Train Ethernet Backbone(TEB) 구성에 따른 신뢰도 분석

초록

As the usage of the electric power train increases, the importance of the control network between the electric control devices grows. IEC proposed a revision of IEC-61375, a standard of the networking among electric devices within a train, to adopt Ethernet as a backbone of train network. This paper performed the reliability analysis of three configurations of Ethernet-based networking within a electric power train that are recommended in IEC-61375standard. The analysis results show that MTTF(mean time to failure) of the redundant configuration is 20,086 hours,which is a about 3 times longer than the linear configuration.
