Reliability Analysis of Gas Turbine Based on Analytic Hierarchy Process and FTA

摘要

Gas turbine generator sets have complex structures and poor operating conditions, which place high demands on the reliability of components. Aiming at the structural characteristics of gas turbine generator sets, combined with the latest theory of reliability analysis development, based on the characteristics of the hierarchical structure of fault tree model, the combination of hierarchical analysis method and fault tree model is proposed to analyze the reliability of complex mechanical systems. In this paper, combined with the gas turbine startup failure, this method is applied to the analysis of the fault. The results show that this method is feasible and effective.
