Accurate ice thickness identification for transmission lines is crucial for resonant deicing. This study introduces a novel GMSA-Net model, achieving high accuracy in detecting ice thickness on power lines.
Area of Science:
- Electrical Engineering
- Computer Vision
- Materials Science
Background:
- Ice accumulation on transmission lines disrupts power system operations.
- Resonant deicing is an effective solution, but requires precise ice thickness data.
Purpose of the Study:
- To develop an accurate ice thickness recognition model for transmission lines.
- To enhance the efficiency and applicability of resonant deicing techniques.
Main Methods:
- Design of a Global Micro Strip Awareness Net (GMSA-Net) model.
- Introduction of Mixed Strip Convolution Module (MSCM) and global micro awareness module (GMAM) for feature extraction.
- Calculation of ice thickness via regional pixel statistics on segmented images.
Main Results:
- Achieved 96.4% mean Intersection over Union (mIoU) for image segmentation.
- Attained a balanced F-Score (F1-Score) of 98.1%.
- Ice thickness identification error was within 3.8%.
Conclusions:
- The GMSA-Net model accurately identifies transmission line ice thickness.
- The method provides a reliable basis for resonant deicing engineering applications.
