世界高速电气化铁道电能质量现状及治理措施

介绍了国际高速电气化铁道电能质量的现状、有关标准和改善电能质量方面的进展.探讨了我国为提高电能质量在接入系统电压等级、短路容量、供电方式、变压器类型、机车类型、接触网设计等方面应该采取的措施,在已运营电气化铁道上如何通过在机车侧、牵引变电所和公共连接点加设补偿滤波装置以及合理安排行车调度等方式来改善电能质量,并应考虑同相供电和高压直流供电等新型的供电方式.

The Present Status and Control Measures of Power Quality of World High-Speed Electric Railway

Talks about the present situation of international High-speed electric railway electric quality,points out the standards of electric quality,and analyzes how to improve the electric quality in these country.For the purpose of improve china's electric quality,this paper also take research on how to change the voltage grade,short-circuit capacity, power supply mode,transformer type,electric locomotive type and design of catenary for a new electric railway,and how to arrange train operation,set proper compensation equipment in locomotive,traction substation and points of common connection for a runing electric railway.At the same time,new type of power supply system such as without phase exchange and high direct voltage supply system should be considered in the development of China high-speed electric railway
