摘要
在高速铁路接触网与地铁供电系统的长距离并行运行情况下,采用AC 2×25 kV电压供电的高速铁路接触网对DC 1 500 V电压供电的地铁供电系统会造成较大的电磁感应影响,对地铁安全运行存在严重的安全隐患。针对高速铁路接触网与地铁供电系统不同供电方式的特点,建立了高速铁路接触网对地铁直流供电系统的电磁干扰数学模型,并在MATLAB软件环境中进行了仿真计算;在此基础上,进行了动车组不同工况下的电磁干扰仿真分析,并提出了解决此问题的技术措施。
In the condition when the high-speed railway OCS operates parallel with the subway power supply system for a long distance,the former that adopts the voltage AC 2 × 25 kV will greatly influence the latter because of the electromagnetic interference （EMI）,which will cause seri ous security risks for subway operation.According to the characteristics of different power supply patterns,a mathematical model of EMI algorithm caused by high-speed railway OCS on subway power supply system is established,and this model is simulated in MATLAB software condition.Based on the algorithm,EMI simulation analysis is conducted in different conditions of motor train unit,some technical measures are provided to solve the interference problem.
