【摘要】：目前我国高速列车生产企业主要通过从国外引进先进技术,进而消化吸收,最终全面实现具有我国自主知识产权的高速列车国产化。但是高速列车牵引传动系统的设计理论依据不是很清楚,急需加强这方面的深入研究。本文在此背景下展开了对动车组牵引传动系统设计方法的研究工作。本文对牵引传动系统参数设计方法进行了详细研究。在分析动车组牵引传动系统的研究现状的基础上,总结了各类型动车组牵引传动系统的特点,匹配计算了牵引传动系统各单元功率,分析了牵引传动系统参数设计方法,给出理论依据。主要包括：分析计算了牵引逆变器和脉冲整流器的额定电压和电流；从满足整流器交流侧有功功率稳态指标以及等效干扰电流规定值两方面考虑,对牵引变压器漏电感取值进行了理论分析；在牵引变流器的中间直流环节参数设计中,主要对中间支撑电容以及二次谐振回路电感电容的取值进行了理论分析设计。采用已知动车组参数验证了理论设计方法的正确性。为仿真验算动车组牵引传动系统的设计参数,论文分析了牵引传动系统中脉冲整流器及牵引逆变器的控制策略,其中脉冲整流器采用瞬态直接电流控制策略,并结合多重化移相技术以提高系统容量、减少网侧谐波电流：牵引逆变器采用磁场定向矢量控制策略,并采用多个调制策略以保证动车在各个工况下正常运行。仿真验算设计方法以及设计参数的合理性。此外,本文理论分析了IGBT功率模块的热损耗,利用英飞凌IGBT仿真软件对不同电压等级的IGBT整流逆变电路热损耗进行了仿真分析。最后,本文使用Matlab simulink搭建了动车牵引传动系统的仿真模型,对动车组参数进行仿真验算。为了使仿真验算更友好、更直观、更方便,本文结合了Matlab GUI (Graphical User Interface)图形用户界面,设计了牵引传动系统仿真人机交互界面。
[Abstract]:At present, China's high-speed train production enterprises mainly through the introduction of advanced technology from abroad, and then digest and absorb, Finally, the localization of high-speed trains with independent intellectual property rights of our country is fully realized. However, the theoretical basis for the design of traction transmission system of high-speed trains is not very clear. In this paper, the design method of traction transmission system of EMU is carried out. The parameter design method of traction transmission system is studied in detail in this paper. On the basis of the research status of traction transmission system, The characteristics of traction transmission system of various types of EMU are summarized, the power of each unit of traction transmission system is matched and calculated, and the parameter design method of traction transmission system is analyzed. The main contents are as follows: the rated voltage and current of the traction inverter and the pulse rectifier are analyzed and calculated, the steady state index of the active power on the AC side of the rectifier and the fixed value of the equivalent interference current are considered. The leakage inductance of traction transformer is analyzed theoretically. The theoretical analysis and design of the intermediate supporting capacitance and the inductance capacitance of the secondary resonant circuit are carried out. The correctness of the theoretical design method is verified by using the known EMU parameters, and the design parameters of the EMU traction transmission system are simulated and calculated. In this paper, the control strategies of pulse rectifier and traction inverter in traction drive system are analyzed. The pulse rectifier adopts transient direct current control strategy, and combines the technology of multiple phase shift to improve the system capacity. To reduce the harmonic current on the grid side: the traction inverter adopts the flux-oriented vector control strategy, and adopts several modulation strategies to ensure the normal operation of the motor car under various working conditions. The design method of simulation and checking calculation and the rationality of the design parameters are also presented. In this paper, the thermal loss of IGBT power module is analyzed theoretically, and the thermal loss of IGBT rectifier inverter circuit with different voltage levels is simulated by Infineon IGBT simulation software. In this paper, Matlab simulink is used to build the simulation model of traction transmission system of motor vehicle, and the emulation calculation of the parameters of emus is carried out. In order to make the simulation and calculation more friendly, more intuitive and more convenient, this paper combines the graphical user interface of Matlab GUI graphical User interface. The man-machine interface of traction transmission system simulation is designed.
