为了给同相供电系统牵引变压器容量选择提供理论依据,在既有异相牵引供电系统设计方法的基础上,分析了同相供电系统馈线电流与既有牵引供电系统馈线电流的差异,并针对既有线改造和新线建设两种情况提出同相供电系统牵引变压器容量设计方法。通过既有线和新建线路实现同相供电系统两个算例,说明新建线路和既有线牵引变压器容量可降低1~2个容量等级,并有效提高牵引供电系统运行经济性。
為瞭給同相供電繫統牽引變壓器容量選擇提供理論依據,在既有異相牽引供電繫統設計方法的基礎上,分析瞭同相供電繫統饋線電流與既有牽引供電繫統饋線電流的差異,併針對既有線改造和新線建設兩種情況提齣同相供電繫統牽引變壓器容量設計方法。通過既有線和新建線路實現同相供電繫統兩箇算例,說明新建線路和既有線牽引變壓器容量可降低1~2箇容量等級,併有效提高牽引供電繫統運行經濟性。

To provide a theoretical foundation for selecting traction transformer capacity in co-phase traction power supply system,the difference between the feeder current of the co-phase traction power supply system and existing traction power supply system was analyzed. The design methods of traction transformer capacity for two cases of existing railways electrification and new railways construction were proposed. The results of case study show that the proposed methods can decrease 1-2 capacity grade of traction transformer for both cases and the economy of traction power supply system is significantly improved.
