Abstract:Ice accumulation on transmission lines poses severe hazards to the power grid system. Therefore, the accuracy of ice accretion prediction is crucial for the safe and stable operation of the power system. Based on a summary of previous mainstream ice accretion models, this paper conducts a comparative analysis of modeling factors. With quantifiability, ease of extraction, and significant impact on the regularity of ice accretion as selection principles, the paper employs SPSS software to establish models using multiple growth function relationships. Ultimately, the one with the best fitting effect is selected as the modeling result for the corrected ice accretion model. Verified by field-measured data, the corrected model demonstrates high practicality overall, with accurate ice accretion predictions and ice zone classifications, providing guidance for transmission line design.
