Abstract

This study investigates the use of POF (Plastic Optical Fibers) for mooring lines monitoring in floating wind turbines. Focusing on their mechanical adaptability and optical performance in marine environments. Optical attenuation measurement are employed to determine integrity of POFs under mechanical stresses such as tension and torsion, as well as during prolonged water immersion at ambient temperature. Key findings demonstrate a high deformation capacity of POFs (up to 70 % strain), with negligible loss in light transmission under mechanical stresses in tension and torsion. Additionally, water absorption was found to have a limited impact on optical attenuation, even after extended immersion. These results confirm the suitability in POFs for mooring lines monitoring in floating wind turbines. Furthermore, elongation measurements performed on POFs of up to 100 meters in length validated the feasibility of monitoring strain using both transmission and reflection OTDR (Optical Time Domain Reflectometer) measurement. The results highlight POFs as cost-effective, durable sensors capable of addressing the high-strain demands of mooring line applications.

用于浮式风力发电机系泊线监测的塑料光纤传感器：OTDR测量的可靠性研究

本研究探讨了POF（塑料光纤）在浮式风力涡轮机系泊线监测中的应用。重点研究了它们在海洋环境中的机械适应性和光学性能。采用光学衰减测量来确定POFs在机械应力（如拉力和扭转）以及在环境温度下长时间浸水时的完整性。主要研究结果表明，POFs具有很高的变形能力（高达70%的应变），在拉伸和扭转的机械应力下，光传输损失可以忽略不计。此外，研究发现，即使在长时间浸泡后，吸水对光学衰减的影响也有限。这些结果证实了POFs用于浮式风力发电机组系泊线监测的适用性。此外，在长达100米的pof上进行的伸长率测量验证了使用透射和反射OTDR（光时域反射计）测量来监测应变的可行性。结果表明，pof是一种具有成本效益、耐用的传感器，能够满足系泊线应用的高应变要求。
