ABSTRACT: Reliability evaluation is important in high speed
railway external power supply design, based on probability reasoning bayesian
network applied in high-speed railway external power supply reliability
evaluation, establish the minimum cut and the minimum path of bayesian network
model, quantitative calculation external power supply system in each element
posterior probability, and the example analysis verified the feasibility and
correctness of the above method. Using bayesian network bidirection reasoning
technology, quantitative calculation the posterior probability of each element
in external power supply system, realized the identification of weak link in
external power supply. The research methods and the results of the study can be
used in the scheme optimization design of high speed railway external power
supply.
