摘　　要：我国地域广阔、地形复杂、气候多变,输电系统面临相当严重的覆冰灾害威胁。导线覆冰导致的电力系统事故,严重影响了正常的国民经济生活。为了保证电网系统安全可靠的运行,有必要对输电线路导线覆冰的预测模型进行深入研究。首先总结了电线覆冰的相关气象因素,然后列举了一些比较典型的经验和半经验模型,综合阐述了覆冰物理过程的流体力学和热力学理论,最后对国内的覆冰预测模型研究现状做了简要介绍。China’s various territories,complex terrain and changing climate,results in frequent power line icing disaster,which is a serious threat to the normal national economic life.It is necessary to conduct in-depth study of ice coating of transmission line wires to ensure the safe and reliable operation of the power grid system.This paper firstly summarizes the relevant meteorological factors that cause the powerline icing,then enumerates some typical examples of empirical and semiempirical models of ice coating.The hydrodynamics and thermodynamics of the icing process are also described.The advantages and disadvantages of each model are compared and analyzed,and some recently developed statistical forecasting methods are briefly introduced.Finally the research status of domestic powerline icing prediction model is briefly reviewed.
