HIL Real-Time Simulation of Electric Locomotive AC Drive System

Taking the AC drive system of six-axle electric locomotive as an example, the mathematical model for AC drive system of electric locomotive is established by setting up the models of net side converter,DC link,inverter and induction motor.By means of the MATLAB/Simulink simulation system,using the method of HIL(hardware-in-loop) with real controller and virtual plants,the HIL realtime simulation of AC drive system of electric locomotive is realized.The simulation results under many working circumstances show the good consistency between the HIL results and field experiment results.By combining the present HIL simulation platform with the simulation system of rapid control prototype,the standard system design platform is proposed.The method can effectively validate system design.
