摘要
根据温州市域动车组牵引系统的特点,提出了一种电动车组牵引系统接地故障诊断与保护的控制方法。试验结果表明,该方法能准确诊断牵引系统发生接地的区域,根据接地区域的不同,执行不同的保护策略,可在保证牵引系统安全的同时,提升列车的可用性。
According to the characteristics of the traction system of Wenzhou city EMUs,a control method for the inspection and protection of ground fault in the traction system of electric EMUs was proposed.The test results show that the method could accurately inspect the grounding area of the traction system,and implement different protection strategies according to the grounding area,which could improve the availability of the train while ensuring the safety of the traction system.
