| Abstract: |
| In this paper, the combined k-out-of-n : G model and reliability block diagram model is used to analyze the reliability of a switched reluctance starter/generator system. First, the different operational modes of a switched reluctance motor starter/generator are analyzed, and the fault states of the system are briefly described. Then the fault criteria of the system in different operational states are put forward. Secondly, a reliability block diagram model is established to calculate the system-level reliability, and the k-out-of-n : G model is adopted to analyze the reliability of each part of the switched reluctance starter/generator system. To verify effectiveness, the first-order Markov model is also used to analyze the reliability of each part of the switched reluctance starter/generator system. Considering the computational complexity and accuracy of the system, the k-out-of-n : G model is more suitable for system component level reliability analysis. Finally, a 6/4 switched reluctance motor is used as the simulated and experimental platform motor. The final results verify the effectiveness of the reliability analysis model. |
