摘　　要：定义存在于高速铁路列车运行图运行线间的使列车无法在适当功率下运行的软冲突问题,该问题使用既有列车运行图规划方法难以有效解决。分析软冲突形成的机理及其影响,论证牵引供电与列车群一体化仿真计算方法能较好解决软冲突问题,即利用牵引供电计算实现列车运行图软冲突的检测,基于该检测结果进行列车仿真运行调整,从而实现对软冲突的剔除。一体化仿真方法不仅能实现高速列车运行图软冲突的疏解,同时也能得出列车运行过程的操纵策略,并解决了交流牵引供电仿真计算中的某些难点问题。选用我国某一高速铁路线路为例,验证基于牵引仿真的列车运行图软冲突疏解方法。The soft conflict occurring between running lines in the highspeed train diagram to make trains una ble to run at the appropriate power was defined, which was found hard to solve the soft conflict problems with the existing methods of formulating the train diagram. The mechanism and influence of forming soft conflicts between highspeed train running lines were analyzed. It was demonstrated that the method of integrated simu lation of traction power supply and train group operation could better solve the soft conflict problems, namely, traction power supply calculations were used to detect soft conflicts of the train diagram and on this basis train operation simulation adjustment was made to get rid of the soft conflicts . The proposed method proves effec tive in rejecting soft conflicts of the train diagram, provides the control strategy of the train operation process , and solves some difficult problems in simulation calculation of AC traction power supply. Finally a train dia gram was formulated and based on adjustment of soft conflicts for a real highspeed railway line in China.
