利用遗传算法解决列车优化运行问题，为了简化问题考虑只有一个牵引和惰性的过程。-Genetic algorithm is used to solve the problem of train operation optimization. In order to simplify the problem, there is only one process of traction and inertia.

牵引供电系统的潮流计算，电力机车等效为PQ负荷，计算牵引网电压分布-Traction power supply system power flow calculation, electric locomotive equivalent PQ load, calculate the traction network voltage distribution
