Conductor galloping may cause flashovers and even tower collapses. The available conductor galloping monitoring methods often employ acceleration sensors to measure the conductor translations without considering the conductor twist. In this paper, a new sensor for monitoring conductor galloping of transmission lines based on an inertial measurement unit and wireless communication is proposed. An inertial measurement unit is used for collecting the accelerations and angular rates of a conductor, which are further transformed into the corresponding geographic coordinate frame using a quaternion transformation to reconstruct the galloping of the conductor. Both the hardware design and the software design are described in details. The corresponding test platforms are established, and the experiments show the feasibility and accuracy of the proposed monitoring sensor. The field operation of the proposed sensor in a conductor spanning 734 m also shows its effectiveness.
导线舞动可能会导致闪络甚至杆塔倒塌。现有的导线舞动监测方法通常使用加速度传感器来测量导线的平移，而未考虑导线的扭转。本文提出了一种基于惯性测量单元和无线通信的新型输电线路导线舞动监测传感器。惯性测量单元用于采集导线的加速度和角速率，通过四元数变换将其进一步转换到相应的地理坐标系中，以重构导线的舞动。详细描述了硬件设计和软件设计。建立了相应的测试平台，实验表明了所提出监测传感器的可行性和准确性。所提出的传感器在一条跨度为734米的导线上的现场运行也证明了其有效性。
