摘　　要：结合风电机组自身系统状态特点,在可拓物元理论的基础上,建立了风电机组关键部件的多源物元描述模型.通过关联函数的引入,对国内某风电场主轴承采取润滑脂分析技术,建立多维定量化描述模型,并对其所处系统状态进行了可拓综合评价.Combining the characteristics of wind turbine system state itself, based on the extension matter ele- ment theory, this paper establishs a wind turbine key components multisource matter element model. Through the introduction of the correlation functions, the grease analysis technology is adopted in the main bearing of a wind farm in China, a multidimensional quantitative description model is set up; and then exten- sion comprehensive evaluation has been carried out. The results show that this method is good for wind tur- bine system status evaluation.
