摘要:
市域轨道交通的车站间距、设计速度目标值等介于干线铁路和城市轨道交通之间，其供电制式的选择直接影响到所建线路的技术和建设标准。不同的供电制式具有不同的特征及故障处理方式，这对市域轨道交通的运营服务水平和可靠性会产生影响。结合不同牵引供电制式的技术特点，对市域轨道交通牵引供电制式选择进行了分析。并从弓网关系、供电故障影响、设备可靠性等方面开展探讨，提出了市域轨道交通牵引供电制式的优化方案。 交流牵引供电与刚性接触网的组合，应成为市域轨道交通隧道区段牵引供电制式的发展方向之一。
Abstracts:
The station spacing and targeted speed design of urban regional rail transit is between those of the trunk railway and urban rail transit，the selection of power supply mode directly affects the technical and construction standards of the built lines. Because of different characters and fault handling methods，different power supply modes ultimately affect rail transit operation，service level and reliability. Based on the technical characteristics of different traction power supply systems，the selection of traction power supply system for urban regional rail transit is analyzed from angles of pantograph catenary relationship, impact of power supply failure and equipment reliability，an optimized traction power supply mode for urban regional rail transit is proposed，the combination of AC traction power supply and rigid catenary is regardedas the development trend of traction power supply mode for urban regional rail transit.
