【摘要】 首先介绍了电气化铁路的用电特性,然后给出了电气化铁路的谐波特点。根据电气化铁路的供电特性给出了电铁产生谐波污染的原因,随后提出了一些治理谐波污染的措施和方法,最后为从根本上治理谐波污染提出了一种新的方案PWM整流-斩波取代现在所用的晶闸管相控整流桥。更多还原

【Abstract】 Electrification railway′s characteristics are firstly introduced.Secondly the harmonic characteristics of electrification railway are presented.According to electrification railway′s characteristics the features and effects on power system of harmonic are analyzed.The measures to reduce the harmonic emission are provided.In the end,A new project is put forward in order to restrain harmonic radically PWM rectifier-chopper instead of SCR bridge which is used now.更多还原
