摘　　要：从城市轨道交通牵引供电计算方法和计算过程入手,着重分析了对牵引负荷计算准确性产生影响的因素,梳理出造成牵引供电计算负荷与实际负荷差异的主要原因。从工程实施的角度提出了减少理论计算结果和实际负荷差异的应对措施。在满足功能需求的前提下,这些措施可尽量降低牵引变压器的安装容量,从而降低变压器的空载损耗,对降低初期投资和运行能耗具有重要意义。According to the calculation method and process of urban rail transit traction power, the main factors that influence the calculation accuracy is mainly analyzed, the reasons for the difference between calculated load and actual traction load are summarized, some corresponding measures are proposed from the project construction point of views. On the premise of meeting the functional needs, these measures will minimize the traction transformer installed capacity and lower the consumption without load, which is meaningful in reducing the initial invest and energy consumption in operation.
