Solution for Speed Sensorless Control System Restarting at Unknown Speed of Traction Motor
摘要
Abstract
In order to solve the problem that a traction motor may restart at unknown speed when a speed sensorless control system is applied in electric traction drives, a new strategy using regenerative mode to replace coasting mode is presented on the basis of analyzing the trains operating state and the root causes of this problem, and the effectiveness of this method is verified by numerical simulation using Matlab/Simulink. Taking the parameters of the electric multiple unit (EMU) CRH3 and the electric locomotive HXD3 for example, the influence of this strategy on speed and running time of the motor train is calculated. The results show that compared with those of passing the phase insulator under coasting mode, the loss in both of speed and running time is less than 2% for the EMU running at a speed more than 200 km/h, and less than 7% for heavy haul freight train running at more than 60 km/h.关键词
