Research on Dynamic Simulation of Mine Electric Locomotive

以矿用电机车双闭环PWM斩波调速系统为研究对象,根据动力学理论,建立了转速PI控制器、电流PI控制器和PWM斩波调速器的数值仿真模型,根据矿用电机车的运行条件,分析了空载启动、重载启动和重载制动3种工况下矿用电机车的动态响应特性。仿真结果为矿用电机车双闭环PWM斩波调速系统设计及控制提供了理论参考。

The PWM chopper speed regulating system of mine electric locomotive is taken as the research object in this paper, ccording to the theory of dynamics, The numerical simulation model of the speed PI controller, currentPI controller and PWM chopper speed regulator was put forward, the operation process of mine electric locomotive was simulated by simulink, The dynamic response characteristics of no-load starting, heavy load starting and heavy braking under three working conditions of mine electric locomotive were analyzed. The simulation results provide a theoretical reference for t The PWM chopper speed regulating system of mine electric locomotive.
