The advantages of the triboelectric nanogenerator (TENG) in environmental energy harvesting and utilization determine that they have great development potential in the digital application of power grids. This work focuses on the harvesting and utilization of vibration energy from transmission lines, specifically in the context of breeze vibrations and sub‐span oscillations. To this end, this work proposes a novel multi‐mode vibrational triboelectric nanogenerator (MV‐TENG) and three smart transmission line application strategies based on the MV‐TENG. The MV‐TENG design consists of an S‐beam to broaden the frequency response range by reducing high‐order modal frequencies, and a pair of allegro electrodes to efficiently harvest horizontal and vertical vibration energy. The MV‐TENG demonstrates the capability to harvest vibration energy within a range of 1–3.5 Hz horizontally and 4 Hz, 9–60 Hz vertically, covering the occurrence range of breeze vibrations and sub‐span oscillations of transmission line effectively. Three application strategies include self‐powered tower obstacle alerting, temperature and humidity online monitoring, and high‐temperature wireless warning of transmission lines based on MV‐TENG. In summary, this work presents a comprehensive implementation scheme for digitally integrating TENGs into smart transmission lines, thereby facilitating the engineering development of TENG technology in grid systems.

“…In order to meet the long-term monitoring needs of transmission lines, the environmental energy harvesting technique is an alternative solution to provide sensors with powering and a promising pathway for the state-sensing field. Nowadays, extensive research focused on the piezoelectric generator (PEG), electromagnetic generator (EMG), and triboelectric nanogenerator (TENG) to capture micro-energy from the environment and convert it into electricity. − It is noteworthy that the vibration energy generated during the aeolian vibration of transmission lines provides feasibility for the application of self-powered systems and an effective solution for online monitoring of the vibration state of aeolian vibration in view of its vertical vibrational form. At present, several harvester prototypes of TENG, EMG, and PEG have been developed to collect the vibration energy of transmission lines. − Our research group demonstrated a triboelectric-electromagnetic hybridized harvester based on a sophisticated-designed stator and rotor structure and a swinging piezoelectric energy harvester based on frequency boost conversion; , both of them were used for conductor galloping energy harvesting and vibration state sensing.…”

In this work, based on the triboelectric-electromagnetic working principle, a comprehensive strategy appropriately hybridizes a multilayered elastic structure TENG (ME-TENG) and a doubleelectromagnetic generator (EMG) for efficient aeolian vibration energy harvesting and vibration state monitoring. The ME-TENG with the feature of elasticity is integrated with a movable plate embedded with a magnet as the counterweight, which acts as a spring-like mass system in response to external vibration excitation, making the inseparable integrity of the TENG and EMG. The basic hybridized triboelectric-electromagnetic aeolian vibration generator (HAVG) consisting of ME-TENG and double-EMGs in terms of structural parameters and response characteristics is first optimized and discussed, thereby the efficient vibration energy harvesting and effective vibration state response can be further improved through the mutual complementarity of TENG and EMG. Furthermore, the self-powered capacity of the HAVG in terms of LED arrays and a wireless ambient temperature and humidity monitoring system is verified through the hybrid charging strategy of TENG and EMG modules and the combination of HVAG and energy management circuits, benefiting from the sophisticated-designed structure and excellent output performance of the HAVG. Importantly, a self-powered aeolian vibration monitoring system is established and demonstrated for vibration-state sensing and abnormal vibration alarm. This work demonstrates a novel strategy for energy harvesting and state sensing of overhead transmission line aeolian vibration, which not only reveals TENG-EMG promising potential for energy harvesting for aeolian vibration, but also provides valuable guidance for the construction of a self-powered online-monitoring system for transmission lines.

To ensure the reliability and stability of long‐distance power transmission, it is necessary to monitor the health status of power transmission lines and the power grid environment. However, the utility of overmuch sensors could lead to adverse issues such as short battery life and susceptibility to environmental factors. To address this, an anti‐self‐excited oscillation triboelectric nanogenerator was proposed in this study, In the AO‐TENG structure, the original spacing rods of the power transmission line are modified. In the event of aeolian vibration in the power transmission line, the AO‐TENG generates electricity via cohesive work between the spring and the additional weight block, driving the TENG. Under specific conditions (300 g additional weight, 2.0 Hz vibration frequency, and 80 mm amplitude), the TENG can produce 125 μW of power. Additionally, an anti‐self‐limited power management circuit is used to process AO‐TENG power generation by utilizing the anti‐self‐excited characteristics of the capacitor. This prevents excessive impact voltage from damaging the back‐end circuit, and the capacitor plays an important role in voltage drop. Solve the problem that the high output voltage of the triboelectric nanogenerator is difficult to supply power to commercial sensors. Due to the integration of IoT, big data, information technology, sensor technology, and clean energy technology, the main difference between a smart grid and a conventional power grid is that a stable power supply method for distributed sensors in the power grid is required to transmit the monitored information to the terminal. This study introduces a new design solution to promote smart grids, which guarantees stable operation of distributed sensor nodes on such grids. The combination of TENG and smart grid also paves the way for clean, environmentally‐friendly, and low‐carbon goals, offering a reliable basis for smart grid operations.This article is protected by copyright.
