【摘要】 介绍了电气化铁路牵引站V/v型牵引变压器接入系统的谐波评估模型以及利用该模型进行谐波评估的计算方法。对电气化铁路牵引站接入110 kV电网的2种典型供电方案进行了实例分析,介绍了在具体工程中如何考虑牵引站的谐波、背景谐波各牵引站之间的谐波影响,从系统的谐波电压分布和注入系统谐波电流两方面进行评价。更多还原

【Abstract】 The harmonic assessment model of electrified railway’s V/v traction transformer accessed power system and the alculation method using this model to carry on harmonic assessment are introduced in this paper.Example analysis on the two kinds of power supply plans for railway traction substation access the 110 kV network is taken,including how to consider the harmonic influence between the traction substation’s harmonic,power system’s background harmonic and each traction substation’s harmonic in specific subject,and evaluation from two aspects of the harmonic volt distribute in system and harmonic current poured into system.更多还原
