Identification and detection technology of icing on high-voltage transmission lines under extreme conditions

Abstract： At the moment, an increasing number of high-voltage transmission lines must pass through substantially ice-covered locations, and transmission line breakdowns caused by snow and ice disasters occur on a regular basis, resulting in economic losses. As a result, it is required to investigate an effective detection technique for determining the state of ice-covered transmission lines in harsh conditions. This work presents and examines a weighted fusion approach for wavelet transform mode maximum and multi-scale and multi-structure morphology. Image preprocessing is performed on the acquired images using methods such as de-fogging, filtering, and gray augmentation, and the edge detection algorithm is achieved. By comparing the classical and commonly used edge detection operators, it is discovered that the error of this method is only 0.661 7% for the edge profile detection of ice-covered transmission lines under extreme conditions, which meets the requirements for the identification and detection of ice-covered transmission lines under extreme conditions. It provides technical assistance for calculating ice thickness and diagnosing transmission line faults.
