Abstract

The icing on power transmission lines, as a major hazard affecting the safety of electricity usage in China during winter, poses a significant challenge in systematically evaluating the weather conditions and their distribution characteristics during the icing period. Understanding the interaction between the microterrain and micrometeorology and achieving a refined analysis of the physical mechanisms during the icing process remain difficult tasks in this field. These are crucial aspects for the development of more accurate icing prediction models across southern China. Therefore, this study provides a comprehensive review and summary of the current research state and progress in the study of power transmission line icing in southern China from three perspectives: (1) large-scale circulation characteristics; (2) microphysical process, terrain–atmosphere interaction, microtopography and local micrometeorological conditions for the occurrence of icing events; and (3) numerical icing event modeling and forecasting. This study also looks ahead to the scientific issues and technological bottlenecks that need to be overcome for the prediction of ice coating on power transmission lines in southern China. The goal is to provide guidance for the causal analysis and forecasting warnings of power transmission line icing in the complex microterrain of the southern region.

中国南方输电线路结冰事件的原因与预测：回顾与展望

输电线路结冰是影响我国冬季用电安全的重大隐患，如何系统地评估结冰期间的气象条件及其分布特征是一项重大挑战。理解微地形和微气象之间的相互作用，实现对结冰过程中物理机制的精细分析，仍然是该领域的艰巨任务。这些对于开发更精确的华南地区结冰预测模型至关重要。因此，本研究从三个方面全面回顾和总结了中国南方输电线路结冰的研究现状和进展：（1）大尺度环流特征；（2）结冰事件发生的微物理过程、地形-大气相互作用、微地形和局地微气象条件；（3）结冰事件数值模拟和预报。本研究还展望了中国南方输电线路覆冰预测需要克服的科学问题和技术瓶颈。目的是为南方地区复杂微地形下输电线路覆冰的成因分析和预报预警提供指导。
