基于故障模式后果分析与动态故障树的高速铁路牵引变电所可靠性分析
Reliability Analysis of High-speed Railway Traction Substation Based on Failure Mode and Effect Analysis and Dynamic Fault Tree Analysis
摘要
Abstract
To improve the reliability of traction substation, the reliability of the electric traction substation is analyzed in view of the devices in the high-speed railway traction substation based on failure mode and effect analysis (FMEA) and dynamic fault tree analysis (DFTA). First, the reason for the failure of traction substation is analyzed according to the results of FMEA to seek targeted preventive measures, and then DFTA is employed to establish the high-speed railway traction substation fault model for qualitative and quantitative analysis to find out the weakness of the traction substation. Finally, comparison with the traditional fault tree calculation is conducted. The results show that there is a big error in the traditional fault tree modeling, and the combination of the two methods is more practical in reliability analysis than only one method.关键词
