Abstract

The invention discloses a wind turbine generator reliability evaluation method and system considering manufacturing processes, and the method comprises the steps: calculating the weight of each manufacturing process through analyzing the manufacturing process parameters and witness modes of each part of a wind turbine generator; based on a fuzzy grey clustering method, defining a threshold range and a whitening weight function of each manufacturing process under each quality grade, calculating a grey clustering coefficient of each part under each quality grade and a weight of each part according to a score value and a weight of each manufacturing process, and on this basis, calculating a grey clustering coefficient of each part under each quality grade and a weight of each part; and a fuzzy evaluation operator is adopted to calculate a gray clustering coefficient of the whole wind turbine generator under each quality grade, the manufacturing process quality grade of the whole wind turbine generator is determined according to a gray clustering result, and evaluation of the inherent reliability of the whole wind turbine generator is realized. The influence of the manufacturing process on the inherent reliability of the wind turbine generator is fully considered, the reliability state of the wind turbine generator during delivery can be evaluated, and a reference basis is provided for model selection of the wind turbine generator.

Description

technical field [0001] The invention belongs to the technical field of reliability wind turbines, and in particular relates to a reliability evaluation method and system for a wind turbine considering a manufacturing process. Background technique [0002] The reliability evaluation of wind turbines can be divided into reliability evaluation for the design and manufacturing stage and reliability evaluation for the operation stage. The reliability evaluation for the design stage mainly includes FMEA, reliability allocation and reliability prediction, and the reliability evaluation for the operation stage The performance evaluation mainly includes failure statistical analysis and operational reliability analysis. [0003] Design-oriented reliability evaluation is an effective method to evaluate the future reliability status of products. The commonly used analysis methods can be summarized into three categories: similarity analysis method, statistical analysis method and failure...
