摘　　要：随着风电装机容量的增加,风电机组需要更智能、更可靠的控制,这对变桨系统提出了新的要求。本文提出一种测量桨叶方位角和主轴转速的新方法,通过内置于变桨变频器的加速度传感器获取3个变频器的三向加速度分量,基于加速度分量可确定机组桨叶的方位角;另外,基于桨叶方位角的时间序列,可以计算得到机组主轴的转速。With the increase in wind power capacity,wind turbines require more intelligent and reliable control,thus posing new demands on pitch control systems.In this article,a new method for measuring blade azimuth and spindle speed is proposed,which obtains the three-dimensional acceleration components of three variable frequency drives by obtaining acceleration sensors embedded in the variable pitch variable frequency drive.Based on the acceleration component,the azimuth angle of the unit blades can be determined.In addition,based on the time series of blade azimuth angle,the speed of the main shaft of the unit is calculated.
