摘要:
针对部分城市轨道交通线路存在长大区间且难以设置区间牵引变电所的工程难点，从优化变电所自身设计角度，提出了在区间两端牵引变电所内设置两套互为备用的牵引供电设备以增加其牵引供电能力的实施方案，同时对基于该方案下的变电所运行方式切换、保护配置、供电可靠性等方面进行了分析，形成了一套切实可行的设计方法，可有效解决区间内无法加设牵引变电所带来的长距离牵引供电能力不足的问题。
Abstracts:
Aiming at the engineering challenge that some urban rail transit lines have long-large intervals where the set-up of interval traction substations is difficult, from the perspective of optimizing substation design, an implementation scheme is proposed, in which two sets of mutually standby traction power supply equipment are set up in the traction substations at both ends of the interval to increase traction power supply capacity. Moreover, operation mode switching, protection configuration and power supply reliability of the substation in this scheme are analyzed, and a set of practical and applicable design methods is formulated, which can effectively solve the problem of insufficient traction power supply in long distance due to the inability of adding extra traction substations within the interval.
