摘要
随着我国高速铁路的不断发展,数字化牵引变电所的研究开始引人关注。数字化牵引变电所是现代智能牵引变电所的发展方向,具有自愈、可靠、高效等特征,自愈功能作为保证牵引网可靠、安全运行的关键功能,是数字化变电所的研究重点。本文在系统阐释数字化牵引供电系统自愈重构目的及原则的基础上,通过对典型全并联AT供电方式自愈方案的梳理,提出针对越区供电方式的自愈方案,并详细论述了母线越区及非母线越区情况下的自愈方案及其流程。
With the continuous development of China's high speed railways,the research of digitalized traction substation has begun to attract the people's attention.Digitalized traction substation is the development direction of modern intelligent traction substation,which has the characteristics of self-healing,reliability and high efficiency.As the key function to ensure the reliable and safe operation of traction network,self-healing function is the research focus of digitalized substation.Based on the systematic explanation of the purpose and principle of the self-healing reconstruction of digitalized traction power supply system,this paper puts forward a self-healing scheme for over-zone power supply mode by combing the self-healing schemes of typical full parallel at power supply mode,and discusses in detail the self-healing scheme and its process in case of bus over-zone and non-bus over-zone.
