摘　　要：阐述了电气化铁路牵引供电系统的负荷特性。在满足供电要求的情况下,计算分析了牵引变压器容量与各部分电压损失、电力系统短路容量的关系。分别就防止牵引供电系统电压损失和电能质量综合治理问题提出了相应的对策和建议。The load characteristics of the traction power supply system are illustrated for the electrified railways. Under the condition of meeting the power supply requirement, the relationship is analyzed between the traction transformer capacity and voltage loss of variant parts as well as the short-circuit capacity of the power system. Cournter measures and suggestions are forwarded specifically for prevention from voltage loss of power supply system and for the synthetic control of power energy quality.
