摘　　要：为研究牵引网电压的波动及牵引能耗受列车运行的影响,分别在列车各运行状态下进行受力分析,绘制列车运行曲线,在此基础上,以5个车站、3个牵引变电所为模型,推导双线列车运行下的网压方程,并通过高斯赛德尔迭代法进行网压方程的潮流计算,得出了牵引网压波形及牵引能耗,最后分析了列车运行对牵引网电压及牵引能耗的影响,为列车运行优化及制动能量利用研究提供借鉴。In order to study the impact of fluctuation of traction network voltage and the traction energy consumption on train operation,force analysis is conducted under various operating states of the train,and train operation curves is drawn,and on this basis,5 stations and 3 traction substations are taken as the models for derivation of the network voltage equation under the operation of double track trains,and Gaussian Seidel iteration method is used for power flow calculation of the network voltage equation,and the traction network voltage waveform and traction energy consumption are obtained.Finally,analysis is made for the impact of train operation on traction network voltage and traction energy consumption,providing reference for optimizing train operation and study on the utilization of braking energy.
