摘要研究目的：随着铁路运量的增长，实际运行中会出现牵引网电压低于电力机车最低允许电压的情况。因此，改善牵引网电压，在电气化铁路的设计中是一项重要课题。目前改善供电臂电压水平的措施有：提高牵引变电所牵引侧母线电压、采用串联电容补偿装置、采用并联补偿装置、采用载流承力索或加强线等。

研究结论：本文分析了改善牵引网电压的几种方法及其工作原理，针对宝成线这种山区铁路的运量大、铁路沿线电力系统电源薄弱的特点，通过对宝成线马角坝牵引变电所的牵引供电方案的研究和供电理论计算，最终得出在马角坝牵引变电所的馈线侧同时安装串联补偿装置和动态无功补偿装置，提高了马角坝牵引变电所供电臂的电压水平，从而使牵引网末端其电压达到20 kV。

Abstract：Research purposes: With the increment of railway traffic volume，sometimes it occur that the actual operation voltage of the feeding system is lower than the minimum allowed voltage of electric locomotive．Therefore，to improve the traction voltage of traction substation is an important work in design of electrified railway．At present，the ways of improving the voltage level of feeding section include：to improve the bus voltage of the traction side of substation，to use series capacitance compensation device，to US parallel compensation device and to use carrying eatenary or or strengthening wire．

Research conclusions:In this paper，the ways of improving voltage of feeding system and their working principles are analyzed．According to the characteristics of large traffic volume of Baoji—Chengdu Railway and poor power supply of feeding system Mong the railway，based on the study on the scheme of traction power supply of Majiaoba Traction Substation and the calculation of power supply in theory，it is decided to install the series compensation device and dynamic reactice——load compensation device Oil feeding wire side to improve the voltage level of the feeding section of Majiasoba Traction substation for making the voltage up to 20 kV on the end of traction power supply network．
