摘要:Aiming at the problem of off-line deicing in overhead transmission lines, such as poor continuity of power supply and possible damage of lines caused by over-thick deicing, a new online anti-icing and deicing method based on external excitation resonance is proposed. The theoretical basis of the external excitation resonance to anti-icing and deicing is established. Then the modal characteristics of the external excitation resonance are determined through the modal analysis of the ice-coated transmission lines, and the reasonable frequency range of the external excitation resonance is obtained. According to the theoretical analysis and calculation results, the anti-icing and deicing robot system is designed by the external excitation resonance. Intelligent video technology is used to detect the icing condition of transmission lines in real time, and the vibration frequency range of transmission lines is analyzed and calculated. The vibration frequency is adjusted through the real-time tracking of the resonance feedback mechanism to ensure the continuity of the resonance working state, so as to effectively realize the efficient anti-icing and deicing of the transmission lines with the thickness of 1-3 mm at the initial icing stage. Finally, the parameters of the key components of the system are calculated and determined, and the related influencing factors are analyzed. A new deicing theory based on anti-icing theory is proposed, and specific engineering measures are given. (c) 2020 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
