With the rapid development of ubiquitous power internet of things, a large number of sensing and monitoring nodes are deployed across all aspects of the power system to enable real-time monitoring of power equipment operating status and surrounding environmental parameters. However, the traditional power supply mode has gradually failed to meet the power supply demand of the sensor nodes in the power system, especially for transmission systems in the complex outdoor environment. To address this, a self-powered multi-wind driven energy acquisition is proposed, based on the triboelectric nanogenerator (TENG) that combines a rotary TENG and a flapping TENG. The collector of two modules:wind energy acquisition module based on the combination of rotating TENG, and wind vector sensing module based on flapping TENG. Firstly, the output characteristics of the wind energy acquisition module are tested and analyzed, and the hybrid power supply strategy of the backup power supply is proposed to realize the efficient power supply of commercial temperature and humidity sensors under the multi-stage wind speed from low to high. Secondly, experiments demonstrate that the wind vector sensing module can respond sensitively to eight direction wind vectors in the range of 2.6~13.5 m/s. The logical relationship between wind vector and the aeolian vibration is established to evaluate abnormal wire vibration. Finally, on this basis, a self-driven sensing system consisting of an energy acquisition, an eight-channel signal acquisition circuit, and the ambient temperature, humidity and wind vector monitoring of the LabVIEW host computer is developed. The real-time monitoring of temperature, humidity, wind speed and wind direction is fully realized, and the aeolian vibration warning of the transmission line is realized through the multi-directional wind vector information in response to aeolian vibration.
