摘　　要：铁路电气化具有运输能力大,综合能源利用率高,节能减排等明显优点,随着科学技术和国民经济的快速发展,我国铁路电气化进入了一个非常快的发展时期。但是,电气化铁路牵引负荷由于其单相运行、整流供电、负荷变化等原因,对所接入的电力系统带来功率因数低、三相电压不平衡、谐波超标、电压波动等严重的电能质量问题。河南地处全国铁路网中心,铁路电气化比例位于全国前列。本文结合河南电网的情况及电气化铁路发展的特点,讨论了河南电气化铁路负荷对电网电能质量的影响,并给出了相应的解决措施。As science and technology and the rapid development of the national economy, China＇s railway electrification which with large transport capacity, high comprehensive energy efficiency, energy saving and emission reduction and other obvious advantages, got into a very fast development period.However, the electrified railway traction load because of its single-phase operation, rectifier power supply, load ch^nges and other factors causes serious power quality problems to its access power system, such as low power factor,three-phase voltage unbalance,harmonic excess,voltage fluctuation and so on.Henan province is situated at the center of the national railway network, which railway electrification ratio is located at the fore^ont in china.This paper combing with the situation in henan power grid and the characteristics of electric railway development, discussed the impact of electrified railway load of henan province on power quality, and given the corresponding solution measure.
