【摘要】：近年來，環(huán)境問題引起了全社會(huì)的廣泛關(guān)注，人們對(duì)于環(huán)境保護(hù)的要求越來越高。電動(dòng)汽車因?yàn)槠涔?jié)能環(huán)保的獨(dú)特優(yōu)勢(shì)，擁有廣闊的開發(fā)應(yīng)用前景。電動(dòng)汽車中的電力電子器件相比傳統(tǒng)汽車大大增加，由此帶來了復(fù)雜的汽車電磁兼容問題。其中，電機(jī)驅(qū)動(dòng)系統(tǒng)是電動(dòng)汽車中最主要的電磁干擾源，其產(chǎn)生的電磁干擾使得汽車難以滿足相關(guān)電磁兼容標(biāo)準(zhǔn)，并對(duì)汽車自身的安全行駛和外部環(huán)境產(chǎn)生不良的影響。本文針對(duì)電動(dòng)汽車電機(jī)驅(qū)動(dòng)系統(tǒng)的傳導(dǎo)電磁干擾問題進(jìn)行了相關(guān)研究，主要工作如下： ①分析了電機(jī)驅(qū)動(dòng)系統(tǒng)電磁干擾的產(chǎn)生機(jī)理。根據(jù)傳導(dǎo)電磁干擾耦合路徑的不同，分別分析了電機(jī)驅(qū)動(dòng)系統(tǒng)傳導(dǎo)電磁干擾的共模和差模耦合路徑。 ②在傳導(dǎo)電磁干擾頻率范圍內(nèi)，研究了永磁同步電機(jī)的高頻等效模型。利用測(cè)試得到的電機(jī)端口阻抗特性，采用基于矢量匹配法的數(shù)學(xué)擬合方法得到了阻抗等效模型的RLC參數(shù)，據(jù)此建立了高精度的電機(jī)高頻電路模型。根據(jù)多導(dǎo)體傳輸線理論，提出了線纜傳輸線電路模型的建模方法。 ③在電磁屏蔽室搭建了純電動(dòng)電機(jī)驅(qū)動(dòng)系統(tǒng)傳導(dǎo)電磁干擾實(shí)驗(yàn)平臺(tái)，采用本文提出的建模方法建立了系統(tǒng)的共模和差模傳導(dǎo)電磁干擾仿真模型。在100kHz—30MHz的頻率范圍內(nèi)，仿真了驅(qū)動(dòng)系統(tǒng)在LISN（人工電源網(wǎng)絡(luò)）處的干擾電壓和電機(jī)側(cè)的干擾電流。通過仿真和實(shí)測(cè)結(jié)果的對(duì)比驗(yàn)證了本文電機(jī)驅(qū)動(dòng)系統(tǒng)傳導(dǎo)電磁干擾預(yù)測(cè)方法的正確性和可行性，同時(shí)也說明了系統(tǒng)各部件建模方法的正確性。 ④利用混合動(dòng)力汽車和混動(dòng)實(shí)驗(yàn)平臺(tái)進(jìn)行了實(shí)驗(yàn)研究。在混合動(dòng)力汽車三種不同狀態(tài)下（常規(guī)、高速、充電）測(cè)量了電機(jī)驅(qū)動(dòng)系統(tǒng)中的傳導(dǎo)電磁干擾電流頻譜。通過對(duì)實(shí)驗(yàn)數(shù)據(jù)的分析，確定了電機(jī)驅(qū)動(dòng)系統(tǒng)電磁干擾頻帶寬度以及干擾耦合路徑，同時(shí)驗(yàn)證了對(duì)電機(jī)驅(qū)動(dòng)系統(tǒng)電磁干擾的產(chǎn)生機(jī)理。建立了混動(dòng)電機(jī)驅(qū)動(dòng)系統(tǒng)的傳導(dǎo)電磁干擾仿真模型，通過模型仿真、混動(dòng)實(shí)驗(yàn)平臺(tái)實(shí)測(cè)和混合動(dòng)力實(shí)車的測(cè)試結(jié)果，進(jìn)一步驗(yàn)證了建模方法的可行性和正確性。 ⑤利用測(cè)功機(jī)實(shí)驗(yàn)平臺(tái)，，進(jìn)一步測(cè)試了電機(jī)驅(qū)動(dòng)系統(tǒng)在實(shí)際工作中多種條件下（空載、帶載、反向充電）的傳導(dǎo)干擾，獲得了三種工況下的實(shí)驗(yàn)數(shù)據(jù)。將實(shí)驗(yàn)數(shù)據(jù)與仿真模型的計(jì)算數(shù)據(jù)進(jìn)行對(duì)比的結(jié)果表明，本文的建模方法及仿真模型是正確有效的，可為解決汽車工程中的電磁兼容問題提供理論依據(jù)。
[Abstract]:In recent years, environmental problems have aroused widespread concern in the whole society, and people are increasingly demanding for environmental protection. Electric vehicles have broad prospects for development and application because of their unique advantages of energy-saving and environmental protection. Among them, the motor drive system is the most important source of electromagnetic interference in electric vehicles, the electromagnetic interference produced by the motor drive system makes it difficult to meet the relevant electromagnetic compatibility standards, and has a negative impact on the safety of the vehicle itself and the external environment. The main tasks are as follows:
The generation mechanism of EMI in motor drive system is analyzed. According to the different coupling paths of conducted EMI, the common mode and differential mode coupling paths of conducted EMI in motor drive system are analyzed respectively.
(2) In the frequency range of conducted EMI, the high frequency equivalent model of PMSM is studied. The RLC parameters of the equivalent impedance model are obtained by the mathematical fitting method based on vector matching method according to the impedance characteristics of PMSM ports measured. A high precision high frequency circuit model of PMSM is established according to the multi-conductor transmission line. A modeling method of cable transmission line circuit model is proposed.
(3) Conducted EMI experimental platform of pure electric motor drive system was built in electromagnetic shielding room, and the simulation models of common mode and differential mode conducted EMI were established by using the modeling method proposed in this paper. The correctness and feasibility of the prediction method of conducted EMI in motor drive system are verified by comparing the simulation results with the measured results, and the correctness of the modeling method for each part of the system is also illustrated.
(4) Experiments were carried out on hybrid electric vehicle and hybrid experimental platform. The spectrum of conducted EMI current in motor drive system was measured under three different states (conventional, high speed, charging) of hybrid electric vehicle. The simulation model of conducted EMI of hybrid motor drive system is established. The feasibility and correctness of the modeling method are further verified by the simulation, the test results of hybrid experimental platform and hybrid electric vehicle.
_Using the dynamometer experimental platform, the conductive interference of the motor drive system under various conditions (no-load, on-load, reverse charging) in practical work is further tested, and the experimental data under three working conditions are obtained. It can provide a theoretical basis for solving electromagnetic compatibility problems in automotive engineering.
