摘　　要：分析了海上风电机组三种维修方案的优缺点,表明采用在线检测更加经济。对风机叶片发生故障机理进行了分析,并建立数学模型。分析了齿轮箱、发电机及液压系统机械故障机理,为在线检测提供理论参考。Both the merits and demerits of three maintenance schemes for offshore wind turbine are analyzed herein, and the con- clusion shows that the on-line fault detection and diagnosis is more economical. Furthermore, the fault mechanism of the blade of the wind turbine is analyzed, and then a relevant mathematical model is established as well. At last, the mechanisms of the mechanical faults from gear box, generator and hydraulic system are analyzed, so as to provide some theoretical references for the on-line diagnosis on wind turbine.
