Abstract

Assessing the vibration signature produced by a rotating component of the wind turbine enables the identification of operational conditions and the detection of potential faults at an early stage. The main purpose is to enhance the sustainability of wind turbines while increasing the lifespan and uptime of their operational systems. This vibration analysis is based on the processing of the signal provided by sensors, which often incorporates piezoelectric transducers. This paper evaluates the consequences of employing piezoelectric sensors used for vibration measurement on electrical machines integrated into wind turbines by conducting a life cycle assessment (LCA). The widespread use of piezoelectric materials is due to their high sensitivity to vibrations, although their selection is also influenced by regulatory restrictions. This research focuses on the environmental impact of piezoelectric accelerometers used commonly in condition monitoring systems. The collected literature data on the manufacturing processes are inputted into the LCA model which is powered by the Ecoinvent 3 database. The impact assessment is carried out using the European ILCD 2011 Midpoint+ method by calculating the unique scores of the selected impact categories. The results are presented and discussed in terms of environmental indicators, as well as ecological recommendations on the design.

风力涡轮机状态监测系统中压电装置的生命周期评估

通过评估风力涡轮机旋转部件产生的振动信号，可以识别运行状况并及早发现潜在故障。其主要目的是提高风力涡轮机的可持续性，同时延长其运行系统的寿命和正常运行时间。这种振动分析以传感器提供的信号处理为基础，其中通常包括压电传感器。本文通过进行生命周期评估（LCA），评估了采用压电传感器对集成到风力涡轮机中的电机进行振动测量的后果。压电材料对振动的高灵敏度使其得到广泛应用，但其选择也受到法规限制的影响。本研究重点关注状态监测系统中常用的压电加速度计对环境的影响。收集到的有关制造过程的文献数据被输入到由 Ecoinvent 3 数据库支持的生命周期评估模型中。影响评估采用欧洲 ILCD 2011 Midpoint+ 方法，计算所选影响类别的唯一分数。评估结果将根据环境指标进行展示和讨论，并对设计提出生态建议。
