摘　　要：铁路机车在牵引网中运行会引起线路的电压波动,我国西部地区存在大量长上坡与长下坡线路,机车在这些线路上运行引起的电压波动更大,可能会影响其安全稳定运行。为减小牵引供电网的电压波动,提出了一种牵引网电压综合补偿控制方法。首先分析了机车运行时产生的电压波动对牵引供电系统的影响,将列车作为恒定功率模型进行迭代得到实时的节点电压矩阵;然后研究了牵引网电压综合补偿控制方法的拓扑结构及其工作原理,提出了牵引网电压综合补偿控制方法的控制策略;最后进行了仿真分析。理论分析和仿真结果表明,牵引网电压综合补偿控制方法具有实时性、可控性和可行性,能够实时保证机车在不同的工况下运行时,其电压始终处于满额功率运行状态,有效解决了电压波动问题。Railway locomotive operation in traction network will cause voltage fluctuation of the line.In the northwest of China,there are a lot of long uphill and long downhill lines,the voltage fluctuation caused by locomotive operation on these lines is great,which may affect the safe and stable operation of the locomotive.In order to reduce the voltage fluctuation of traction power supply network,a comprehensive voltage compensation control method of traction power network is proposed.Firstly,the influence of voltage fluctuation on the traction power supply system during locomotive operation is analyzed,and the real-time node voltage matrix is obtained by iterating the train as constant power model.Secondly,the topology and working principle of traction network voltage comprehensive compensation control method are studied,and the control strategy of the traction network voltage comprehensive compensation control method is proposed.Finally,the simulation analysis is carried out.Theoretical analysis and simulation results show that the traction network voltage comprehensive compensation control method has real-time,controllability and feasibility,which can ensure that the locomotive voltage is always in full power operation state under different working conditions in real time,and effectively solve the problem of voltage fluctuation.
