Reliability Assessment for Wind Turbine Under Index Weight and Failure of Subsystem

EasyChair Preprint 15886

Abstract

Wind turbine is a multi-system highly integrated complex facilities, once a subsystem fails, the wind turbine will stop running, and the influence of evaluation index to reliability on each subsystem to wind turbine have large differences. It is an urgent problem that to analyze the reliability that subsystem impact on the wind turbine. Considering the weight and model to analyze evaluation index and failure on the influence of reliability. For obtaining the reliability index weight, using Analysis Hierarchical Process (AHP) to divide layers of the wind turbine, influencing factors and subsystems, and the three scales method indicates the degree of influence on the reliability evaluation index of each layer under AGREE method, the reliability weights of each subsystem to the wind turbine are acquired by calculating judgement matrix. Based on the failure data of subsystems, considering the probability that a non-halting failure becomes halting failure on the influence of reliability, and model on Weibull distribution is proposed. Finally, analyzing the influence of subsystems in series system on wind turbine, assessment is based on the reliability weights and model against the subsystems.

Keyphrases: Weibull distribution, allocation, reliability weight, subsystem, wind turbine
