目前,电气化铁路在交通运输中的重要性不言而喻,而作为电气化铁道最主要的组成部分,牵引供电系统无疑也具有举足轻重的地位。它是牵引负荷的动力来源,因此其供电质量的优劣,对电气化铁路运输而言有着重大影响。当前的牵引供电系统有着许多问题,它们降低了供电的效率和质量,威胁着电气化铁道运行的可靠性和安全性。因此,分析并解决这些问题是很有必要并且很有意义的。本文将列举当前供电系统中存在的谐波、无功、负序等问题,并提出相应的解决对策。
At present, the importance of electrified railway in transportation is self-evident. As the most important component of electrified railway, traction power supply system undoubtedly also plays a decisive role. It is the source of traction load, so the quality of its power supply has a significant impact on the electrified railway transport. The current traction power supply system has many problems that reduce the efficiency and quality of power supply and threaten the reliability and safety of the electrified railway operation. Therefore, it is necessary and meaningful to analyze and solve these problems. This article will list the current power supply system exists in the harmonic, reactive, negative sequence and other issues, and put forward the corresponding solutions.
