“中华之星”交流传动电动车组特性控制模式改进及仿真

Modification of characteristic control mode of China Star AC drive EMU and its simulation

针对“中华之星”高速电动车组试验期间恒速特性控制暴露出的不足,借鉴以往交直传动机车准恒速特性控制的成熟经验,提出一种改进的特性控制模式,并采用该模式对列车在京沈客运通道的运行进行仿真分析。结果表明,其具有很好的自适应性和稳定性,建议对现有恒速特性控制模式进行改进优化。

With respect to its constant-speed characteristic control's defects exposed during China Star EMU's trial running,this article puts forward a modified control model based on DC drive locomotive's matured quasi-constant-speed characteristic control. Simulation and analysis are made for operation in passenger-dedicated line between Beijing and Shenyang based on this modified model. Results show that it boasts of good adaptability and stability. So it is suggested that current control mode should be optimized and modified.
