laying a foundation for the optimization of the engineering design scheme.
