China Northern Railway (CNR) Group, has recently begun to develop Traction Control Units (TCUs) for AC electric locomotives. Since everything is started from scratch, almost all functions including various diagnosis functions must be thoroughly evaluated and tested; there is no time to set up a full-scale power test bench. Under these circumstances, CNR decided to use the hardware-in-loop (HIL) approach, well established in the automotive industry, to test their TCU software and hardware.
