【摘要】：摘要：在單相工頻交流供電的鐵路牽引供電系統(tǒng)中,由于分相區(qū)的存在,在一定程度上制約了電氣化鐵路向更高速、更重載的方向發(fā)展。本文圍繞列車(chē)過(guò)分相時(shí)實(shí)現(xiàn)不斷電、無(wú)沖擊兩大目標(biāo),基于電流信息進(jìn)行列車(chē)不斷電過(guò)分相系統(tǒng)的研究,研究的問(wèn)題主要包括系統(tǒng)方案、列車(chē)位置檢測(cè)方案、列車(chē)過(guò)分相電氣暫態(tài)過(guò)程、電子開(kāi)關(guān)工程設(shè)計(jì)等幾個(gè)方面。 本論文對(duì)現(xiàn)有的列車(chē)自動(dòng)過(guò)分相技術(shù)方案進(jìn)行了對(duì)比,重點(diǎn)研究了地面自動(dòng)過(guò)分相的現(xiàn)有系統(tǒng)方案和列車(chē)位置傳感器,并分析了它們的優(yōu)點(diǎn)與不足。在此基礎(chǔ)上對(duì)電子開(kāi)關(guān)列車(chē)不斷電過(guò)分相進(jìn)行系統(tǒng)優(yōu)化,提出了列車(chē)不斷電過(guò)分相系統(tǒng)的兩種新方案,分別是中性區(qū)無(wú)位置傳感器的系統(tǒng)方案和中性區(qū)安裝一套位置傳感器的系統(tǒng)方案。基于接觸網(wǎng)電壓和列車(chē)電流信息,進(jìn)一步研究了地面電子開(kāi)關(guān)的控制時(shí)序。本論文提出的方案,可有效縮短列車(chē)過(guò)分相的斷電時(shí)間,列車(chē)過(guò)分相時(shí)可保持牽引力不丟失。 本論文針對(duì)現(xiàn)有列車(chē)位置檢測(cè)方法應(yīng)用于電子開(kāi)關(guān)系統(tǒng)中存在的不足,提出了基于接觸網(wǎng)電流信息的列車(chē)位置檢測(cè)方法。通過(guò)研究牽引供電方式、接觸網(wǎng)結(jié)構(gòu)分析了該方法的可行性。對(duì)接觸網(wǎng)阻抗單元進(jìn)行建模,得出了承力索電流和吊弦電流的分布規(guī)律。提出了一種基于承力索電流信息的列車(chē)位置檢測(cè)方法和三種基于吊弦電流信息的列車(chē)位置檢測(cè)方法。以上列車(chē)位置檢測(cè)是通過(guò)監(jiān)測(cè)接觸網(wǎng)電流來(lái)實(shí)現(xiàn)的,因此本文設(shè)計(jì)了電流監(jiān)測(cè)裝置,并設(shè)計(jì)了將電流監(jiān)測(cè)裝置安裝在支柱和腕臂上的安裝方式。本文提出的列車(chē)位置檢測(cè)方法可準(zhǔn)確的定位列車(chē)受電弓的位置。 本論文從理論上對(duì)列車(chē)過(guò)分相的電氣暫態(tài)過(guò)程進(jìn)行了研究,探討了過(guò)電壓和過(guò)電流產(chǎn)生的機(jī)理。通過(guò)對(duì)暫態(tài)過(guò)程的分析提出了地面開(kāi)關(guān)切換過(guò)程中抑制過(guò)電流的解決方案,實(shí)現(xiàn)列車(chē)無(wú)沖擊通過(guò)分相區(qū)。在電子開(kāi)關(guān)控制過(guò)程中,接觸網(wǎng)電壓和開(kāi)關(guān)負(fù)載電流的相位信息非常重要,本文對(duì)常見(jiàn)的幾種相位檢測(cè)方法進(jìn)行了研究和對(duì)比,加權(quán)最小二乘法響應(yīng)快,魯棒性好,在諧波含量較大的電壓波形中能準(zhǔn)確的檢測(cè)出基波相位,將該相位檢測(cè)方法用于電子開(kāi)關(guān)的列車(chē)帶電過(guò)分相系統(tǒng)中檢測(cè)電壓、電流相位可以得到最優(yōu)的結(jié)果。 本論文進(jìn)行了電子開(kāi)關(guān)的器件選型和串聯(lián)器件均壓電路設(shè)計(jì)。并對(duì)晶閘管串聯(lián)閥組的門(mén)極觸發(fā)進(jìn)行的研究,基于光隔離驅(qū)動(dòng)技術(shù)研究了高壓自取能技術(shù),設(shè)計(jì)了從高壓側(cè)直接獲取電能提供給晶閘管門(mén)極觸發(fā)電路的取能電路,實(shí)驗(yàn)結(jié)果表明該取能電路可以滿足高壓晶閘管串聯(lián)閥組的觸發(fā)電路的電源需求。
[Abstract]:Abstract: in the single-phase AC power supply of railway traction power supply system, due to the existence of phase, constrained to a certain degree of electrified railway to more speed, more heavy direction. This paper focuses on the train when not excessive power, without the impact of the two major goals of research based on the current information of power train phase separation system, studies the problems mainly including system scheme, train position detection scheme, the train passing electrical transient process, electronic switch several engineering design.
In this paper, the existing automatic train phase scheme were compared, focusing on the ground automatic convert the existing system and train position sensor, and analyzes their advantages and disadvantages. On the basis of the electronic switch train phase uninterruptible power system optimization, puts forward two new schemes for power train phase separation system, respectively is the system scheme of sensorless neutral zone and the neutral zone to install a position sensor. The catenary voltage and current train based on further research on ground control timing electric switch. The proposed scheme can effectively shorten the outage time of train passing train. Excessive phase can be maintained when the traction is not lost.
This thesis focuses on the application of the existing train position detection method for electronic switch in the system, put forward the train position detection method based on current information catenary. Through the research of traction power supply system, the catenary structure is analyzed. The feasibility of the method for modeling contact impedance elements, obtained distribution of bearing cable and current hanger current. Based on the train position detection method of catenary current information and three kinds of train position detection method based on current information. Hanging above the train position detection is achieved by monitoring the catenary current, this thesis designed a current monitoring device, and designed the installation methods of current monitoring device is mounted on the pillar and wrist arm. The position of the pantograph positioning train position detection method in this paper can be accurate.
This paper from the theory of electrical transient process of phase separation was studied on the train, discussed the mechanism of overvoltage and overcurrent generated. Through the analysis of the transient process is proposed to suppress the solution to current switching process of ground switch, train no impact by phase. In the electronic switch control process. Catenary voltage and load current of the switch phase information is very important, this paper has conducted the research and comparison of several common phase detection method, the weighted least squares method of fast response, good robustness, can detect accurately the fundamental phase voltage waveform in large harmonic content, the phase detection method for detecting the voltage charged electronic train switch over phase system, the phase current can get optimal results.
This paper device selection electronic switch and serial devices are pressure circuit design. And the thyristor series valve gate trigger for research, optical isolation driving technology of high-pressure self energy technology based on the design from the high voltage side direct access to electrical energy that is supplied to the thyristor gate trigger can take the experimental results show that the circuit, the power circuit of high voltage thyristor series valve trigger circuit of power supply and demand.
