Abstract

Among all renewable energy sources, wind energy is a cost-effective alternative energy source. The majority of wind turbines are built in harsh environments due to their power generation characteristics, which is one of the prime reasons resulting in frequent failures of wind turbine. Among various failures, the vibration of wind turbine tower cannot be ignored because it is a precursor of the failure of the wind turbine. The electrical vibration sensors have the problems of power supply and electromagnetic interference for the condition assessment of wind turbine tower. A vibration sensor based on optical Fabry-Perot (F-P) interference principle with high sensitivity is designed, fabricated and characterized to further meet the requirements of vibration detection of wind turbine tower. The mechanical simulation model of the diaphragm and optical vibration platform is constructed to verify the sensing characteristic of the F-P optical fiber vibration sensor (OFVS). The experiment results indicate a resonant frequency of the F-P OFVS of 223 Hz, an output sensitivity of 122.22 mV/m·s⁻² at 10 Hz, and a horizontal output of less than 6 %. In addition, the designed F-P OFVS possesses the superiorities of compact structure, passive and excellent anti-electromagnetic interference, and has a wide application prospect in the vibration detection of the wind turbine tower.

基于光纤传感器的风力涡轮机塔架低频振动监测及其在物联网中的应用潜力

在所有可再生能源中，风能是一种具有成本效益的替代能源。由于其发电特性，大多数风力涡轮机都建在恶劣的环境中，这也是导致风力涡轮机故障频发的主要原因之一。在各种故障中，风力涡轮机塔架的振动不容忽视，因为它是风力涡轮机故障的前兆。电气振动传感器在对风力涡轮机塔架进行状态评估时存在供电和电磁干扰问题。为了进一步满足风力涡轮机塔架振动检测的要求，我们设计、制造并表征了一种基于光学法布里-珀罗（F-P）干涉原理的高灵敏度振动传感器。建立了膜片和光学振动平台的机械仿真模型，以验证 F-P 光纤振动传感器（OFVS）的传感特性。实验结果表明，F-P 光纤振动传感器的谐振频率为 223 Hz，10 Hz 时的输出灵敏度为 122.22 mV/m-s-2，水平输出小于 6%。此外，所设计的 F-P OFVS 还具有结构紧凑、无源、抗电磁干扰能力强等优点，在风力发电机塔架的振动检测方面具有广阔的应用前景。
