基于分布式光纤声波传感的OPGW光缆覆冰监测数据

随着电力传输距离不断延长，架空输电线路作为电力长距离传输的核心设备，其运行状态直接关系到供电安全。然而，冰冻、风振等自然因素常使线路下垂、摇摆甚至结冰，给电网安全带来潜在隐患。 基于分布式光纤声波传感的OPGW光缆覆冰监测数据集可用于判断线路舞动模式（如垂直舞、水平舞）的关键参数，可辅助建立舞动预测模型；快速估算冰层厚度，助力及时采取除冰措施。进一步地，还能结合实时振动监测数据，提前发出舞动风险警报。 具体而言，该数据集提供了OPGW光缆在不同测试条件下（光纤总长度、杆间距离、实际测试点、距离、覆冰重量、晃动等）的固有频率。数据集是利用Φ-OTDR技术、由分布式光纤声波传感（Distributed Optical Fiber Audio Sensing, DAS）设备采集的原始信号经处理后得到。Φ-OTDR技术具备以下显著优势：1.高灵敏度：能够捕捉亚毫米级覆冰厚度变化；2.实时监测：秒级响应速度，精准跟踪线路动态；3.抗干扰能力强：光纤传感无需外部供电，能有效抵抗复杂电磁环境的干扰。

As power transmission distances continue to increase, overhead transmission lines, as the core equipment for long-distance power transmission, their operational conditions are directly linked to power supply security. However, natural factors such as icing and wind vibration often cause lines to sag, sway, or even ice over, posing potential hidden dangers to power grid security.

The OPGW optical cable icing monitoring dataset based on Distributed Optical Fiber Audio Sensing (DAS) can be used to obtain key parameters for judging line galloping modes (such as vertical galloping and horizontal galloping), assist in establishing galloping prediction models, quickly estimate ice thickness, and help take de-icing measures in a timely manner. Furthermore, it can also be combined with real-time vibration monitoring data to issue galloping risk alerts in advance.

Specifically, this dataset provides the natural frequencies of OPGW optical cables under various test conditions, including total fiber length, pole span, actual test points, distance, ice coating weight, swaying, and others. The dataset is generated by processing raw signals collected by Distributed Optical Fiber Audio Sensing (DAS) equipment using Φ-OTDR technology.

Φ-OTDR technology has the following notable advantages:
1. High sensitivity: capable of capturing sub-millimeter scale changes in ice thickness;
2. Real-time monitoring: with second-level response speed to accurately track line dynamics;
3. Strong anti-interference capability: optical fiber sensing requires no external power supply, effectively resisting interference from complex electromagnetic environments.
