Research on Reliability Allocation Method of a Wind Turbine Generator System Under Multiple Factors
Aiming at the problem that the results of reliability allocation are relatively subjective at present,a reliability allocation method based on improved fuzzy analytic hierarchy process is proposed on the basis of the reliability allocation method of series sys-tems.The three-scale method is adopted for multiple factors affecting system reliability of the experts'judgments,the reliability al-location weight is initially determined by fuzzy analytic hierarchy process,and then the initial value of the allocation weight is pro-cessed by the entropy method,and the comprehensive allocation weight calculation model is established,eventually determine the reliability allocation weights of the components are determined,and the reliability allocation model of the mechanical systems is established.Taking the wind turbine generator system as an example,this method is applied to the reliability allocation of wind turbine generator systems.Through the improved fuzzy analytic hierarchy process,the traditional fuzzy analytic hierarchy process and other methods,the reliability allocation results of the wind turbine generator system are compared and analyzed.The results show that the method is not only effective;it is also lower than the allocation results based on the methods in the literature,and is more in line with the actual operating conditions of the unit,which verifies the rationality of the method.
