摘要
以六轴电力机车的电传动系统为例,通过对电网侧变流器、直流环节、逆变器和异步电机的建模,构建电力机车交流传动系统的数学模型。借助于MATLAB/Simulink仿真系统,采用"实际控制器+虚拟被控对象"的硬件在线半实物仿真HIL形式,实现了电力机车交流传动系统的半实物闭环实时仿真。各种工况下的仿真实验表明,半实物仿真结果与地面实验结果有很好的一致性。通过现有的半实物仿真和快速控制原型仿真的组合,形成标准化的系统设计平台,可以有效预验证系统设计。
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 real-time 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.
