【摘要】：目前我國高速列車生產(chǎn)企業(yè)主要通過從國外引進先進技術(shù),進而消化吸收,最終全面實現(xiàn)具有我國自主知識產(chǎn)權(quán)的高速列車國產(chǎn)化。但是高速列車牽引傳動系統(tǒng)的設(shè)計理論依據(jù)不是很清楚,急需加強這方面的深入研究。本文在此背景下展開了對動車組牽引傳動系統(tǒng)設(shè)計方法的研究工作。本文對牽引傳動系統(tǒng)參數(shù)設(shè)計方法進行了詳細(xì)研究。在分析動車組牽引傳動系統(tǒng)的研究現(xiàn)狀的基礎(chǔ)上,總結(jié)了各類型動車組牽引傳動系統(tǒng)的特點,匹配計算了牽引傳動系統(tǒng)各單元功率,分析了牽引傳動系統(tǒng)參數(shù)設(shè)計方法,給出理論依據(jù)。主要包括：分析計算了牽引逆變器和脈沖整流器的額定電壓和電流；從滿足整流器交流側(cè)有功功率穩(wěn)態(tài)指標(biāo)以及等效干擾電流規(guī)定值兩方面考慮,對牽引變壓器漏電感取值進行了理論分析；在牽引變流器的中間直流環(huán)節(jié)參數(shù)設(shè)計中,主要對中間支撐電容以及二次諧振回路電感電容的取值進行了理論分析設(shè)計。采用已知動車組參數(shù)驗證了理論設(shè)計方法的正確性。為仿真驗算動車組牽引傳動系統(tǒng)的設(shè)計參數(shù),論文分析了牽引傳動系統(tǒng)中脈沖整流器及牽引逆變器的控制策略,其中脈沖整流器采用瞬態(tài)直接電流控制策略,并結(jié)合多重化移相技術(shù)以提高系統(tǒng)容量、減少網(wǎng)側(cè)諧波電流：牽引逆變器采用磁場定向矢量控制策略,并采用多個調(diào)制策略以保證動車在各個工況下正常運行。仿真驗算設(shè)計方法以及設(shè)計參數(shù)的合理性。此外,本文理論分析了IGBT功率模塊的熱損耗,利用英飛凌IGBT仿真軟件對不同電壓等級的IGBT整流逆變電路熱損耗進行了仿真分析。最后,本文使用Matlab simulink搭建了動車牽引傳動系統(tǒng)的仿真模型,對動車組參數(shù)進行仿真驗算。為了使仿真驗算更友好、更直觀、更方便,本文結(jié)合了Matlab GUI (Graphical User Interface)圖形用戶界面,設(shè)計了牽引傳動系統(tǒng)仿真人機交互界面。
[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.
