Study on the Control Method of High-Speed Train Traction Motor Continuous Load

Load torque of the high-speed train traction motor is discussed in this paper, including constituent elements of the load torque (Hyung-Min Ryu

et al

. 2002) and how to simulate the torques. This paper establish the mathematical model of the traction motor from the energy point of view, the equivalent damping torque and the equivalent inertia loads has been obtained under continuous load conditions(Akpolat

et al

. 1999). In order to emulate the actual operation, algorithms were tested and verified with the use of Matlab/Simulink first, and then a emulation platform was built under laboratory conditions, the platform is consisted by two induction machines and a small flywheel. Experiments of emulating a high-speed train traveling on certain given line is executed with the use of the DASPACE system.
