基于TCMS的列车辅助变流器启动及复位方法研究

摘要

In order to solve the problem that the start-up failure and the normal equipment are isolated by the TCMS due to the misoperation of the auxiliary converter during the start-up control of the medium voltage power supply, this article designed a pre-set clear and late backup troubleshooting method. The control strategy can not only effectively avoid unnecessary medium voltage load shedding, but also significantly improve the reliability of the train medium voltage power supply system and passenger comfort, it also ensures the smoothness of the auxiliary converter starting logic cycle. Ground simulation platform simulation and vehicle field test verification results were very effective.%为了解决在中压电源并网启动控制过程中,因辅助变流器启动逻辑误判而出现的启动失效和正常设备被列车控制管理系统隔离的问题,设计一种先期前置清零和后期备份的故障排除方法,该控制策略可有效地避免不必要的中压减载,显著提高列车中压供电系统的可靠性及旅客乘车的舒适度,保证辅助变流器启动逻辑循环的流畅性.该方法经地面联调平台仿真验证和车辆现场试验验证,效果良好.
