Abstract

Transmission line icing in mountainous, high-latitude, and coastal regions poses serious threats to grid reliability by increasing conductor stress and causing tower failures or outages. Conventional monitoring approaches are limited by poor adaptability, low sensitivity, and reliance on external power sources. This study presents a self-powered ice weight monitoring method based on triboelectric nanogenerators (TENG) and micro thermoelectric generators (MTEG). A TENG-based ice weight sensing model and an MTEG thermal energy harvesting model are developed, and a prototype integrating MP-TENG, MTEG, signal processing, and energy management units is implemented. Experimental results demonstrate that MP-TENG accurately detects ice weight from 0 to 150 g with a maximum error of 1.26 % and measures growth rates of 0.01–0.8 mm/s with a maximum error of 2.34 %. Durability tests over 30,000 cycles show performance attenuation below 5 %. The MTEG achieves 1.2 V and 140 mA at 90 °C, providing 168 mW, sufficient to power the entire system for energy storage. The integrated system maintains a maximum error of 2.35 % across 50 repeated experiments, realizing continuous, high-precision, self-sustained ice weight monitoring. This work demonstrates a robust, fully autonomous sensing strategy for transmission line icing, combining high-accuracy measurement and sustainable energy harvesting, and provides a promising solution for smart grid applications in extreme environments.

基于摩擦纳米发电机和微热电发电机的输电线路自供电冰重监测

在山区、高纬度地区和沿海地区，输电线路结冰会增加导线应力，导致塔故障或停电，对电网可靠性构成严重威胁。传统的监测方法受到适应性差、灵敏度低和依赖外部电源的限制。提出了一种基于摩擦纳米发电机（TENG）和微热电发电机（MTEG）的自供电冰重监测方法。开发了基于teng的冰重传感模型和MTEG热能收集模型，并实现了集成MP-TENG、MTEG、信号处理和能量管理单元的原型机。实验结果表明，MP-TENG能准确检测0 ~ 150 g的冰重，最大误差为1.26 %；能测量0.01 ~ 0.8 mm/s的冰重，最大误差为2.34 %。超过30,000次循环的耐久性测试表明，性能衰减低于5 %。MTEG在90°C时达到1.2 V和140 mA，提供168 mW，足以为整个系统提供能量存储。集成系统在50次重复实验中最大误差保持在2.35 %，实现了连续、高精度、自持的冰重监测。这项工作展示了一种强大的、完全自主的输电线路结冰传感策略，结合了高精度测量和可持续能量收集，为极端环境下的智能电网应用提供了一种有前途的解决方案。
