摘要:
［目的］目前，我国市域铁路仍没有应用CTCS-3(中国列车运行控制系统3级)的案例。为扩展CTCS(中国列车运行控制系统)在市域铁路中的应用，应对CTCS-3在市域铁路的应用进行探讨。［方法］分析了现有市域铁路的特点及CTCS制式在市域铁路应用的现状，提出了CTCS-3在市域铁路应用的技术方案。分析了CTCS-3在市域铁路的适应性，对应用于市域铁路的CTCS-3的技术方案提出了优化建议。［结果及结论］与CTCS-2(中国列车运行控制系统2级)相比，CTCS-3(不以CTCS-2为后备)在市域铁路中具有更好的适应性，其在牵引供电制式适应性、保护区段设置方式、与其他轨道交通制式互联互通等方面均具有优势，信号工程成本也较低。
Abstracts:
［Objective］ At present, there is still no practical case of using CTCS 3 (Chinese Train Control System Level 3) in city railway in China. The application of CTCS-3 system in city railway should be explored to expand its application in urban railway. ［Method］ The characteristics of the existing city railway and the current status of CTCS application in city railway are analyzed. The technical scheme of CTCS-3 application in city railway is proposed, its applicability is analyzed, and the optimization proposal for its application scheme is put forward. ［Result & Conclusion］ Compared with the CTCS-2, the CTCS-3 (without CTCS-2 as backup) has better applicability in city railway in terms of its advantages in traction power supply system adaptability, protection section setting method, interconnection with other rail transit systems, and lower signalling engineering cost.
