摘　　要：齿轮箱是风电机组传动系统的核心部分,一旦齿轮箱发生故障,不仅会产生高额的维修费用,还会造成较长时间的停电。因此,对风机齿轮箱进行实时状态监测与故障的识别、隔离具有重要的实际意义。而齿轮箱状态监测与故障识别、隔离的有效性依赖于齿轮箱中传感器所安装的位置和数量,因而有必要对齿轮箱传感器的配置进行研究。为了使安装的传感器不但可以准确反映齿轮箱的运行状态,还能对可能出现的故障实现识别与隔离,提出从风机齿轮箱的动力学模型出发,构建描述齿轮箱运行状态的动力学方程,将结构分析方法应用到齿轮箱传感器的优化配置中;实现传感器数量最少,识别、隔离可能出现的故障能力最大的配置目标。A gearbox is a premier part of the drive train in the wind turbine.Once the gearbox has fault,it will not only produce high maintenance cost but also result in longer power outages.Performing on-line condition monitoring and the early fault detection and isolability of the gearbox thus has important practical significance for the assessment of wind turbine health.However,the effectiveness of the on-line condition monitoring and the early fault warning mainly depends on the installation location and number of sensors in the gearbox.Therefore,it is necessary to study the sensor configure of the gearbox.To accurately reflect the operational status of the gearbox and detect and insulate the fault that may arise,a dynamic equation describing the gearbox behavior was built.The structural analysis method was applied to optimize the allocation of the gearbox sensor,achieve the optimization goals of maximum fault detection and isolation.
