摘要:

设计了一种面向直驱式风力发电机气隙检测用的光纤传感器系统。首先,基于直驱式风力发电机气隙检测的需要,采用多模光纤原理对光纤束传感器探头进行了结构设计;进而,对光纤束传感器探头中接收光纤圈数,以及影响传感器特性参数的光纤纤芯半径r和入射光纤的数值孔径NA分别进行了仿真分析;然后,为了充分发挥整个系统的最高采集信号,在光纤探头的尾端进行了分束处理设计;最后,在实验室搭建了所设计的光纤传感器系统,并对其进行了静态标定。结果表明,该系统的量程范围可达8 mm,满足直驱式风力发电机气隙检测的需要。

Abstract:
A fiber optical sensor system for air gap detection of direct-drive wind turbine was designed. First, based on the need of detection, the structure of fiber optical beam sensor probe was designed by using a multi-mode fiber optic principle.Then, the number of received fiber turns from the fiber beam sensor probe, the radius r of fiber core and the numerical aperture NA of the incident fiber affecting the characteristic parameters of sensor were simulated and analyzed respectively. And, in order to utilize the highest acquisition signal of the whole system fully, the beam splitting process was designed at the end of the optical fiber probe. Lastly, the designed fiber optical sensor system was carried out in the laboratory and its static calibration was set up. The results show that the measuring range of the system was up to 8mm, which could meet the need of air gap detection of direct-drive wind turbine.
