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。
Define the soft conflict existing in the running line of the train diagram of high-speed railway, which makes the train unable to operate at the proper power. This problem can not be effectively solved by using the existing train diagram planning method. The mechanism and influence of the formation of soft conflict are analyzed. The simulation of integrated traction power supply and train group is proved to be a good solution to the problem of soft conflict, that is to say, the detection of soft conflict of train operation diagram by traction power supply and the simulation of train based on the detection result Run adjustments, in order to achieve the elimination of the soft conflict. The integrated simulation method not only can solve the soft conflict of high-speed train operation chart, but also can draw the operation strategy of train operation process and solve some difficult problems in simulation calculation of AC traction power supply. Taking one of our country’s high-speed railway lines as an example, this paper verifies the soft conflict resolution method of train operation diagram based on traction simulation.
