牵引供电扩能系统仿真研究

改善电气化铁道牵引供电能力不足的有效措施之一是进行牵引供电扩能改造,应用综合补偿技术是牵引供电扩能的最佳方法.但其影响因素较多,且时变性和相关性强,不易建立精确的数学模型.本文采用基于列车牵引计算的仿真方法,针对增设不同的扩能补偿设备,结合半定量分析方法时补偿设备的安装位置和投切容量等参数选取、有效控制策略的选择等建立了牵引供电扩能仿真系统,通过分析列车的运行工况来评价投入不同补偿设备所达到的扩能效果,系统的应用结果表明该仿真模型是行之有效的.

Research on the Simulation of Capacity Expansion of Traction Power Supply

The traction power supply expansion is one of the effective measures for improving the capability of the traction power supply for the electrified railway. Application of an integrated traction power supply compensation technique is the best way to capacity expansion. However, it has more influence factors,the time-varying and relevance is strong,and it is not easy to establish the precise mathematical model of sys- tem. Based on the train traction calculation and additional expansion equipment, the simulation of capacity expansion of traction power supply has been established. The system is simulated by using of semi-quantitative method to select limited parameters and effective control strategy. The effect of the equipment is analyzed and evaluated by the results of the train. The application of the system shows that the simulation model is feasible and effective.
