电铁谐波的产生及湖北省电铁谐波情况

Electric Locomotive Harmonic and Electric Railway Harmonic Instance in Hubei Province

电铁为单相整流负荷 ,它在消耗电能的同时向供电系统注入大量的高次谐波 ,对电能质量产生危害。文章从理论上论述了电气化机车谐波产生的原理 ,并结合多年来对湖北省电铁谐波监测情况 ,对其特点进行了归纳 ,最后对谐波治理进行探讨。

The electric locomotive is a single phase reclified load.During it consumes electric power,feeds back a great amount of high order harmonic to energy supply system and jeopardizes the electric power quality.The article discusses the principle of harmonic created by electric locomotive sumnarizes its characteristic through the measurment of electric railway harmonic in Hubei Province for many years and finally probes the harmonic control.
