铁路应急电源设置方案及运行仿真分析

Scheme for Setting up of Railway Uninterrupted Power Supply and Analysis of Operation Simulation

针对现有铁路大型客站在防灾设计方面存在的问题,选取通过设置应急电源的方案来提高铁路电源线路供电的可靠性,并基于武广客运专线一段长78.3km的全电缆综合贯通线实际参数建立了仿真模型,研究配电所集中设置柴油发电机作为高速铁路沿线与行车密切相关的通信、信号等重要负荷的备用电源可行性,分析线路在不同工况和不同补偿策略下的电压分布。仿真分析的结果确定了发电机进相运行的参数范围及提高发电机调节能力的条件。

In allusion to the existing problem of the disaster prevention design in grand train stations, the setting scheme of the emergency power supply to improve the supply reliability of railway power lines is selected by this paper And a simulation model is established which based on the actual parameter of a 78.3 km long full cable integrated through line in Wuhan-Guangzhou passenger dedicated line. The paper research on the feasibility that diesel generator was set in the distribution station and worked as a standby power supply of the important load, such as communication and signal along the high speed railway which is closely associated with the driving train. Voltage distribution in different conditions and different compensation strategies is also analyzed. The simulation result determine the parameter range of the generator leading running and the condition to improve the generator regulate ability
