With the vigorous advancement of smart power grid, online monitoring is essential for a stable operation of overhead transmission lines. The energy supply that drives the monitoring system has become one of the bottlenecks restricting the development of distributed sensing systems. In view of the self-excited vibration with the characteristics of low-frequency and large-amplitude generated in the conductor galloping, a hybridized generator has been designed to be composed of an electromagnetic generator (EMG), a horizontal TENG (H-TENG), and a vertical TENG (V-TENG) to provide an alternative approach for capturing mechanical energy derived from conductor galloping. Based on triboelectric–electromagnetic working principal, a sophisticated-designed stator and rotor structure oriented to the application scenarios of transmission lines successfully achieved self-power through the designed EMG and galloping state sensing through the designed H-TENG and V-TENG, respectively. The output performance, feasibility and durability of the hybridized generator was well validated on the linear motor platform and the conductor galloping test platform, and the output current was used to realize the characterization of the conductor galloping amplitude and galloping trajectory. This work not only provides an effective and sustainable solution to the self-powered intelligent sensor nodes in the complex surroundings of power transmission system, but also reveals TENG promising potential on the sensing applications in low-power monitoring sensors for conductor galloping.

随着智能电网的蓬勃发展，在线监测对于架空输电线路的稳定运行至关重要。驱动监控系统的能源供应已经成为制约分布式传感系统发展的瓶颈之一。针对导体舞动时产生的具有低频大振幅的自激振动特性，设计了一种由电磁发生器（EMG）、水平TENG（H-TENG）组成的混合发生器。 ，以及垂直 TENG (V-TENG)，以提供一种替代方法来捕获来自导体舞动的机械能。基于摩擦电-电磁工作原理，面向输电线路应用场景的精密设计的定子和转子结构，分别通过设计的 EMG 和通过设计的 H-TENG 和 V-TENG 成功实现了自供电和奔腾状态传感。混合发电机的输出性能、可行性和耐用性在直线电机平台和导体舞动测试平台上得到了很好的验证，并利用输出电流实现了导体舞动幅度和舞动轨迹的表征。该工作不仅为复杂环境下的自供电智能传感器节点提供了一种有效且可持续的解决方案，同时也揭示了TENG在低功耗导体舞动监测传感器传感应用方面的巨大潜力。
