The Electric Motor Train Units (EMU) load is the main load of the power traction system for high-speed railway, so the accuracy of load characteristic description has an important influence on establishing traction load model. This article designed the logical control strategy for traction drive system and set up a complete digital simulation model of the traction drive system for CRH2 EMU, and then analyzed the traction and braking characteristics under different operating conditions, for example, ideal operation, voltage fluctuation of power supply system and different road conditions such as slopes, curves and tunnels. Simulation results show that the designed model is effective and accurate.
