【摘要】：隨著鐵路的不斷發(fā)展,電氣化鐵路與電力系統(tǒng)的聯(lián)系也越來越緊密。鐵路沿線分布著通信系統(tǒng)、信號系統(tǒng)等不同類型的非牽引負荷,其電力供電方案直接關系到行車安全、運營費用和建設投資。由于電力負荷的用電問題缺乏深入的研究和足夠的重視,這樣就使電力負荷用電困難或得不到經濟合理的解決。電氣化鐵路的快速發(fā)展,為合理利用牽引供電系統(tǒng)為沿線負荷提供電源提供了技術平臺。面對技術全球化的趨勢,我國要積極借鑒、吸納國外先進技術,加大我國高鐵的優(yōu)勢,推動中國高鐵又快又好地"走出去",在服務"一帶一路"戰(zhàn)略中發(fā)揮更大的作用。因此借鑒國外電氣化鐵路成功的經驗,提出多種適用于鐵路的由牽引供電系統(tǒng)取電的電力供電方案,來優(yōu)化和完善鐵路的電力供電系統(tǒng),不論是對鐵路系統(tǒng)還是電力系統(tǒng)都有著重大深遠的現(xiàn)實意義,需要進行系統(tǒng)的研究。本文對電氣化鐵路電力系統(tǒng)現(xiàn)狀進行了調研,總結出多種利用牽引供電系統(tǒng)為鐵路沿線電力負荷供電的電力供電方案:接觸網取電分布式供電方案、牽引變電所取電分布式供電方案、交直交電源設備集中式供電方案、變電所與牽引變電所合建方案;對以上電力供電方案的工作原理和特點進行初步分析,并確定需要進一步研究的問題;根據某高速鐵路數據,運用Matlab/Simulink仿真軟件,建立了牽引供電系統(tǒng)、動車組、交直交電源設備、電力貫通線、電力負荷的模型,組成了各方案的仿真模型,分析結果得出供電質量;從供電質量、對牽引供電系統(tǒng)的影響、可靠性和運行維護工作、投資成本方面進行綜合對比,得出各方案的特點及適用場合。
[Abstract]:With the development of railway, the relationship between electrified railway and power system is more and more close. There are different types of non-traction load such as communication system and signal system along the railway. Its power supply scheme is directly related to driving safety, operating expenses and construction investment. Due to the lack of in-depth research and sufficient attention to the power load problem. In this way, the power load is difficult to use or can not be solved economically and reasonably. The rapid development of electrified railway. It provides a technical platform for the rational use of traction power supply system to provide power supply for load along the line. Facing the trend of technology globalization, our country should actively draw lessons from foreign advanced technologies and increase the advantages of high-speed rail in our country. Promoting China's high-speed railway to "go out" quickly and well, and play a greater role in serving the "Belt and Road" strategy. Therefore, draw lessons from the successful experience of foreign electrified railways. To optimize and perfect the power supply system of railway, it is of great practical significance to optimize and perfect the power supply system of railway, both for railway system and power system. This paper investigates the current situation of electrified railway power system. This paper summarizes a variety of power supply schemes which use traction power supply system to supply electric load along railway line: catenary power distributed power supply scheme, traction substation power distributed power supply scheme. AC-DC power supply equipment centralized power supply scheme, substation and traction substation construction plan; The working principle and characteristics of the above power supply scheme are analyzed preliminarily, and the problems that need further research are determined. According to the data of a high speed railway, the models of traction power supply system, EMU, AC DC power supply equipment, power transmission line and electric load are established by using Matlab/Simulink simulation software. The simulation model of each scheme is made up, and the power supply quality is obtained by analyzing the results. From the aspects of power supply quality, influence on traction power supply system, reliability, operation and maintenance work and investment cost, the characteristics and applicable situation of each scheme are obtained.
