| Abstract: | Aiming at the reliability of wind power plant, a fuzzy Failure Modes, Effect and Criticality Analysis (FMECA) evaluation model for wind turbine is proposed. Based on the statistics of annual operating data of Gold Wind Factory, the fuzzy evaluation theory is introduced to improve the fault evaluation of wind turbine. Through the establishment of Failure Mode and Effect Analysis (FMEA) fault table, this paper draws the hazard matrix and establishes the factor set, evaluation set and weight set to carry out fuzzy evaluation analysis. According to the evaluation results, the damage degree of each fault is rearranged. This study means great significance to further improve the efficiency of wind farm operation and maintenance and reduce maintenance costs.
