摘要
介绍一起少见的220 kV母线相继故障,通过对母线保护、线路保护动作行为和故障录波波形进行分析,采用一次系统故障演变与继电保护动作时序相结合的分析方法,阐述了故障形成和发展的机理,并对母线保护、线路对侧纵联保护和故障录波动作行为进行评价。
Combining with the resolution of behaviors of the busbar and line protections,an unusual successively fault accident on a 220 kV busbar is analyzed in this paper.Base on the research of evolvement of the primary fault,and the operations sequence of the protections,the mechanism involved in this successively fault is brought out.In addition,behaviors of the protection,line pilot protections and form recorders are appraised also.
