In order to create a set of experimental instrument on the high-speed railway traction power supply system for the high school students and railway engineers, after having carefully studied this system, the models of catenary, high-speed trains, integrated grounding systems, and remote monitoring system are firstly given in detail. Besides, a set amount of the speed railway traction power supply integrated dynamic simulation experiment system with the scaled-down electrical and physical quantity is designed and developed carefully. The behaviors of the high-speed railway traction power supply in each module can be simulated by this experimental system accurately. The reaction and the electrical quantity can truly reflect the high-speed railway traction power supply system operating conditions. This system helps to improve the relevant practitioners and tertiary students’ recognition for high-speed railway traction power supply system, and provides the experimental environment for research institutes.
