Problems solved by technology

The existing domestic high-speed train traction drive control system hardware-in-the-loop simulation platform performs real-time simulation for the normal operation behavior of the system. It can only simulate abnormal working conditions in some components offline and manually, and test the traction drive control unit TCU The main purpose is the function of the traction drive control system, and it does not involve the system / subsystem level fault injection and simulation of the traction drive control system, that is, it is impossible to simulate the fault operation behavior of the traction drive control system in real time
