随着电气化铁路的迅速发展,电铁牵引负荷产生的高次谐波,除了对牵引供电系统造成危害外,还会造成电力系统谐波污染,因而,电铁的谐波危害已成为制约我国电气化铁道发展的重要因素。介绍电力系统的谐波定义以及国家对谐波的限制标准,结合朔黄铁路牵引供电系统的概况分析了电铁谐波对铁路运输的影响,提出了抑制电铁谐波的方法和措施。
With the rapid development of electrified railway, the higher harmonics generated by the traction load of the electrified railway will cause the harmonic pollution of the power system in addition to the damage to the traction power supply system. Therefore, the harmonic harm of the electrified railway has become a problem that restricts the electrification Railway development of an important factor. This paper introduces the definition of harmonic in power system and the national standard of harmonic restriction. Combined with the general situation of traction power supply system in Shuohuang Railway, the influence of electrified railway harmonics on railway transportation is analyzed. The methods and measures of suppressing harmonic of electric railway are put forward.
