Electro-mechanical re-adhesion control simulator for inverter-driven railway electric vehicle

In this paper, an electromechanical re-adhesion control simulator is proposed for an inverter-driven railway electric vehicle. The basic characteristics of the re-adhesion phenomenon in electric railway systems is analyzed, and an electromechanical model of the railway system is developed based upon those characteristics. Based on the system model analysis, a electromechanical re-adhesion control simulator is designed. The proposed simulator has a wheel-to-wheel structure, which corresponds to the rail-to-wheel of real railway systems. To evaluate the feasibility of the simulator, experiments of re-adhesion are performed with a simple re-adhesion control algorithm. Experimental results prove that the simulator provides an electrical and mechanical environment similar to real railway electric vehicle systems.
