摘要
分析了动车组空调装置的主要用电设备,并对辅助供电系统的结构原理进行了介绍。运用软件MATLAB/SIMULINK成功地建立了主电路模型。仿真表明,动车组空调装置顺序启动与同时启动相比,动车组供电母线的冲击电流与电压降分别减小73.51%和95.24%,仿真结果验证了空调装置顺序启动的必要性。
The paper analyzed the main electric equipment of HVAC （Heating, Ventilation and Air Conditioning） apparatus and introduced structural principle of the auxiliary power system for EMUs. The power circuit model of the auxiliary power system was setup successfully by using MATLAB/SIMULINK software. The simulation results had proven that the surge current and voltage in power bus had been respectively reduced 73.51% and 95.24% when the HVAC apparatus start in sequence. The simulation results also validate the necessity of the start in sequence for HVAC apparatus.
